21
Q

Obstructive Disease is defined by

A

Expiration being Obstructed

22
Q

Restrictive Disease is defined by

A

Lung Inflation is being Restricted

23
Q

Compliance is defined as

A
  1. Ability to yield and stretch when under a force –“Distendable”
24
Q

Compliance =

A

The Change in Ventilation divided by the Change in Pressure

25
Q

What makes Surfactant in the Alveoli?

A

Type 2 Alveolar Cells

26
Q

Pressures will naturally flow from ______ alveoli into the _____ ones when a pressure gradient exists.

A

Small to Large

27
Q

Surfactant ‘detergent’ permits small alveoli patency and expansion even when connected to large alveoli.

A

KNOW THIS

28
Q

Surfactant modifies surface tension to ________.

A

Prevent collapse of small alveoli when connected to larger alveoli.

29
Q

How does surfactant increase compliance?

A

Decreasing Surface Tension

30
Q

Abnormally high compliance (Lung Volume is high and TPPG is lower)

A

Emphysema

31
Q

Abnormally low compliance (Lung Volume is low and TPPG is higher)

A

Pulmonary Fibrosis
