the process by which molecules of gas move from an area
of higher concentration to an area of lower concentration
(alveolar and capillary). if ventilation & perfusion match you
get diffusion. If they don't match- VQ mismatch
Perfusion (Q)
Correct Answer
the process of transporting gases to the body (capillary)
via the circulatory system.
dead space ventilation
Correct Answer
alveoli receiving ventilation but not perfusion (pulmonary
emboli) ... aka air no blood
intrapulmonary shunting

2
Correct Answer
alveoli receiving perfusion but not ventilation (atelectasis,
pneumonia) ... aka blood no air
Cheyne-Stokes respiration
Correct Answer
pattern of breathing characterized by a gradual increase of
depth and sometimes rate to a maximum level, followed by
a decrease, resulting in apnea (cyclic crescendo)

Central neurogenic hyperventilation
Correct Answer
a pattern of rapid and deep breathing caused by injury to
the brain
apneustic breathing
Correct Answer
Abnormal respiration marked by prolonged inspiration;
accompanies damage to upper pons.

Correct Answer

3
Respirations that are regular but abnormally deep and
increased in rate, seen in metabolic acidosis (DKA), blowing
off excess co2
biots respirations
Correct Answer
irregular respirations of variable depth (usually shallow),
alternating with periods of apnea

Crackles:
Exampromax - Stuvia US
Correct Answer
A common, abnormal respiratory sound consisting of
discontinuous bubbling noises heard during inspiration.
Fine crackles have a popping sound produced by air
entering distal bronchioles or alveoli that contain serious
secretions, as in CHF, pneumonia, or early TB. Coarse
crackles may originate in the lg bronchi or trachea and have
a lower pitch. Crackles are not cleared by coughing.
Formerly called rales.
Rhonchi
Correct Answer
An abnormal sound heard on auscultation of an airway
obstructed by thick secretions, muscular spasm, neoplasm,
or external pressure. The continuous rumbling sound is
more pronounced during expiration and characteristically
clears on coughing.
