Which term denotes absence of breathing for more than 19 seconds?

Explanation:
Absence of breathing for a period is described as apnea. It means no air movement is occurring for long enough to be clinically meaningful, typically considered over about 10 seconds in adults and in some settings over 20 seconds. The other terms describe sounds or conditions while breathing continues: stridor is a high-pitched noise from an obstructed upper airway, crackles are crackling sounds from fluid in the lungs heard on auscultation, and wheezes are musical sounds from narrowed airways. So the term that denotes a true stop in breathing is apnea.
