Clearing respiratory secretions is a way to relieve patients' breathing difficulties and help maintain clear airways. The flexible suction catheter is one of the most commonly used tools in secretions clearing. Importantly, it has wide use and is more comfortable. In this article, Bever Medical will share a complete overview of flexible suction catheters with you,  like their wide usage, and use tips, a guide on selection, etc.  What is a Flexible Suction Catheter? A flexible suction catheter is made from soft, smooth medical-grade materials with high flexibility to minimize airway irritation during suctioning. It is also named a soft suction catheter. For patients who find traditional rigid catheters uncomfortable, a flexible suction catheter is a more comfortable alternative when inserted into the airway. It is ideal for use in critical care, respiratory medicine, and geriatric departments, helping patients maintain clear airways, prevent infections, and improve comfort. Advantages Reduced Patient Discomfort Traditional catheters are often rigid and may cause patients, especially those with heightened sensitivity, to experience coughing or gagging. Soft suction catheters are softer and smoother, which reduces irritation. Enhanced Safety    These catheters have excellent kink resistance, which effectively prevents suction interruptions caused by twisting. Additionally, the soft material helps lower the risk of airway damage. Wide Use of Flexible Suction Catheters 1. Intensive Care Units (ICU)   ICU patients often require prolonged bed rest and continuous airway management. Nurses use suction catheters to quickly and safely clear the airway, reducing the risk of respiratory infections. And soft suction catheters reduce patient irritation and allow rapid airway clearance in emergencies. 2. Respiratory Medicine  For respiratory conditions such as chronic obstructive pulmonary disease (COPD) or asthma, flexible suction catheters efficiently clear airway secretions, helping patients breathe more easily and reducing the risk of complications during hospitalization. 3. Elder Care   Elderly patients often have delicate airways, making traditional rigid catheters uncomfortable or damaging. Flexible suction catheters offer a gentler suctioning method that improves their comfort and safety. Steps for Using a Flexible Suction Catheter 1. Ensure all equipment is clean and wear disposable gloves to maintain a sterile environment. 2. Open the catheter package and inspect it for any damage or defects. 3. Gently insert the catheter into the patient's airway with smooth and steady motions, avoiding forceful insertion. 4. Adjust the catheter position according to the patient's needs, clearing the airway secretions gently. 5. After completing suctioning, slowly remove the catheter from the patient's airway. Precautions Avoid inserting the catheter too deeply to prevent airway damage. Limit the suctioning time to avoid excessive oxygen depletion. If the patient experiences severe coughing, gagging, or discomfort, stop the procedure and monitor their condition. Clean the catheter after each use to ensure hygiene and safety for subsequent uses. How to Choose the Right Flexible Suction Catheter? 1. Medical-grade Material: High-quality flexible suction catheters are made from medical-grade materials. Bever Medical offers catheters made from safe materials, ensuring both effectiveness and patient safety. 2.

Suctioning helps patients clear airway secretions effectively and prevents them from breathing problems. And the correct suction catheter size is a key factor in effective suctioning. Because the wrong size can lead to tracheal damage, mucosal injury, or even blockage of the tracheal tube, deprivation. However, mastering the tips for choosing the right suction catheter can minimize risks and improve treatment outcomes. In this article, you can get the complete guide, let's get started. What is a Suction Catheter? The suction catheter is widely used in hospitals, clinics, and even home care settings. It consists of three parts, the catheter, suction control device, and connector. It aims to remove secretions, blood, or other fluids from a patient's airway or respiratory tract. The catheter connects to a suction source through its connector and is used to suction out mucus and secretions from the tracheal tube. It's a long, soft tube usually made of plastic or rubber. One end is connected to suction equipment like a vacuum pump, and the other end is inserted into the patient's mouth, nose, or tracheal tube to clear the airway. Important: Suction catheters are single-use, sterile products and should never be reused. Why is Proper Suction Catheter Important? Using the wrong size suction catheter can lead to several problems. For example, a small catheter may not remove airway secretions effectively. And may leave behind secretions, increasing the risk of airway blockage and infection, finally worsening the patient's breathing. On the other hand, a too one can take up too much airway space during suctioning, reducing airflow and causing oxygen deprivation. It may also cause more friction against the airway walls, increasing the risk of mucosal injury or bleeding. So, choosing the proper catheter ensures effective airway clearance while minimizing the risk of complications. How to Choose a Proper Suction Catheter for Patients? Calculating the catheter size is a crucial step in choosing the right suction catheter for the patient. It begins with knowing the tracheal tube size. Here are three common formulas to help you calculate the appropriate suction catheter size: Catheter Size Calculation Formula 1: Tracheal tube internal diameter (ID) × 3 ÷ 2, then select the next largest French size (Fr). Example: If the tracheal tube ID is 8 mm, the calculation is 8 × 3 ÷ 2 = 12. So, choose the next largest size, which is a 14Fr suction catheter. Formula 2: Tracheal tube internal diameter (ID) × 2, then select the next smaller French size (Fr). Example: If the tracheal tube ID is 8 mm, the calculation is 8 × 2 = 16. So, choose the next smaller size, which is a 14Fr suction catheter. Formula 3: Tracheal tube internal diameter (ID) × 2 - 2. Example: If the tracheal tube ID is 8 mm, the calculation is 8 × 2 - 2 = 14. So, use a 14Fr suction catheter. You can use any of these formulas to help determine the correct size for your patient’s tracheal tube. Material Some patients may have sensitivities or allergies to certain materials. The catheter should be made of a non-toxic, patient-friendly material. It should also be soft enough to reduce mucosal damage and allow for easy maneuvering. Catheters with Side Holes vs. Without Side Holes Suction catheters with side holes are generally more effective because they are less likely to get blocked by secretions. Larger side holes are typically more efficient. Patient Age and Gender Infants: Use a 5Fr - 8Fr Children: Use a 6Fr - 10Fr Adults: Use a 12Fr - 16Fr Catheter Length Suction catheters typically range from 30 to 50 cm in length. Must choose the right length according to the patient's airway size, it can ensure clear necessary area. Conclusion Selecting the right suction catheter ensures patient safety and effective airway clearance. Through proper size calculation formulas, considering the catheter material, and the patient's age and sex, your patients can get good care while reducing the risk of airway blockage, oxygen deprivation, or mucosal damage. Finally, remember to always prioritize the patient's comfort and safety, and make sure to use high-quality single-use catheters.

The reason why patients are in need of respiratory care is because they are not able to breathe properly and efficiently on their own, resulting in harmful conditions of inadequate oxygenation. People are interested in knowing about respiratory care, especially the fundamentals of respiratory care.  In this article, we discuss the aspects of respiratory care fundamentals such as anatomy of respiratory system, needs assessment, respiratory care provided, etc.    Anatomy and Physiology of Respiratory System In this part, we will understand the anatomy of respiratory system which includes the upper and lower respiratory tracts.  Upper respiratory tract The upper respiratory tract includes the nose, nasal cavity, mouth, pharynx, and larynx. They play an important role because these are the parts which filter, warm, and humidify the air we breathe. Lower respiratory tract The lower respiratory tract has such parts as the trachea, bronchi, bronchioles, and alveoli. The trachea divides into the right and left bronchi, which further branch into bronchioles and end in alveoli. The alveoli are the primary sites for gas exchange, where oxygen enters the blood, and carbon dioxide is expelled. Mechanics of breathing Breathing involves the coordinated action of the diaphragm and intercostal muscles. During inhalation, the diaphragm contracts and moves downward, creating negative pressure in the thoracic cavity, drawing air into the lungs. Exhalation is typically passive, with the diaphragm relaxing and air being pushed out of the lungs.  Anatomy of respiratory system Respiratory Assessment to Find out Causes To find out what is the reason behind your respiratory issues, the doctor has tools available such as asking you about your symptoms and occupational risks, performing medical examinations, and doing diagnostic tests.  Assessment questions After receiving patients with respiratory problems, the healthcare provider will try to find out the causes of the problem. Based on the causes they can provide effective care to improve patient health. They will ask you about respiratory symptoms, smoking history, occupational exposures, and past medical conditions in order to identify the causes.  Physical examination   The examination techniques used by the doctor are the following:  1) Observing the patient’s respiratory rate, effort, and symmetry 2) Palpation assesses for tenderness, masses, or subcutaneous emphysema 3) Percussion can determine lung density 4) Auscultation with a stethoscope detects abnormal breath sounds, such as wheezes or crackles. Diagnostic tests A. Pulmonary Function Tests (PFTs): These tests measure lung volumes, capacities, and flow rates, providing valuable information about the functional status of the lungs. B. Arterial Blood Gases (ABGs): ABGs assess oxygenation, ventilation, and acid-base balance by measuring the levels of oxygen, carbon dioxide, and bicarbonate in the blood. C. Imaging: Chest X-rays, CT scans, and MRI provide detailed images of the lung structures, helping to identify abnormalities such as tumors, infections, or fluid accumulation. Provision of Healthcare to Patients with Respiratory Issues To promote our understanding of the fundamentals of respiratory care, the following presents descriptions of healthcare interventions intended to improve patient respiratory health and well-being. Oxygen Therapy Oxygen therapy improves oxygenation in patients who has hypoxemia or experiences respiratory distress. In particular, oxygen therapy is provided by your healthcare provider in cases of chronic obstructive pulmonary disease (COPD), pneumonia and heart failure. During surgical procedures this therapy is also necessary.  The devices in this therapy are: A. Nasal Cannula delivers low to moderate concentrations of oxygen. B. Simple Mask provides higher concentrations of oxygen than a nasal cannula. C. Non-rebreather Mask delivers high concentrations of oxygen, typically used in severe hypoxemia. D. Venturi Mask allows precise control of oxygen concentrations, suitable for patients requiring specific oxygen levels. Oxygen saturation (SpO2) is monitored using pulse oximetry, a non-invasive method that provides continuous real-time data about the patient’s oxygenation status.  A patient being aided with oxygen therapy Mechanical ventilation In cases of severe respiratory failure, apnea, severe hypoxemia, and inadequate spontaneous ventilation, the healthcare provider will provide the patient with mechanical ventilation which supports patients with respiratory failure by ensuring adequate ventilation and oxygenation. Modes of ventilation A. Volume-Controlled Ventilation delivers a set volume of air with each breath. B. Pressure-Controlled Ventilation delivers air until a set pressure is reached. C. Assist-Control Ventilation provides full support with each breath, either initiated by the patient or the ventilator. D. Synchronized Intermittent Mandatory Ventilation (SIMV) allows patients to breathe spontaneously between mandatory breaths. Maintaining airway patency Maintaining airway patency is crucial for adequate ventilation and oxygenation. Here we would like to share with you the following things concerning maintaining airway patency: 1) Intubation is insertion of an endotracheal tube to maintain an open airway 2) Tracheostomy refers to surgical creation of an opening in the trachea to insert a tracheostomy tube, often used for long-term ventilation 3) Oropharyngeal Airway keeps the upper airway open in unconscious patients. 4) Nasopharyngeal Airway (NPA) is used in conscious or semi-conscious patients to maintain airway patency. NPAs help keep the airway open, especially in patients with partial obstructions due to conditions like sleep apnea, severe fatigue, or sedation. It is useful in preventing the collapse of soft tissues in the upper airway, which can obstruct airflow. By keeping the airway open, NPAs help ensure adequate ventilation and oxygenation, reducing the risk of hypoxia. The following is an image of a typical nasopharyngeal airway from a specialized and experienced manufacturer (you can refer to our website for more detailed descriptions: www.bevermedical.com)   Image of a typical nasopharyngeal airway Medicines used for respiratory care  1) Bronchodilators, such as albuterol and ipratropium, relax bronchial muscles, relieving bronchospasm and improving airflow. 2) Corticosteroids, like prednisone, reduce airway inflammation and are used in conditions such as asthma and COPD. 3) Mucolytics, such as acetylcysteine, thin mucus, making it easier to expectorate, thereby improving airway clearance. 4) Antibiotics are prescribed to treat bacterial respiratory infections, such as pneumonia and bronchitis. Respiratory diseases Various diseases affect your respiratory health, such as the following. Description of these diseases enriches our knowledge about respiratory care.  a. Chronic obstructive pulmonary disease (COPD), which includes chronic bronchitis and emphysema, is characterized by persistent respiratory symptoms and airflow limitation due to airway and/or alveolar abnormalities. b. Asthma is a chronic inflammatory disorder of the airways, resulting in reversible airway obstruction and bronchospasm. c. Pneumonia is an infection that inflames the alveoli, causing them to fill with fluid or pus, leading to cough, fever, and difficulty breathing. d. Pulmonary embolism is a blockage in one of the pulmonary arteries, usually due to blood clots that travel to the lungs from the legs or other parts of the body. e. Interstitial lung disease causes progressive scarring of lung tissue, leading to reduced oxygenation and respiratory function. Kindly Reminder Through the above descriptions we hope you know more about the fundamentals of respiratory care. If you or your loved ones experience respiratory discomfort it is important that you or they receive medical care that is available ASAP. 

If there are secretions, mucus, or other debris in their respiratory tracts, a suction catheter needs to be used to remove those matters in order to maintain airway patency and prevent respiratory infections. Therefor understanding suction catheters is helpful and important for patients and their concerned families and friends.   What Is a Suction Catheter?   A suction catheter is a thin, flexible tube designed to be inserted into the patient's respiratory tract, usually through the nose or mouth, to aspirate secretions and other fluids that may cause obstruction or infection. Made from materials such as plastic or silicone, suction catheters are sterile and disposable to ensure patient safety and prevent cross-contamination.   Construction of a Suction Catheter   Suction catheters, used for removing secretions, mucus, and other debris from a patient's respiratory tract, are carefully engineered in a way that ensures safety, effectiveness, and patient comfort.

For those who are acquainted with endotracheal tubes, there might be a desire to see some elaboration on cuffed and uncuffed endotracheal tubes. In this article we would like to share with you descriptions of these two types of endotracheal tubes.   As we know, an endotracheal tube is a flexible plastic tube that is inserted into the trachea (see definition below) through the mouth or nose. It can be used for maintaining airway patency, and is also useful to facilitate mechanical ventilation (see definition below).   Notes:   1) The trachea is the tube in humans extending from the larynx to the bronchi. It is the principal passage for conveying air to and from the lungs; it is also called the windpipe.   2) Mechanical ventilation: If the patient cannot breathe on their own, he/she will need to use a ventilator. The ventilator is a machine that moves breathable air in and out of the lungs.   The insertion of an endotracheal tube   Cuffed endotracheal tube   1) What is a cuffed endotracheal tube?   Cuffed endotracheal tube has an inflatable cuff near the end. The cuff is an inflatable balloon around the end of the tube. Made from silicone or rubber, the cuff, when inflated, presses tightly against the inner wall of the trachea, creating a seal that prevents leakage of air and other substances.   2) Applications where the cuffed endotracheal tube is used   A. During mechanical ventilation where the patient is ventilated with a high airway pressure, the cuffed endotracheal tube is the preferred type over the uncuffed type.   B. If the patient requires long period of ventilation, this is also the preferred type. The reason is that the cuff when inflated provides an effective seal and stability.   C. During laparoscopic surgery and cardiothoracic surgery, the seal between the trachea and tube is supposed to be high and effective, therefore cuffed endotracheal tube is preferred in both procedures. Besides, the use of cuffed endotracheal tube provides better benefits for monitoring respiratory mechanics (you can monitor it more accurately). Moreover, it reduces the loss of volatile drugs, thus helping to lower anesthetic costs.   3) Disadvantages of the Cuffed endotracheal tube   As you can see from section about the application of cuffed type of tube, this type’s advantages are apparent. So here we discuss its disadvantages.   A. Cuffed endotracheal tube has a relatively complicated structure. The insertion and removal of it take certain level of skill.   B. You need to be able to precisely control the extent to which the cuff is inflated otherwise over-inflation will cause damage to the tracheal wall.   C. If used in children under 8 there is a significant risk of damaging the laryngeal part or the tracheal mucosa.   Uncuffed endotracheal tube   1) What is an Uncuffed endotracheal tube?   An uncuffed endotracheal tube does not have a cuff. Its tube shape and diameter adapt to the trachea and is thus able to create a seal between the tube and the trachea. Due to its structural simplicity, the uncuffed endotracheal tube is easier to insert and remove.   2) Applications where uncuffed endotracheal tube is used   A. Infants and young children, especially those under the age of 8, traditionally have smaller and more delicate airways that can be easily damaged by a cuff. This is reason for use of this type of endotracheal tube. Besides, their cricoid cartilage often acts as a natural seal, making an artificial cuff unnecessary.   B. It is used in procedures or situations where intubation is expected to be brief. It is also used in situations where mechanical ventilation pressures are not high.   C. Uncuffed endotracheal tube is suitable for emergency tracheal intubation, for instance, we use an uncuffed endotracheal tube in emergency situations such as cardiopulmonary resuscitation because it is a convenient tool easier to insert and remove.   3) Disadvantages of uncuffed endotracheal tube   A. There may not be an effective seal between the tube and the trachea, resulting in leakage.   B. If the patient needs to undergo mechanical ventilation for a long period or if he/she needs to be ventilated with high airway pressure, the uncuffed endotracheal tube is not the suitable tube to be used.   To give you a vivid idea of these two different types of endotracheal tubes, please refer to the following image. If you are interested in specifications and other information about them, you can visit website: www.bevermedical.com   Cuffed and uncuffed endotracheal tubes from Bever Medical Devices   Recent trends   People are becoming more skillful in handling the cuff to avoid its negative effects. The cuff design is improving. The improved design of the cuffed tube minimizes pressure on the tracheal wall while providing an effective seal. So there is an increasing use of cuffed tubes in Pediatrics.   Important notes   As you can see from the above, cuffed and uncuffed endotracheal tubes have their respective advantages and disadvantages. They are selected to be used in situations where they are suitable, based on factors such as conditions of the patient, needs of surgery or treatment, experience and skills of the medical personnel. The applications of these two types of endotracheal tubes will be optimized and enhanced as medical technologies advance and research intensifies.
