Body plethysmography
Mohammad solimny
Maher saied
Group 1862
Body plethysmography is a pulmonary (lung-related)
function test that determines how much air is in your
lungs after you take in a deep breath. It also
measures the amount of air left in your lungs after
you exhale as much as you can.
The principle of measurement of the commonly used
plethysmographs relies on detecting changes in box
pressure in combination with either changes of mouth
pressure or with
f
low rate under de
f
ined breathing
conditions. These signals are evaluated in order to
determine static lung volumes and air
f
low resistance.
