Question

The patient is a 52 year old Caucasian female, born on March 16th. She is 5 foot 2 inches and weighs 110 lbs. See her Spirogram below.

Note: if the graph is between two lines then consider it half way between. So anything between 5.4 and 5.6 is 5.5. Don’t try and be more precise.

moderate reduction Normal reduction mild reduction Highlight- 1 Second Spirogram: 5.4 5.2 5.0 4.8 4.6 4.2 C) 3.8 2.8 2.6 2.4 2.2 2.0 1.8 1.6 1.4 1.2 1.0

Explanation / Answer

1. Forced Expiratory Volume 1 is the volume of first expiration in the first second - the volume associated with yellow rectangle in the graph.

FEV1 = 4.7- 2.7 = 2L

2. Inspiration capacity = tidal volume + inspiratory reserve volume, which, from the graph is

4.7 - 2.2 = 2.5L

Normal IC = 2.74 +- 0.59

Answer : Normal

3. Total lung capacity from the graph = 4.7 - 1 = 3.7L

Normal TLC = 5.25 +- 0.75

Answer : moderate reduction

4. Restrictive lung diseases show reduced TLC

Answer: restrictive lung disease

5. Moderate reduction
