Respiratory Pathophysiology Flashcards
emphysema has two types
panacinar and centriobular
panacinar
-affects what structure
-which lobe
-cause
-big holes and empty spaces
-affects alveoli
-distributed t/o lungs
-loss of surface for air exchange
-lower lobes
-genetic
centriobulbar
-affects what structure
-which lobe
-cause
-upper lobes
-respiratory bronchioles;smaller airways affected
-smoking
-progression to chronic bronchitis
PaCO2 and PaO2 affects in emphysema
may be normal
-increased in hyperventilation
-slight decrease Q: muscle wasting, fatigue
