Questions with 100% Correct Answers
Alveolar air volume - ✔✔amount of air that reaches alveoli for gas
exchange (approx. 350 ml. For adult male) Tidal volume minus dead space
Dead air space - ✔✔anatomic dead space are structures that hold air but
but can't participate in gas exchange. Physiologic dead space are alveoli or
capillaries destroyed by disease
Expiratory reserve volume - ✔✔amount of gas that can be forcefully
expired at the end of a normal expiration
Inspiratory reserve volume - ✔✔amount of gas that can be forcefully
inspired in addition to a normal breaths tidal volume
Internal respiration - ✔✔exchange of gases between blood cells and
tissues
Peak expiratory flow - ✔✔the greatest rate of airflow during forced
expiration when lungs are fully inflated
Residual volume - ✔✔after maximal forced exhalation, amount of air
remaining not able to be expelled

,Tidal volume - ✔✔amount of air in a respiratory cycle (500 ml, 5-7ml/kg)
Minute volume - ✔✔amount of gas moved in and out of respiratory tract per
minute
Air trapping - ✔✔a respiratory pattern associated with an obstruction in the
pulmonary tree. Rate increases to overcome resistance.
Angle of Louis - ✔✔angulation of the sternum that indicates the point where
the second rib joins the sternum. (manubriosternal junction)
Anoxia - ✔✔total lack of oxygen available to the tissues
Apnea - ✔✔respiratory arrest
Atelectasis - ✔✔abnormal condition characterized by collapse of alveoli,
preventing exchange of CO2 and O2 in a part of the lungs
Barrier device - ✔✔thin film of material placed on the patient's face used to
prevent direct contact with the patient's mouth during PPV
Carina - ✔✔where the trachea divides into right and left bronchi
Ronchi - ✔✔rattling or rumbling in the lungs. Inspiration and expiration.

, Rattles (ronchi) - ✔✔inflammation and mucus or fluid in larger airways
heard on inspiration. Associated with bronchitis or pneumonia
Crackles (rales) - ✔✔wet lungs - sounds like hair rolled in finger tips. fluid in
smaller airways, crackling or popping sound on inspiration, sound that
indicates presence of fluid in smaller airways
Croup - ✔✔viral infection in upper airway that sounds like a seal bark
Wheeze - ✔✔whistling sound heard on inspiration or expiration in pharynx,
trachea, bronchi
Biot's respirations - ✔✔irregular respirations and rate with periods of apnea
from increased ICP, brain damage at medulla, DKA, and OD'ing
Agonal respirations - ✔✔slow, shallow, irregular from anoxic brain injury
Central neurogenic hyperventilation - ✔✔similar to kussmaul respirations,
deep and rapid breathing from increased ICP
Cheyne-Stokes respiration - ✔✔a pattern of gradually increasing rate and
depth of breathing that tapers to slower and shallower breathing with a
period of apnea before the cycle repeats.
Hering-Breuer reflex - ✔✔a reflex that limits inspiration and prevents over
inflation
Hiccup - ✔✔spasm of the diaphragm
