Pulmonary Function Test Procedure
1. Use a nose clip or have the test
subject hold his or her nose to
ensure that all breathing is
done through the mouth.
2. Hold the mouthpiece of the
Spirometer stationary and
away from air currents
(including expired air). Start
data collection; note the
flashing red WAIT indicator on
the sensor. Wait until the green
READY indicator is
illuminated before you move
the mouthpiece or expose it to
air currents.
3. After the green READY
indicator has illuminated, place
the tapered end of the
mouthpiece between the test
subjects’s front teeth with the
lips creating a seal to ensure
that all inspired and expired air
flows through the mouthpiece.
4. Have the test subject perform
the following sequence of
breathing:
5. Stop data collection.
• Breathe quietly for about four breaths.
• Perform a forced inspiration followed immediately
by a maximum-effort forced expiration.*
• Breath quietly for two breaths.
