To know about
1. Major and minor hardwares of power lab.
2. Softwares of Power lab.
3. Features in the Lab Tutor software
4. Spirometer and its uses.
23. Spirometer pod
(Zero Pod)
• The Spirometer Pod is ideal for teaching, which
provides entry level human respiratory flow
measurements using an appropriate respiratory
flow head and PowerLab data acquisition
system.
25. Features:
• 1. Low Noise
• 2. Low air flow resolution
• 3. Temperature sensitive

Zeroing the Zero Pod
l. In order to give appropriate volume
measurements it is important to always
reset the baseline by clicking the ‘Zero Pod
button’ prior to making any new recording.
Note: The Zero Pod button resets the voltage offset from the Spirometer Pod
to zero. It should be clicked prior to starting any recording during the
Respiratory Air Flow and Volume experiment.
27. • 2. Since the Spirometer Pod is sensitive to
temperature and tends to drift during warm-
up, turn on the PowerLab for at least 5 minutes
before use.
• To prevent temperature drift due to heating of
the Pod, place it on a shelf or beside the
PowerLab, away from the PowerLab power
supply.

28. How to prevent vaporization in
plastic tubes?
“In order to prevent
water vapor
collecting in the two
plastic tubes from
the flow head they
should always be
pointing upwards”
29. Indications of Spirometer
• Restrictive or chronic obstructive lung disease
• Airway resistance
• Pulmonary function
