While performing postural drainage and percussion, the
respiratory therapist palpates subcutaneous emphy- sema in the
patient. The therapist should postpone the therapy and
recommend which of the following?
A. Measure ABG levels
B. Initiate IPPB therapy
C. Obtain a chest radiograph
D. Perform bedside spirometry - ANSWER-C,
Air leaking from the lung often finds its way into the
subcutaneous tissues. It is common after a tracheotomy is
done to observe subcutaneous emphysema in the neck area.
Observing subcutaneous emphysema indicates a pulmonary
air leak, and a pneumothorax should be suspected. A chest
film should be ordered for confirmation while the therapist
assesses the patient for asymmetrical chest movement,
tracheal deviation, diminished breath sounds, tachycardia,
tachypnea, and SpO2value.

A patient's PaO2 increases after mechanical ventila- tion is
initiated at 21% O2. What accounts for the improved oxygenation
status?
1. Increased distribution of ventilation
2. Increased VD/VT ratio
3. Decreased venous return to the heart
4. Increased P(A-a)O2 gradient
A. 1 only
B. 1 and 4 only
C. 1, 2, and 3 only
D. 1, 3, and 4 only - ANSWER-A,
Even with room air, positive pressure to the lungs will
increase PaO2 as a result of increased distribution of
ventilation. Positive pressure ventilation will increase the
diameter of the alveoli, which will provide a larger surface
area for the diffusion of gases at the alveolar-capillary
membrane. This will decrease P(A-a)O2 and VD/VT.

A V/Q scan is conducted on a patient in whom pulmonary
embolism is suspected. The scan shows normal ventilation and
the absence of perfusion in the left upper lobe. The respiratory
therapist should estimate the V/Q ratio in this area to be which of
the following?
A. Less than 0.5
B. 0.8
C. 1.0
D. More than 2.0 - ANSWER-D,
To determine the V/Q ratio, divide ventilation (represented by
the numerator) by perfusion (represented by the
denominator). Normal alveolar ventilation is approximately 4
L/min, and an average pulmonary blood flow is about 5
L/min. Divide ventilation by perfusion (4/5); the result is a 0.8
V/Q ratio. In a healthy individual in the upright position, the
upper portion of the lung receives greater ventilation than
perfusion and therefore has an increased V/Q ratio (more
than 0.8). Perfusion is greater than ventilation in the lower
portions of the lung as a result of gravity; therefore the V/Q
ratio is decreased (less than 0.8) in those areas. In this
question, perfusion is decreased while ventilation remains
normal; therefore the V/Q ratio is increased (more than 0.8).

Since there is no perfusion to that lung, the ration would be
very high, more than the 1.0. This is a classic example of a
pulmonary embolism, in which pulmonary blood flow is
obstructed while ventilation remains normal. (Application)
The following data are collected from a patient receiving volume-
controlled ventilation:
PEEP level PaO2 PVO2 VT
6cmH2O 64 35 all 600
8cmH2O 70 38
10 cm H2O 75 43
12 cm H2O 80 34
Which of the following represents optimal PEEP?
A. 6 cm H2O
B. 8 cm H2O
C. 10 cm H2O
D. 12 cm H2O - ANSWER-C,
