Spirometer
(Order Code SPR-BTA)
The Spirometer can be used to perform a
variety of experiments related to air flow
and lung volume. The sensor handle can
be held manually, or it can be attached
to a tripod or stand using the threaded insert in the bottom of the handle. The
sensor is composed of a removable Flow Head for easy cleaning and
sterilization and a differential pressure transducer. The Spirometer can be used to
perform a variety of tests, including:
l
FEV (forced expiratory volume). FEV is the volume of air exhaled after a
short period of constant effort. When this test is done over a one-second
interval, it is known as FEV1.
l
FVC (forced vital capacity). FVC is the volume of air exhaled by a forced
maximal exhalation after a full inhalation.
l
TV (tidal volume). TV is the volume of air inhaled and exhaled at rest.
