EMT Airway Exam|138 Questions withAnswers
Aerobic Metabolism - -Metabolism that can proceed only in the presence of
oxygen
- Agonal gasps - -Occasional, gasping breaths that occur agter the heart has
stopped
- Airway - -The upper airway tract or the passage above the larynx, which
include the nose, mouth and throat.
- Alveolar Minute Volume - -The volume of air moved through the lungs in 1
minute minus dead space; calculated by multiplying the tidal volume and
resp. rate
- Alveolar Ventilation - -Volume of air that reaches the alveoli. It is
determined by subtracting the amount of dead space air from the tidal
volume
- American Standard Safety System - -A safety system for large oxygen
cylinders, designed to prevent the accidental attachment of regulator to a
cylinder containing the wrong type of gas.
- Anaerobic Metabolism - -metabolism that takes place in the absence of
oxygen; principle by product is lactic acid.
- Apnea - -absence of spontaneous breathing
- Aspirations - -the introduction of vomitus or other foreign material into the
lungs
- Ataxic Respirations - -Irregular, ineffective respirations that may or may
not have an identifiable pattern
- Automatic Transport Ventilator (ATV) - -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) - -device with 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 - -a protective item such as a pocket mask with a valve,
that limits exposure to a patient's body fluids
- Bilateral - -A body part or condition that appears on both sides of the
midline
- Bronchioles - -Subdivision of the smaller bronchi in the lungs; made of
smooth muscle and dilate or constrict in response to various stimuli
- Copnography - -a noninvasive method to quickly and efficiently provide
information on a patient's ventilatory status, circulation and metabolism.
Effectively measures the concentration of CO2 in expired over time
- Capnometry - -A device that measures the amount of expired CO2,
capnometer
- Carina - -point at which the trachea bifurcates into the left and right
mainstem bronchi
- Chemoreceptors - -monitor the levels of O2, CO2, and the pH of the
cerbrospinal fluid and then provide feed back to the resp. centers to modify
the rate and depth of breathing based on the body's needs
- Compliance - -Ability of the alveoli to expand when air is drawn in during
inhalation
- Continous Positive airway pressure (CPAP) - -method of ventilation used
primarily in the treatment of critically ill patients with resp. distress; can
prevent the need for endotracheal intubation
- dead space - -portion of the tidal volume that does not reach the alveoli
and thus does not participate in gas exchange
- Diffusion - -process in which molecules move from an area of higher
concentration to an area of lower concentration
- dyspnea - -shortness of breath
- end-tidal - -the amount of CO2 present at the end of an exhaled breath
- external respiration - -the exchange of gases between the lungs and the
blood cells in the pulmonary capillaries; also called pulmonary respiration
- gag reflex - -a normal reflex mechanism that causes retching; activated by
touching the soft palate or the back of the throat.
