emt airway exam fisdap
aerobic metabolism - correct answer ==Metabolism that can proceed only in the presence of oxygen.
agonal gasps - correct
... [Show More] answer ==occasional, gasping breaths that occur after the heart has stopped
alveolar minute volume - correct answer ==The volume of air moved through the lungs in 1 minute minus the dead space; calculated by multiplying tidal volume (minus dead space) and respiratory rate.
alveolar ventilation - correct answer ==The volume of air that reaches the alveoli. It is determined by subtracting the amount of dead space air from the tidal volume.
American Standard System - correct answer ==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.
anaerobic metabolism - correct answer ==The metabolism that takes place in the absence of oxygen; the principle product is lactic acid.
apnea - correct answer ==absence of spontaneous breathing
aspiration - correct answer ==In the context of airway, the introduction of vomitus or other foreign material into the lungs.
ataxic respirations - correct answer ==Irregular, ineffective respirations that may or may not have an identifiable pattern.
automatic transport ventilator (ATV) - correct answer ==A ventilation device attached to a control box that allows the variables of ventilation to be set. It frees the EMT to perform other tasks while the patient is being ventilated.
bag-valve mask (BVM) - correct answer ==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, it delivers more than 90% supplemental oxygen.
barrier device - correct answer ==A protective item, such as a pocket mask with a valve, that limits exposure to a patient's body fluids.
bilateral - correct answer ==A body part or condition that appears on both sides of the midline.
Bronchioles - correct answer ==Subdivision of the smaller bronchi in the lungs; made of smooth muscle and dilate or constrict in response to various stimuli.
capnography - correct answer ==A noninvasive method to quickly and efficiently provide information on a patient's ventilatory status, circulation, and metabolism; effectively measures the concentration of carbon dioxide in expired air over time.
Capnometry - correct answer ==A device that measures the amount of expired carbon dioxide.
carina - correct answer ==Point at which the trachea bifurcates (divides) into the left and right mainstem bronchi.
Chemoreceptors - correct answer ==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.
compliance - correct answer ==The ability of the alveoli to expand when air is drawn in during inhalation.
continuous positive airway pressure (CPAP) - correct answer ==A method of ventilation used primarily in the treatment of critically ill patients with respiratory distress; can prevent the need for endotracheal intubation.
dead space - correct answer ==The portion of the tidal volume that does not reach the alveoli and thus does not participate in gas exchange.
Diffusion - correct answer ==A process in which molecules move from an area of higher concentration to an area of lower concentration.
Dyspnea - correct answer ==shortness of breath
End Tital CO2 - correct answer ==the amount of carbon dioxide present at the end of an exhaled breath
Exhalation - correct answer ==The passive part of the breathing process in which the diaphragm and the intercostal muscles relax, forcing air out of the lungs.
external respiration - correct answer ==the exchange of gases between the lungs and the blood cells in the pulmonary capillaries; also called pulmonary respiration
gag reflex - correct answer ==A normal reflex mechanism that causes retching; activated by touching the soft palate or the back of the throat. [Show Less]
