Chapter 1; Basic Terms and Concepts of Mechanical Ventilation
MULTIPLE CHOICE
1. The body’s mechanism for conducting air in and out of the lungs is known as
which of the following?
a. External respiration
b. Internal respiration
c. Spontaneous ventilation
d. Mechanical ventilation
ANSWER: C
The conduction of air in and out of the body is known as ventilation. Since the
question asks for the body’s mechanism, this would be spontaneous
ventilation. External respiration involves the exchange of oxygen (O 2) and
carbon dioxide (CO 2) between the alveoli and the pulmonary capillaries.
Internal respiration occurs at the cellular level and involves movement of
oxygen from the systemic blood into the cells.
DIF: 1 REF: pg. 3
2. Which of the following are involved in external respiration?
a. Red blood cells and body cells
b. Scalenes and trapezius
muscles
c. Alveoli and pulmonary
capillaries
d. External oblique and
transverse abdominal muscles
ANSWER: C

External respiration involves the exchange of oxygen and carbon dioxide
(CO2) between the alveoli and the pulmonary capillaries. Internal respiration
occurs at the cellular level and involves movement of oxygen from the
systemic blood into the cells.
Scalene and trapezius muscles are accessory muscles of inspiration. External
oblique and transverse abdominal muscles are accessory muscles of
expiration.

3. The graph that shows intrapleural pressure changes during normal
spontaneous breathing is depicted by which of the following?
a.
b.
c.
d.
ANSWER: B
During spontaneous breathing the intrapleural pressure drops from about -
5 cm H2O at end-expiration to about -10 cm H2O at end-inspiration. The
graph depicted for answer B shows that change from -5 cm H 2O to -10 cm
H2O.
DIF: 1 REF: pg. 4
4. During spontaneous inspiration alveolar pressure (P A) is about:
.
a. - 1 cm H2O
b. + 1 cm H2O
c. 0 cm H2O
d. 5 cm H2O
ANSWER: A
-1 cm H2O is the lowest alveolar pressure will become during normal

spontaneous ventilation. During the exhalation of a normal spontaneous
breath the alveolar pressure will become +1 cm H 2O.
DIF: 1 REF: pg. 3
5. The pressure required to maintain alveolar inflation is known as which of
the following?
a. Transairway pressure (P TA )
b. Transthoracic pressure (PTT)
c. Transrespiratory pressure (P TR)
d. Transpulmonary pressure (PL)
ANSWER: D
The definition of transpulmonary pressure (P L) is the pressure required to
maintain alveolar inflation. Transairway pressure (P TA ) is the pressure
gradient required to produce airflow in the conducting tubes. Transrespiratory
pressure (P TR) is the pressure to inflate the lungs and airways during positive
pressure ventilation. Transthoracic pressure (P TT) represents the pressure
required to expand or contract the lungs and the chest wall at the same time.
DIF: 1 REF: pg. 3
6. Calculate the pressure needed to overcome airway resistance during positive
pressure ventilation when the proximal airway pressure (P Aw ) is 35 cm H2O
and the alveolar pressure (P A) is 5 cm H2O.
a. 7 cm H2O
b. 30 cm H2O
c. 40 cm H2O
d. 175 cm H2O
ANSWER: B
The trans airway pressure (P TA ) is used to calculate the pressure required to
overcome airway resistance during mechanical ventilation. This formula is
