Exam 1 Pulmonary function test
questions and correct answers
What is the most common pulmonary function test? CORRECT ANSWERS Spirometry
and its becoming more available
what does spirometry measure? CORRECT ANSWERS Volume
Velocity of air that can be inhaled and
exhaled from a patient's lungs.
Whats the information from spirometry used for? CORRECT ANSWERS To diagnose
various pulmonary conditions.
What causes PFT results to vary and are required for accurate spirometry
interpretation? CORRECT ANSWERS ○ Age
○ Gender
○ Height
○ Weight
○ Race
Waht are indications for spirometry? CORRECT ANSWERS Indications ● Detecting
pulmonary disease
○ Evaluation of dyspnea ○ Chronic phlegm production ○ Cyanosis ○ Finger clubbing ○
Abnormal ABGs or CXR
● Assessing severity or
progression of known disease ● Risk stratification of patients
for certain surgeries
○ Cardiothoracic procedures ○ Others if pulmonary disease
What are contraindicaitons for spirometry? CORRECT ANSWERS ● Acute disorders
affecting test
performance (vomiting, etc)
● Hemoptysis
● Pneumothorax
● Recent cardiothoracic or
abdominal surgery
● Recent eye surgery (increases IOP during spirometry)
● Recent MI or unstable angina
● Known thoracic aneurysm
What are 4 examples of lung volume measurements? CORRECT ANSWERS ○
Expiratory Reserve Volume (ERV)
○ Inspiratory Reserve Volume (IRV)
○ Residual Volume (RV)
, ○ Tidal Volume (TV or VT)
What are 4 examples of lung capacity measurements? CORRECT ANSWERS ○
Functional Residual Capacity (FRC)
○ Inspiratory Capacity (IC)
○ Total Lung Capacity (TLC)
○ Vital Capacity (VC)
tidal volume graph CORRECT ANSWERS
What is the Tidal Volume? CORRECT ANSWERS Total volume of air
inhaled or exhaled
during each relaxed
respiration cycle.
What is the inspiratory reserve volume? CORRECT ANSWERS the
maximal volume of air
inhaled above normal
inspiration.
Whats The Inspiratory
Capacity? CORRECT ANSWERS The maximal volume of air that can be inhaled above
resting
exhalation.
○ Tidal Volume +
Inspiratory
Reserve Volume
Whats The Expiratory Reserve Volume (ERV)? CORRECT ANSWERS the
maximal volume of air
that can be exhaled
below end-respiratory
expiration.
○ Opposite of IRV
Whats TheVital Capacity (VC)? CORRECT ANSWERS the largest volume of
air measured on
completed exhalation
after full inspiration.
○ Forced Vital
Capacity is one of
the key spirometry
measurements
Whats The Residual Volume (RV)? CORRECT ANSWERS The amount of air
remaining in the
