Mechanics of Breathing
The ease in which lungs can be inflated. Decreases in the presence of scar tissue, congestion, and when there is a decrease in surfactant. Increases if elastic recoil is lost.
a. ) Respiratory pressures
b. ) Lung compliance
c. ) Airway resistance
b.) Lung compliance
The ease in which lungs can be inflated.
Compliance decreases in the presence of scar tissue, congestion, and when there is a decrease in surfactant.
Compliance increases if elastic recoil is lost.
Mechanics of Breathing
Air moves along pressure gradient created by changes in size of chest cavity during inspiration and expiration. Respiratory muscles work to increase dize during inspiration; expiration mostly related to elastic recoil of muscles and lung tissue.
