Lecture 06 Pulmonary airway vs Alveolar dysfunction

______ dysfunction results in decreased oxygenation in blood, and _______ dysfunction results in normal oxygenation but reduced blood flow?

Both centrilobule and panlobule emphysema has loss of ______ and ______ destruction.

________ destruction is more often seen in centrilobule emphysema while loss of _______ is more often seen in panlobule emphysema.

T/F: patients with early emphysema may have near normal PaO2 and PaCO2.
