EMT Fisdap Airway Exam Study Guide 2023 - 2024 (Verified)
1.Alveolar air volume: Amount of air that reaches alveoli for gas
exchange (approx. 350 ml. For adult male) Tidal volume minus dead space 2.Dead air space: Anatomically: structures that hold air, but can't participate in gas exchange.
Physiologically: alveoli or capillaries destroyed by disease
3.Expiratory reserve volume: Amount of gas that can be forcefully
expired at the end of a normal expiration
4.Inspiratory reserve volume: Amount of gas that can be forcefully
inspired in addition to a normal breaths tidal volume
5.Internal respiration: Exchange of gases between blood cells and tissues
6.Peak expiratory flow: The greatest rate of airflow during forced
expiration when lungs are fully inflated 7.Residual volume: After maximal forced exhalation, amount of air 1 / 2
- /
remaining not able to be expelled
8.Tidal volume: Amount of air in a respiratory cycle (500 ml, 5-7ml/kg)
9.Minute volume: Amount of gas moved in and out of respiratory tract
per minute
10.Air trapping: A respiratory pattern associated with an obstruction in
the pul- monary tree. Rate increases to overcome resistance
11.Angle of Louis: Angulation of the sternum that indicates the point
where the second rib joins the sternum. (manubriosternal junction)
12.Anoxia: total lack of oxygen available to the tissues
13.Apnea: Respiratory arrest
14.Atelectasis: Abnormal condition characterized by collapse of alveoli,
preventing exchange of co2 and o2 in a part of the lungs
15.Barrier device: Thin film of material placed on the patient's face used
to prevent direct contact with the patient's mouth during PPV
16.Carina: Where the trachea divides into right and left bronchi
17.Ronchi: Rattling or rumbling in the lungs. Inspiration and
expiration. Fluid in larger airways and may be cleared from a cough.
18.Stridor: Harsh, high-pitched inspiratory sound best heard over the
neck
