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. Bever Medical provides high-quality airway management products, offering rich options for nurses during procedures.

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.
