Chapter 11 Airway Management Flashcards
Agonal gasps
Occasional gasps that are ineffective attempts at breathing, occurring after the heart has stopped.
Alveolar minute volume
The volume of air moved through the lungs in 1 minute minus the dead space; calculated by multiplying tidal volume and respiratory rate
Alveolar ventilation
The volume of air that reaches the alveoli. It is determined by subtracting the amount of deadspace air from the tidal volume.
American standard system
A safety system for oxygen cylinders larger than size e, designed to prevent the accidental attachment of a regulator to a cylinder containing the wrong type of gas.
Anoxia
Absence of oxygen
Apnea
Absence of breathing; periods of not breathing.
Apneic oxygenation
A technique in which oxygen is administered via a high-flow nasal cannula is left in place during an intubation attempt, allowing for continuous oxygen delivery into the airways during all phases of the procedure.
Aspiration
The introduction of vomit or other foreign material into the lungs
Ataxic respirations
Irregular, ineffective respirations that may or may not have an identifiable pattern.
Atelectasis
A condition of airless or collapsed alveoli that causes pulmonary shunting, ventilation-perfusion mismatch, and possibly hypoxemia.
Bilevel positive airway pressure (BPAP
A form of noninvasive positive pressure ventilation that delivers two pressures. (Higher on ispiratory and lower on expiratory)
Bordon-gauge flowmeter
An oxygen flowmeter that is commonly used because it is not affected by gravity and can be placed in any position.
Bronchioles
Find subdivisions of the bronchi
Capnographer
A device that attaches between the endotracheal tube and ventilation device; provides graphic information about the presence of exhaled carbon dioxied
Capnometer
A device that performs the same function and attaches in the same way as a capnographer but provides digital reading of the exhaled co2.
Carina
Point at which the trachea bifurcates into left and right main stem bronchi
Cobra perilaryngeal airway (cobraPLA)
Supraglottic device with a shapt that allows the device to slide easily along the hard palate and hold the soft tissue away from the laryngeal inlet.
Colorimetric carbon dioxide detector
A device that attaches between the endotracheal tube and ventilation device. Changes color in presence of co2
Combitube
A dual-lumen airway device that is inserted blindly; permits ventilation of the patient whether the tube is placed in the esophagus or trachea.
Continuous positive airway pressure (CPAP)
A method of ventilation used primarily to treat critically ill patients with respiratory distress; can prevent the need for endotracheal intubation.
Denitrogenation
The process of placing nitrogen in the lungs with oxygen to maintain a normal oxygen saturation level during advaced airway management.
Dorsal respiratory group
A portion of the medulla oblongata where the primary respiratory pacemaker is found
Dyspnea
Shortness of breath or difficulty breathing.
Endotracheal (ET) intubation
Insertion of an endotracheal tube directly through the larynx between the vocal cords and into the trachea to maintain and protect an airway.
end-tidal carbon dioxide (ETCO2) monitor
A detection device for monitoring the amount of carbon dioxide in exhaled air that can be used to adjust oxygen administration or ventilations.
Esophageal intubation
Improper placement of an advanced airway device into the esophagus.
Gum elastic bougie
Flexible device that is inserted between the glottis under direct laryngoscopy; the endotracheal tube is threaded over the device, facilitating its entry into the trachea.
