Spirometer

The spirometer 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.

Technical specifications:

Measurement range: -5 to +5 L/s
Resolution: 0.01 L/s
Maximum measurement frequency: 100 kHz (CoachLab II+, WiLab) / 1 MHz (VinciLab 2)
Warranty: 3 years

All technical specifications of the spirometer sensor are described in the product manual, see downloads.

The spirometer 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.

A ‘P4272-1K BT sensor cable, single’ is required to connect the sensor to the interface.
Please check whether you already have this cable in your stock.
