A.
Apnea
B.

D.
Hyperpnea
Show Answer
Correct Answer � C
Explanation
Ans. C. Cheyne-stokes breathing.
Cheyne-Stokes breathing is the most common type of periodic breathing.
The person breathes deeply for a short interval and then breathes slightly or not at all for an additional interval.
This pattern repeats itself about every minute.
Apnea is a transient cessation of respiration so it is true that Cheyne-Stokes breathing is associated with periods of apnea.
Biot breathing refers to sequences of uniformly deep gasps, apnea, and then deep gasps.
Hyperpnea means increased breathing, usually referring to increased tidal volume with or without increased frequency. Tachypnea means increased frequency of breathing.
