name 2 contraindications of PFTs
hemoptysis
MI
PE
acute chest/ abdominal pain
the primary problem in this type of disease is airway restriction
obstructive
the primary problem in this type of disease is reduced lung compliance
restrictive
is the relationship of resistance to flow rate direct or inverse
inverse
is the relationship of compliance to volume direct or inverse
direct
which gas can be used to identify the destruction of alveolar tissue or the loss of functioning alveolar surface area
carbon monoxide
for each measurement of pulmonary function there is a normal value and a ____ _____ ____. if the patients value fall below this value it indicated the presence of a pulmonary disorder
low limit of normal
