Which of the following is a muscle that is used for expiration
sternocleidomastoid
external obliques
diaphragm
external intercostals
scalenus
, external obliques
What is the transpulmonary pressure if pleural pressure is -7 cm
H2O and alveolar pressure is -3 cm H2O?
alveolar pressure- pleural pressure= -3--7= +4
A lung compliance test indicates that a 3 cm H2O change is
transpulmonary pressure generates a .9 liter change in lung volume.
What is the patients lung compliance?
compliance= transpulmonary pressure/ change in lung volume= .3
liters of air/cm H2O
Airway resistance across a set of airways is lowest under which of
the following conditions?
(in regard to airway radius being large or small and length of the
tube being small or large)
airway radius is large and the length of the tube is small
As the lungs fill with air and we move from a low lung volume to a
higher lung volume, airway resistance will _____.
increase linearly
decrease exponentially
increase exponentially
decrease linearly
all of the above
decrease exponentially
With respect to the path of O2 diffusion, the proper order for the
movement of oxygen across the pulmonary capillary membrane
is___.
alveolar epithelium, interstitial space, capillary basement
membrane, blood
When a gas in the blood such as oxygen fails to reach diffusion
equilibrium with the alveolar air as it leaves the pulmonary capillary
bed it is said to be ...
perfusion limited
