Question
Chapter 10, Problem 1CAQ5
Summary Introduction
To review:
The way through which decreased pulmonary diffusion and decreased lung compliance are manifested in the clinical setting.
Introduction:
The diffusion capacity is also known as the transfer factor. It can be defined as the measure of the transfer of gas in the lung to the red blood cells. It is one of the pulmonary function tests. Pulmonary compliance is a measure of the ability of the lung to stretch. In other terms, it can be defined as the distensibility of elastic tissue.
Please refer to Clinical Application Case-1 for further information.

Clinical terms for variations in respiratory rhythm are listed in the boxes below. Place each term in the proper location to identify the
combination of factors (e.g. volume and rate) that characterizes each condition.

Volume of breathing
Using the following lung volumes, calculate this persons FEV1 / FVC ratio. What this person's pulmonary function be clinically classified: normal, obstructive, or restricted?
TLC = 5.2 L
FVC = 3.8
TV = 0.5 L
ERV = 1.1 L
IRV = 2.2 L
This person forcefully expired 2.4 L in one second. according to reference material, normal VC for this person is 3.6 L.
You would expect an individual with emphysema to demonstrate which of the following?
1. lowered arterial pH (more acidic arterial blood)
2. lowered arterial dissolved oxygen (less oxygen dissolved in the plasma - low PO2 value)
3. higher lung compliance
4. lowered FEV1/FVC ratio or percentage
Choose from the following:
(A) 1 only
(B) 1 and 2
(C) 2 and 3
(D) 2 and 4
(E) 3 and 4
(F) 1, 3 and 4
(G) 1, 2, 3, and 4
