Please visit this link for the Questions
01.
a. T - This response is the definition of TIDAL Volume
b. F - Residual volume is the amount of air in the lungs after a Forceful expiration
c. F - It ranges between 1.3 L to 1.5 L
d. T - This is the definition for the Residual volume
e. F - Air inspired with a maximal inspiratory effort after a quite normal INSPIRATION is called inspiratory reserve volume.
02.
a. T
b. F - Not ventilated. Maximum amount of air that can be either inspired or expired in one breath. This includes Inspiratory reserve volume + Tidal volume + Expiratoyr reserve volume
c. F- residual capacity is the amount of air in the lungs after normal tidal expiration. That is 2.5 L
d. T
e. T
03.
a. T
b. F - Acconts for the difference in alvolar air and artirial P Co2
c. F - reduced as increased blood flow reduces areas of sluggish blood flow through lungs
d. F- This is anatomical dead space
e. T -Physiological dead space includes the anatomical dead space
04.
a. F
b. T - Due to increased fibrosis in the lungs
c. T
d. F - About 2.5 L
e. T
05.
a. F - Following tidal expiration
b. F - 2.5 L
c. T
d. T - Restrictive diseases increases FRC and Residual volume
e. T- Due to abdominal content is pushed towards the lung
06.
a. T
b. F
c. T
d. T
e. T - Due to fluid occupying air space
07.
a. F - Reduced
b. T
c. T
d. T
e. F - As alveolar air is trapped in asthma respiratory air has enough time for the diffusion,. Existing oxygen diffuses effectively
08.
a. T
b. T
c. F
d. T - Blood flow to the lung reduces
e. F - Reduces as anatomical dead space reduces.(Air way volume in Nose, Pharynx and larynx is reduced)
09.
a. F (30%)
b. F -Ventilation and Perfusion mismatch increases the physiological dead space
c. T
d. T - Reduced intra thoracic pressure expands the air way too
e. F - No difference
10.
a. F - This is useful in assessing obstructive lung diseases
b. F - Reduces
c. T
d. T
e. T - Normal FEV time is 4.5s, it increases in obstructive lung diseases in more than 5s
