Introduction To Spirometry - Welch Allyn PneumoCheck Operating Instructions Manual

INTRODUCTION TO SPIROMETRY

The Welch Allyn PneumoCheck is a hand-held spirometer specifi-
cally designed to perform FVC and MVV spirometry tests easily and
accurately. In order to properly use your PneumoCheck and to obtain
useful test results, you should be familiar with the basic principles of
spirometry:
A spirometer is a device that measures the amount of air that is
breathed into or out of it.
To perform a spirometry test, a patient breathes into the spirometer
in a prescribed manner over a known period of time. Several differ-
ent types of spirometry tests can be done using a spirometer, each
of which yields different information about the patient's lung function.
