40. •Tidal volume is a measure of the
amount of air a person inhales
during a normal breath. Traditional
preset tidal volumes higher than 10
ml/kg have been proved to be
associated with increased risk of
pulmonary barotrauma and should
be avoided. High tidal volumes also
decrease venous return and reduce
cardiac output.

41. •Residual volume is the only lung
volume that is not decreased
with respiratory muscle
weakness. Residual volume is the
amount of air left in the lungs at
the end ..

42. Roleof Hemoglobin
Hemoglobin is a heterotetrameric oxygen
transport protein found in red blood cells
(erythrocytes)
Roleof myoglobin
myoglobin is a monomeric protein found mainly in
muscle tissue where it serves as an intracellular
storage site for oxygen.
