Improper airway management may directly threaten patients' lives due to respiratory failure. In many clinical settings, especially in emergency care, surgery, anesthesia, and intensive care units, nurses are responsible for managing patients' airways. Bever Medical will share complete information about airway management in nursing including types, nursing considerations, etc. It is very suitable for beginners to know and master the basics of airway management.   What is Airway Management? Airway management refers to the process of ensuring that a patient's airway remains clear and effectively supports their breathing. It is aimed at preventing airway obstruction, maintaining oxygen flow to the lungs, and preventing carbon dioxide buildup, thus ensuring normal physiological function.  Airway management is fundamental to emergency medicine and is indispensable in life-threatening situations, as improper methods can lead to hypoxia or even be life-threatening. Moreover, must prioritize patient safety and comfort and adjust patients' approach based on their needs. When Need Airway Management? If the patient has the following signs, it means take action on airway management: Mild airway obstruction: Such as choking (foreign object blocking the airway). Severe cases: Respiratory failure, loss of consciousness, airway injury, or airway inflammation. Emergencies: Such as complete airway blockage or trauma (e.g., penetrating injuries). The most common causes of airway obstruction are tongue collapse, foreign objects, or an excess of secretions (like mucus or saliva).  Types of Airway Management Oropharyngeal Airway (OPA) It is a curved plastic piece placed in the mouth to prevent the patient's tongue from sliding back into the throat and blocking the airway. Generally, it is used for Patients who are unconscious or semi-conscious, because awake patients may vomit or cough due to the irritation. Nasopharyngeal Airway (NPA) This is a soft tube inserted through the nose into the back of the throat, ensuring smooth airflow. Compared to OPA, NPA is less irritating to the patient. It is a better choice for patients whose mouth is tightly closed or when conscious but require breathing assistance.  Endotracheal Tube (ETA) This is a plastic tube inserted through the mouth into the trachea, directly connecting to a ventilator to assist with mechanical ventilation. It is mainly used for critically ill patients or those undergoing surgery to ensure sufficient oxygen delivery to the lungs. Tracheostomy Tracheostomy is a surgical procedure where a small hole is made in the trachea, and a tube is inserted. It is used for patients requiring long-term respiratory support, especially those needing prolonged mechanical ventilation. Compared to endotracheal intubation, tracheostomy is more suitable for long-term use and has a lower risk of discomfort and complications.  Steps in Airway Management The basic steps of airway management can be broken down into the following stages:  Assessing the Airway Initially assess the patient's breathing status to determine whether there is difficulty breathing, apnea, or airway obstruction. In intensive care settings, devices such as pulse oximeters and ventilators can be used to monitor oxygen levels and breathing.  Clearing the Airway Remove secretions, foreign objects, or blood clots from the mouth, throat, or airway to prevent obstruction. When the patient is unable to cough up secretions on their own, should use suction or suction catheters to clear the airway, especially Remove secretions, foreign objects, or blood clots from the mouth, throat, or airway to prevent obstruction. When the patient is unable to cough up secretions on their own, should use suction or suction catheters to clear the airway. Maintaining Airway Patency Based on the patient's condition, choose the appropriate airway management equipment, such as a nasopharyngeal tube, oropharyngeal airway, or endotracheal intubation, to ensure airway patency. For unconscious or semi-conscious patients, using airway management tools is necessary. When using intubation devices, ensure proper placement to prevent accidental displacement. Observation and Monitoring Airway management is an ongoing process, not a one-time procedure. Nurses need to regularly check the function of the equipment and monitor the patient’s oxygen saturation and breathing rate. In some cases, mechanical ventilation or oxygen devices may be required for further support.  Documentation and Communication During the nursing process, nurses must carefully document the airway management steps and the patient's responses. Regular communication with other medical team members is essential to ensure effective airway management.  PVC Nasopharyngeal Airway  Nursing Considerations in Airway Management Equipment Selection and Intubation Skills Nurses must choose the appropriate airway management equipment based on the patient's specific condition. Different devices have different indications and requirements, so nurses must be thoroughly familiar with these devices. Proper technique during intubation is crucial, and nurses must ensure correct placement to avoid errors such as misplacement or displacement. Avoiding Airway Injury Improper techniques may lead to airway injuries, such as trauma to the oropharyngeal region or tracheal damage during intubation. Careful and gentle handling of airway devices is necessary to avoid excessive force. Infection Prevention Maintaining device cleanliness and adhering to sterile techniques are critical to preventing infections. Long-term use of airway devices increases the risk of bacterial infections, so nurses should regularly clean equipment and monitor for signs of infection. They should also observe the patient's temperature, breathing, and secretions to identify any infection early. Psychological Care If patients need to use a ventilator or an endotracheal tube for the long term, they may feel discomfort, anxiety, or fear. Nurses should talk with patients to ease anxiety and provide emotional support.  Regular Monitoring and Assessment It is important to do ongoing monitoring and assessment. Regularly checking oxygen saturation, respiratory rate, and blood gas results can ensure the effectiveness of airway management. If oxygen saturation decreases or other bad signs appear, nurses should promptly take action. Takeaway Airway management is a crucial task in nursing, it can influence patient safety. Nurses should master airway management techniques and devices to ensure airway patency and maintain respiratory function.

Nasopharyngeal airways play a critical role in maintaining an open airway, helping patients clear mucus and relieving airway obstructions. Besides, it has a wide range of uses. You've come to the right place if you are a beginner learning related knowledge. Bever Medical will share complete information about nasopharyngeal airways here.   About Nasopharyngeal Airways A nasopharyngeal airway (NPA), commonly called an NPA, is a simple and convenient hollow tube with both ends open. Made from soft, smooth materials like PVC, it is a non-tracheal airway device placed outside the glottis. Its principle is to create a passageway in the nasopharynx, supporting collapsed soft tissues and repositioning the tongue forward. Such design plays a great role in relieving airway obstructions, suctioning mucus, and maintaining airway patency. Compared to oropharyngeal airways, PVC nasopharyngeal airways cause less irritation to the throat, and are an ideal choice for patient comfort and effective airway management.  Uses of Nasopharyngeal Airways 1. Maintaining Airway Patency One of the main uses of an NPA is to keep the airway open. When the tongue falls back (tongue obstruction) or soft tissue collapses, an NPA supports the airway, ensuring smooth airflow. This is essential for unconscious or comatose patients, as it prevents airway blockages.  2. Alternative for Patients Unable to Open Their Mouths When patients cannot open their mouths due to clenched teeth, facial injuries, or oral trauma, NPAs serve as an ideal alternative. They are especially useful for patients with oral swelling, trauma, or obstructions, effectively preventing breathing difficulties caused by an inability to insert an oral airway.  3. Emergency and Anesthesia Use In emergencies, such as during cardiopulmonary resuscitation (CPR), NPAs help maintain airway patency and ensure oxygen delivery to the lungs. In anesthesia, they prevent airway obstruction during surgery, ensuring a consistent oxygen supply throughout the procedure. 4. Suctioning and Secretion Clearance NPAs can guide suction catheters, assisting healthcare professionals in clearing mucus or foreign matter from the nasal and pharyngeal areas. This is crucial for maintaining airway patency, particularly when prompt airway clearance is needed to restore normal breathing.  5. For Emergency Cases and Special Populations Tongue obstruction often blocks the airway during seizures. An NPA can effectively maintain airway patency and support breathing. For trauma patients, especially those with head, facial, or neck injuries, NPAs provide a safer option, minimizing excessive airway irritation.  6. Suitable for Long-Term Use Generally, NPAs are made of soft medical-grade silicone or PVC, both of which can be left in place for extended periods without causing significant nasal irritation. This makes them particularly beneficial for long-term comatose patients or individuals needing prolonged use due to partial airway obstruction caused by tongue positioning. They are also used for oxygen delivery and suctioning.  Key Considerations for Use Proper Sizing After all, if it is too large or too small can reduce its effectiveness.  Lubrication Apply a suitable lubricant before insertion to minimize nasal mucosa damage. Contraindications NPAs are not recommended for patients with nasal bleeding, severe nasal injuries, or basal skull fractures, as they may cause further harm.  Potential Complications and Preventive Measures 1. Nasal Dryness and Minor Bleeding   Nasal dryness may happen to patients, because the tube needs to continuously support the airway, altering local airflow and leading to reduced moisture in the nasal mucosa. A dry nasal mucosa can weaken its barrier function, increasing the risk of cracks and minor bleeding. Patients are easily prone to nasal bleeding in dry climates or environments with low humidity.    Besides, the material of the nasopharyngeal airway can irritate the nasal mucosa upon contact. Improper lubrication or using a tube of the wrong size can further dry out or damage the nasal tissue, worsening bleeding symptoms. To minimize these risks, healthcare professionals should handle the tube carefully during insertion, avoid prolonged use, and regularly inspect the nasal cavity for signs of dryness or irritation.  2. Upper Respiratory Infections   Another common complication is an upper respiratory infection. Since NPA are placed in the nasopharyngeal region, they can become a potential breeding ground for bacteria, especially if the device is not kept clean or adequately disinfected. During use, the tube may accumulate secretions and bacteria, which can lead to local infections such as sinusitis or pharyngitis if not cleaned or replaced promptly.    To prevent infections, caregivers should ensure the tube is clean, replace it regularly, and monitor for symptoms such as fever, cough, or sore throat. Early recognition and treatment of infections are essential to prevent further complications. 3. Airway Injuries   Improper use of NPA may cause airway injuries, particularly if the tube is inserted with excessive force or placed incorrectly. This can result in minor trauma to the nasopharynx, nasal cavity, or other airway regions. Injuries are more likely in emergencies or with unconscious patients, as muscle relaxation and soft tissue collapse may increase the risk of friction or abrasion during insertion.    Symptoms of airway injury include pain, swelling, discomfort, and occasionally difficulty breathing or hoarseness. To avoid these issues, clinicians should select the appropriate NPA size, insert it gently, and ensure the correct insertion depth. Additionally, they should observe patient responses, and adjustments made if discomfort occurs.   4. Misplacement and Tube Obstruction   It is critical to maintain a clear airway to place NPA correctly. If it is improperly positioned or shifts due to changes in the patient’s posture, it may obstruct the airway and worsen breathing difficulties. Additionally, secretions or mucus may accumulate within the tube during prolonged use, leading to blockages and impairing airflow.    To prevent misplacement and obstruction, caregivers should regularly check the tube’s position and clear any secretions from the device. Moreover, proper patient positioning can reduce the risk of misplacement during insertion. Conclusion  NPA is highly effective in maintaining airway patency and have a wide range of uses. Though certain risks may happen when using a long time or wrong operation, these can be significantly minimized through appropriate equipment selection and proper operation.    Bever Medical provides customers with high-quality nasopharyngeal airway products, they are made from silicone and PVC materials, ensuring both comfort and safety during use.

Children's airways are narrower and more flexible compared to adults, so they are more susceptible to obstruction and respiratory issues. When such problems arise, pediatric airway management techniques can prevent sudden death. In most cases, medical staff can help maintain airway patency through routine methods like airway clearance and respiratory support. Therefore, it is important to select the right airway management ways. This article will introduce common airway management methods, let's have a look at the key features of pediatric respiratory function first. Key Physiological Features of Pediatric Respiratory Function Lung Capacity: Children have lower lung volumes compared to adults, which gradually increase with age. Tidal Volume: Younger children always have smaller tidal volumes. Airway Resistance: Children's airways have higher resistance, especially in cases of small airways, which makes airway obstruction more likely. Respiratory Reserve: Children have lower respiratory reserve and their breathing function is relatively fragile. Minute Ventilation: The minute ventilation (calculated by body surface area) is similar in adults but overall lower in children. Functional Residual Capacity: Children's lungs have less reserve capacity than adults. Gas Diffusion Capacity: The total surface area of capillaries in a child's lungs is smaller, which results in a lower gas diffusion capacity. Lung Elasticity: Children’s lungs have less elasticity, which limits their lung volume and recovery. Incomplete Alveolar Development: Newborns have only 8% of the alveoli found in adults, and their lungs are still developing, leading to less respiratory reserve. Anatomical and Physiological Features of Pediatric Airways Children's heads are disproportionately large, with shorter necks, larger tongues, and more prominent occiputs, which can cause airway constriction. Newborns and infants up to 5 months of age predominantly breathe through their noses, making nasal patency critical. Enlarged tonsils and adenoids in preschool children can cause upper airway narrowing. Generally, the epiglottis in children is epiglottis-shaped, which can affect intubation techniques. Newborns have limited alveolar numbers and less lung development, reducing their capacity for reserve breathing. Common Airway Management Methods 1. Face Mask  A face mask is the most basic method of ventilation and is widely used in pediatric anesthesia. However, in newborns and infants under 5 months, it can be challenging due to its potential to compress the nasal passages. Additionally, in preschool children with enlarged tonsils or adenoids, face mask ventilation may be more difficult. Prolonged mask use can also increase the risk of gastric insufflation and aspiration. 2. Oropharyngeal Airway  This airway is used to relieve upper airway obstruction due to an oversized tongue, particularly during anesthesia. It is crucial to select the correct size when using an oropharyngeal airway. By measuring the distance from the corner of the mouth to the angle of the jaw or earlobe, you can get the right size. Importantly, it must be placed at an appropriate depth to avoid obstructing the airway or pushing the epiglottis over the glottis, which could affect ventilation. It's also to be cautious as it can cause injury to the tongue or teeth, or slip out of position. 3. Nasopharyngeal Airway  NPA can relieve upper airway obstruction and maintain airway patency. However, this method can damage the mucosa in the nasal passages, especially in children with preexisting nasal ulcers or necrosis. The device may also accidentally slip into the esophagus, leading to inadequate ventilation and gastric insufflation. 4. Endotracheal Intubation   Endotracheal intubation is the standard for ensuring ventilation during general anesthesia. It provides an excellent oxygen supply during surgery and reduces the risk of aspiration. However, the anatomical features of children such as larger heads, shorter necks, and higher larynx position make intubation challenging. The procedure can cause trauma to the soft tissues of the larynx and lead to edema, resulting in respiratory distress. Moreover, intubation can have great effects on hemodynamics, causing increased blood pressure and heart rate, it may disrupt the normal course of surgery. 5. Laryngeal Mask Airway (LMA)   The LMA combines the advantages of both face masks and endotracheal tubes and is widely used in pediatric anesthesia. Compared to traditional intubation, LMA insertion is easier and doesn't require a laryngoscope. This method is also faster, and it creates a secure airway without causing trauma to the larynx and trachea. Studies show that LMA anesthesia is more effective in young children undergoing day surgery, as it better maintains hemodynamic stability and reduces the occurrence of respiratory complications and hypoxia. Conclusion The anatomical and physiological features of children's airways make airway management complex. Therefore, it is crucial to select the right method of airway management, helping quickly and effectively resolve airway issues and ensuring the child's respiratory safety.  When choosing an airway management product, it's recommended to use reliable and designed to suit the anatomical features of children. Bever Medical provides ideal airway management products to better accommodate children's anatomical structures, improving safety and ease of use. Any interests, welcome to contact us.

There are many materials for nasopharyngeal airways, PVC and silicone are two of the more common choices. Due to its unique performance characteristics, PVC nasopharyngeal airways have obvious advantages but also have disadvantages in patient use. Today, Bever Medical will share with you the benefits and limitations of PVC materials, as well as how to maintain them.  Nasopharyngeal Airway (NPA) A nasopharyngeal airway, also known as a nasopharyngeal tube, is a hollow, soft tube with a smooth interior, designed for simplicity and ease of use. A PVC nasopharyngeal airway refers to one made of polyvinyl chloride (PVC), categorized as a non-endotracheal airway device. Typically, it is placed outside the glottis, creating a passage in the nasopharynx. This tube helps support collapsed soft tissues, advances the tongue base forward to relieve airway obstruction, clear secretions, and maintain airway patency. Compared to oropharyngeal airways, nasopharyngeal tubes cause less irritation to the throat, offering greater comfort for patients during use.  Structure of the Nasopharyngeal Airway The nasopharyngeal airway consists of three main components:   Connector: Features a cavity running through its length, allowing for the insertion of a catheter to pass through the airway. The upper end has a conical interface to connect and secure oxygen supply tubing, while the lower end fits tightly with the sleeve.   Sleeve: A hollow tube that connects and fixes the tube and the connector, securing it to the tube’s opening.   Tube: One end of the tube is beveled for easier insertion, while the other end is fitted with a sleeve for stabilization.  Benefits of PVC Nasopharyngeal Airways 1. Good Biocompatibility and Durability  PVC's biocompatibility makes it suitable for short-term use, as it generally does not cause significant tissue damage. This quality contributes to its widespread application in medical devices. Its durability also makes it ideal for various environments, including emergency care and short-term medical interventions.

Airway management is a cornerstone of emergency medicine, anesthesia, and critical care. Nasopharyngeal airways (NPA) and oropharyngeal airways (OPA) are two common tools used to secure the airway, ensuring adequate ventilation and oxygenation. While both devices serve the primary purpose of maintaining a patent airway, they differ significantly in design, use cases, and clinical application. This document explores these differences in detail to help clinicians choose the most appropriate tool for a given situation. 1. What is an NPA? An NPA, or Nasopharyngeal Airway, is a flexible, tubular device inserted through the nostril into the nasopharynx to maintain airway patency. It is designed to bypass obstructions in the oropharynx and create a channel for airflow. Key Features of NPA: Material: Usually made of soft, pliable rubber or silicone to reduce trauma during insertion. Shape and Design: Cylindrical with a flared end to prevent complete insertion and a beveled tip for easier navigation through the nasal passages. Sizes: Available in various lengths and diameters to suit different patient anatomies, from pediatric to adult. Applications: Suitable for patients with an intact gag reflex or those who are semi-conscious. Commonly used in prehospital care, anesthesia, and intensive care units.

Crafted from medical-grade PVC material, this NPA is specifically engineered to meet the needs of emergency medical professionals, paramedics, and healthcare providers. Its thoughtful design, coupled with advanced materials, ensures both safety and comfort for patients in critical care situations. 2. What is an OPA? An OPA, or Oropharyngeal Airway, is a rigid device inserted through the mouth to prevent the tongue from obstructing the oropharynx. It is primarily used in unconscious patients who lack a gag reflex. Key Features of OPA: Material: Rigid plastic or rubber. Shape and Design: Curved to follow the anatomy of the palate and pharynx, with a flange to prevent over-insertion. Sizes: Available in various lengths to accommodate pediatric and adult patients. Applications: Commonly used in emergency settings, anesthesia, and airway management during cardiopulmonary resuscitation (CPR). Indicated for unconscious patients with no gag reflex to prevent airway obstruction caused by the tongue or soft tissues of the mouth. 3. Key Differences Between NPA and OPA 4. Advantages and Disadvantages NPA Advantages: Can be used in patients with intact gag reflex. Effective for conscious or semi-conscious individuals. Less risk of inducing vomiting or laryngospasm compared to an OPA. NPA Disadvantages: Risk of nasal trauma or bleeding during insertion. Contraindicated in basal skull fractures due to potential brain injury. May cause discomfort or irritation, especially in long-term use. OPA Advantages: Simple and quick to insert with minimal training. Highly effective in maintaining airway patency in unconscious patients. Prevents tongue-related airway obstruction during resuscitation or surgery. OPA Disadvantages: Cannot be used in conscious patients or those with an intact gag reflex. Risk of inducing vomiting or laryngospasm if used incorrectly. Not suitable for patients with oral trauma or jaw clenching. 5. Choosing Between NPA and OPA The choice between NPA and OPA depends on the patient's condition, level of consciousness, and the clinical scenario: Use NPA when: The patient is conscious or semi-conscious. There is a need to maintain airway patency in the presence of oral trauma or trismus (jaw clenching). The patient has a gag reflex that contraindicates OPA use. Use OPA when: The patient is unconscious and lacks a gag reflex. The primary cause of airway obstruction is the tongue or soft palate. A simple, quick solution is needed during resuscitation. 6. Conclusion NPA and OPA are both essential tools in airway management, each with specific indications and contraindications. Understanding their differences, appropriate use cases, and insertion techniques is crucial for effective airway management. Proper assessment of the patient's condition and anatomy will guide clinicians in selecting the most suitable device, ensuring optimal outcomes in emergencies and critical care scenarios.

In order to make safer and more effective decisions quickly in emergency situations, it is very necessary to know the applicability of the two airway tools. This is very helpful for first responders, medical staff or ordinary people who want first aid knowledge. As a supplier of airway management products, Bever Medical will share with you when to use NPA instead of OPA today. Differences Between NPA and OPA Functions   Nasal pharyngeal airways (NPA) and oropharyngeal airways (OPA) are commonly used airway management products in clinical practice to maintain airway patency. They share similar purpose, but they differ significantly in design, mechanism of action, and applicable scenarios:   1. NPA Functions  NPA (Nasal pharyngeal airways) is a soft, tubular device inserted through the nasal passage to extend into the nasopharynx, creating an artificial airway. It bypasses soft tissue obstructions in the upper airway, ensuring airflow in cases where the patient cannot open their mouth. Its flexible material and lubricated surface enhance patient comfort during insertion, making it particularly suitable for patients with intact gag reflexes.   2. OPA Functions  OPA (oropharyngeal airways), made of rigid, curved plastic, is inserted through the mouth and positioned along the tongue to reach the posterior pharyngeal wall. It prevents airway obstruction by displacing the tongue anteriorly, thus maintaining a clear passage. Due to its firm design and direct interaction with the tongue, OPA is most appropriate for unconscious patients without a gag reflex, as its use in conscious individuals may induce discomfort or vomiting.   Pre-Lubricated Nasal Airway Scenarios for Using NPA   1. Patients Unable to Open Their Mouths   NPA is ideal for patients with clenched jaws or oral injuries, such as those experiencing a seizure. It provides an alternative airway route through the nasal passage when the oral route is inaccessible.   2. Patients with an Intact Gag Reflex   For conscious or semi-conscious patients, OPA is often intolerable due to its rigid structure and potential to trigger the gag reflex. NPA, being softer and less invasive, is a more comfortable and viable option.   3. Presence of Facial or Oral Trauma   In cases of facial burns, maxillofacial fractures, or oral trauma where the use of OPA is contraindicated, NPA can bypass the affected area and provide effective airway support.   4. Temporary Airway Support   NPA is frequently used in emergency situations requiring short-term airway management, such as during CPR or at accident scenes, due to its quick insertion and ease of use.   Scenarios for Using OPA   1. Unconscious Patients   OPA is highly effective for unconscious patients, such as those under general anesthesia or in cardiac arrest, as it prevents the tongue from collapsing and obstructing the airway.   2. Patients Without a Gag Reflex   Since OPA contacts the posterior pharyngeal wall, it may provoke gagging or vomiting in patients with an intact reflex. Therefore, it is only suitable for unconscious individuals lacking this reflex.   3. Long-Term Airway Support   In scenarios requiring a stable airway for a prolonged period, such as intraoperative or postoperative care, OPA ensures a reliable airway while allowing easy access for healthcare monitoring.   4. Emergency Airway Management   In hospital or pre-hospital settings, OPA is often the first choice for managing airway obstruction in unconscious patients due to its rapid deployment and effectiveness.   Factors Influencing the Choice Between NPA and OPA   Selecting between NPA and OPA requires a comprehensive assessment of the patient's condition. Key factors include:   1. Patient’s Level of Consciousness   For conscious or semi-conscious patients, NPA is preferred as it avoids stimulation of the posterior pharyngeal wall, reducing discomfort. Conversely, OPA is better suited for unconscious patients requiring stable airway support.   2. Anatomical Considerations   Structural anomalies, such as nasal septal deviation, may hinder NPA insertion. Similarly, oral abnormalities, such as maxillofacial trauma or severe dental malocclusion, may limit OPA use.   3. Urgency of the Situation   In critical airway emergencies, such as cardiac arrest, OPA is often chosen for its rapid insertion and immediate resolution of obstructions. If the mouth cannot be accessed, NPA becomes the only viable option.   4. Patient History   Patients with a history of nasal bleeding or nasal surgery may not be suitable for NPA. Similarly, individuals allergic to latex should avoid using latex-based OPA devices.   Risks and Precautions for Using NPA and OPA   1. Risks Associated with NPA   Nasal Bleeding: Improper insertion or fragile nasal mucosa can cause bleeding. Adequate lubrication and avoiding forceful insertion minimize this risk.   Sinus Infection: Prolonged NPA use increases the risk of infection, necessitating regular replacement and sterile handling.   Misplacement: Incorrect placement may result in airway obstruction or even aspiration.  2. Risks Associated with OPA   Vomiting and Aspiration: OPA may induce gagging and vomiting in patients with a functional gag reflex, potentially leading to aspiration of gastric contents into the lungs.   Oral Trauma: Excessive force during insertion may damage teeth or oral tissues.   Worsened Obstruction: Incomplete insertion of OPA can push the tongue backward, exacerbating airway blockage.   3. Common Precautions   Both two airway management products must use appropriately sized devices to ensure effective and comfortable insertion.   Closely monitor the patient's breathing post-insertion to confirm airway patency.   Adhere to strict aseptic techniques to prevent infections.   Conclusion   Although this article provides the situation of choosing NPA instead of OPA, there are some situations that need to be combined with patient needs. Simply put, NPA is more suitable for patients with trismus, gag reflex, or facial trauma. Additionally, high-quality airway management products like those provided by Bever Medical are made of safe PVC and silicon medical materials. And OE services can meet the needs of patients and provide them with suitable materials and designs, providing safer and more comfortable solutions for airway management.
