Spirometer

The CMA Spirometer BT82i measures air flow rate during respiration in the range from -5 to 5 L/s. The sensor consists of a flow tube through which the air is inhaled and exhaled. To lessen the possibility of cross contamination between subjects the Spirometer is delivered with a disposable bacterial filter and 10 disposable mouthpieces. Replacement of a bacterial filter (CMA art. nr BT82fil) and mouthpieces (CMA art. nr BT82mp) can be ordered separately from CMA.

The spirometer is especially designed for measurements of flows and volumes of air in the lungs. It can be used to perform a variety of experiments:
• Recording breathing patterns before, during and after exercise
• Measuring important lung capacities like:
- Forced Expiratory Volume (FEV) - 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.
- Forced Vital Capacity (FVC) - the volume of air exhaled by a forced maximal exhalation after a full inhalation.
- Tidal Volume (TV) - the volume of air, inhaled and exhaled at rest.

The Spirometer can be directly connected to the analog BT inputs of the CMA interfaces.
Attention: The sensor cable BT - IEEE1394 needed to connect the sensor to an interface is not supplied with the sensor and has to be purchased separately (CMA Art. Nr BTsc_1).

Technical specifications of the sensor are described in its User's guide.
