Medical Assistant Prep / Unit 4 MAS 083 short lesson, about 20 seconds
Breathing Rate and Lung Volumes
Captions available
The idea
At rest, an average adult takes roughly twelve to fifteen breaths a minute; one breath is one inhalation and one exhalation.
In practice
A spirometer measures how much air moves in and out of the lungs, and the test is called spirometry.
Where people slip
Lung capacity peaks in early adulthood and declines with age, so results are compared with expected values.
