Flashcards in Airway management Chpt. 9 Deck (75)
Metabolism that can proceed only in the presence of oxygen.
Occasional, gasping breaths that occur after the heart has stopped.
The upper airway tract or the passage above the larynx, which includes the nose, mouth and throat.
The volume of air that reaches the alveoli. It is determined by subtracting the amount of "dead space" air from the "tidal volume".
A safety system for large oxygen cylinders, designed to prevent the accidental attachment of a regulator to a cylinder containing the wrong type of gas.
American Standard System
The metabolism that take place in the absence of oxygen; the principle product is lactic acid.
Absence of spontaneous breathing
In context of airway, the introduction of vomitus or other foreign materiel into the lungs.
Irregular, ineffective respiration that mat or may not have an identifiable pattern.
A ventilation device attached to a control box that allows the varibles of ventilation to be set. it frees the EMT to perform other tasks while the patient is be ventilated.
Automatic Transport Ventilator (ATV)
A device with a one-way valve and a face mask attached to a ventilation bag; when attached to a reservoir and connected to oxygen, delivers more than 90% supplemental oxygen.
A protective item, such as a pocket mask with a valve, that limits exposure to a patient's body fluids.
A body part or a condition that appears on both sides of the midline.
Subdivision of the smaller bronchi in the lungs; made of smooth muscles and dilate or constrict in response to various stimuli
Point at which the trachea bifurcates (divides) in to the left and right main stem bronchi (left and right lung)
Monitor the levels of O2, CO2, and the pH of the cerebrospinal fluid and then provide feedback to the respiratory centers to modify the rate and depth of breathing based on the body's needs at any given time.
The ability of the alveoli to expand when air is drawn in during inhalation.
A method of ventilation used primarily in the treatment of critically ill patients with respiratory distress; can prevent the need for endotracheal intubation.
Continuous Positive Airway Pressure (CPAP)
The portion of the tidal volume that does not reach the alveoli and thus does not participate in gas exchange.
A process in which molecules move from an area of higher concentration to an area of lower concentration.
Shortness of breath
The passive part of the breathing process in which the diaphragm and the interconstal muscles relax, forcing air out of the lungs.
The exchange of gases between the lungs and the blood cells in the pulmonary capillaries; also called pulmonary respiration.
A normal reflex mechanism that causes retching; activated by touching the soft palate pr the back of the throat.
A condition in which air fills the stomach, often as a result of high volume and pressure during artificial ventilation.
The space in between the voal cords that is the narrowest portion of the adult's airway; also called the glottic opening.
A term used to distinguish the degree of distress in patient with a mild airway obstruction. With good air exchange, the patient is still conscious and able to cough forcefully, although wheezing may be heard.
Good air exchange
A combination of two move-ments to open the airway by tilting the forhead back and lifting the chin; not used for trauma patients.
Head Tilt-chin life maneuver
Increased carbon dioxide level in the blood-stream.
