Insertion. The correct size airway is chosen by measuring the device on the patient: the device should reach from the patient's nostril to the earlobe or the angle of the jaw. The outside of the tube is lubricated with a water-based lubricant so that it enters the nose more easily.
A nasopharyngeal airway is a soft rubber or plastic tube that is passed through the nose and into the posterior pharynx. Nasopharyngeal airways are produced in various lengths and diameters to accommodate for gender and anatomical variations.
Nasopharyngeal airway in packaging Nasopharyngeal airways (NPA) are rubber tubes with a flange at one end. When properly used and with the correct size it allows for air to flow between the nose into the lungs. To use choose the appropriate size.
The Combitube—also known as the esophageal tracheal airway or esophageal tracheal double-lumen airway—is a blind insertion airway device (BIAD) used in the pre-hospital and emergency setting. It is designed to provide an airway to facilitate the mechanical ventilation of a patient in respiratory distress .
The correct size OPA is chosen by measuring from the first incisors to the angle of the jaw. The airway is then inserted into the person's mouth upside down. Once contact is made with the back of the throat, the airway is rotated 180 degrees, allowing for easy insertion, and assuring that the tongue is secured.
A nasopharyngeal airway (NPA) is a flexible tube that is passed through the nose into the back of the throat. They are the artificial airways of choice in patients who are conscious and have intact gag reflexes because they are less likely to stimulate the gag reflex than oropharyngeal airways (OPAs).
Examples of blind insertion airway devices are: Combitube [1] EasyTube [1] Laryngeal tube. Laryngeal mask airway (a supraglottic airway device) [1] Nasopharyngeal airway. Oropharyngeal airway.
Alternative techniques for airway management and delivery of oxygen, volatile anesthetics or other breathing gases include the laryngeal mask airway, i-gel, cuffed oropharyngeal airway, continuous positive airway pressure (CPAP mask), nasal BiPAP mask, simple face mask, and nasal cannula.
Laryngeal mask airways are designed to be an easy way to secure the airway and ventilate a patient – they are easier to place than tracheal intubation due to the lack of muscle relaxants and laryngoscopy. They are also less likely to damage teeth or the larynx itself. It may form an air-tight seal.
The jaw-thrust maneuver is a first aid and medical procedure used to prevent the tongue from obstructing the upper airways. This maneuver and the head-tilt/chin-lift maneuver are two of the main tools of basic airway management, and they are often used in conjunction with other basic airway techniques including bag-valve-mask ventilation.
