emt airway exam fisdap solved and
graded A+
aerobic metabolism - Answer Metabolism that can proceed only in the presence of
oxygen.
agonal gasps - Answer occasional, gasping breaths that occur after the heart has
stopped
alveolar minute volume - 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 - 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 - 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 - Answer The metabolism that takes place in the absence of
oxygen; the principle product is lactic acid.
apnea - Answer absence of spontaneous breathing
aspiration - Answer In the context of airway, the introduction of vomitus or other
foreign material into the lungs.
ataxic respirations - Answer Irregular, ineffective respirations that may or may not
have an identifiable pattern.
automatic transport ventilator (ATV) - 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) - 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 - Answer A protective item, such as a pocket mask with a valve, that
limits exposure to a patient's body fluids.
bilateral - Answer A body part or condition that appears on both sides of the midline.
Bronchioles - Answer Subdivision of the smaller bronchi in the lungs; made of
smooth muscle and dilate or constrict in response to various stimuli.
capnography - 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.
, emt airway exam fisdap solved and
graded A+
Capnometry - Answer A device that measures the amount of expired carbon dioxide.
carina - Answer Point at which the trachea bifurcates (divides) into the left and right
mainstem bronchi.
Chemoreceptors - 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 - Answer The ability of the alveoli to expand when air is drawn in during
inhalation.
continuous positive airway pressure (CPAP) - 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 - Answer The portion of the tidal volume that does not reach the alveoli
and thus does not participate in gas exchange.
Diffusion - Answer A process in which molecules move from an area of higher
concentration to an area of lower concentration.
Dyspnea - Answer shortness of breath
End Tital CO2 - Answer the amount of carbon dioxide present at the end of an
exhaled breath
Exhalation - 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 - Answer the exchange of gases between the lungs and the
blood cells in the pulmonary capillaries; also called pulmonary respiration
gag reflex - Answer A normal reflex mechanism that causes retching; activated by
touching the soft palate or the back of the throat.
gastric distention - Answer A condition in which air fills the stomach, often as a result
of high volume and pressure during artificial ventilation.
glottis - Answer The space in between the vocal cords that is the narrowest portion
of the adult's airway; also called the glottic opening.
good air exchange - Answer A term used to distinguish the degree of distress in a
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.
head tilt-chin lift maneuver - Answer A combination of two movements to open the
airway by tilting the forehead back and lifting the chin; not used for trauma patients.
