Airway management Chpt. 9 Flashcards
Metabolism that can proceed only in the presence of oxygen.
Aerobic Metabolism
Occasional, gasping breaths that occur after the heart has stopped.
Agonal gasps.
The upper airway tract or the passage above the larynx, which includes the nose, mouth and throat.
Airway
The volume of air that reaches the alveoli. It is determined by subtracting the amount of “dead space” air from the “tidal volume”.
Alveolar ventilation
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.
Anaerobic metabloism
Absence of spontaneous breathing
Apnea
In context of airway, the introduction of vomitus or other foreign materiel into the lungs.
Aspiration
Irregular, ineffective respiration that mat or may not have an identifiable pattern.
Ataxic respirations
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.
Bag-mask device
A protective item, such as a pocket mask with a valve, that limits exposure to a patient’s body fluids.
Barrier device
A body part or a condition that appears on both sides of the midline.
Bilateral
Subdivision of the smaller bronchi in the lungs; made of smooth muscles and dilate or constrict in response to various stimuli
Bronchioles
Point at which the trachea bifurcates (divides) in to the left and right main stem bronchi (left and right lung)
Carina
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.
Chemoreceptors
The ability of the alveoli to expand when air is drawn in during inhalation.
Compliance
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.
Dead Space
A process in which molecules move from an area of higher concentration to an area of lower concentration.
Diffusion
Shortness of breath
Dyspnea
The passive part of the breathing process in which the diaphragm and the interconstal muscles relax, forcing air out of the lungs.
Exhalation
The exchange of gases between the lungs and the blood cells in the pulmonary capillaries; also called pulmonary respiration.
External Respiration
A normal reflex mechanism that causes retching; activated by touching the soft palate pr the back of the throat.
Gag Reflex
A condition in which air fills the stomach, often as a result of high volume and pressure during artificial ventilation.
Gastric Distention
The space in between the voal cords that is the narrowest portion of the adult’s airway; also called the glottic opening.
Glottis
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.
Hypercarbia
A dangerous condition in which the body tissues and cells do not have enough oxygen
Hypoxia
