asthma

COPD

Question 13

of someones COPD is really bad what might kick in

Answer 13

hypoxic drive

Question 14

pulmonary fibrosis

thickened alveolar membrane

Question 15

restrictive lung disease findings

Answer 15

Reduced FEV1
Reduced FVC
They are reduced in proportion to each other

Question 16

hypoxia causes

Answer 16

impaired diffusion
hypoventilation
ventilation perfusion mismatch

Question 17

normal ventilation, low perfusion cause

Answer 17

PE

Question 18

normal perfusion, low ventilation cause

Answer 18

pneumonia

Question 19

how does perfusion change in pneumonia

Answer 19

increases due to vasodilation to bring more cells to the area
