Body Plethysmograph

The device ensures the measurement of mechanical parameters of the pulmonary system. It is accessible to patients who are seated in a wheelchair (optional). The cabin's double time constant enables tests to be conducted at normal breathing frequency and with panting. Additionally, the device offers a diffusion capacity test (optional).
A spacious cabin with a roof made of hardened glass and four transparent walls.
There is no moving component in the electro-magnetic door lock.Audiovisual metronome that can be programmed

The BTPS is automatically corrected based on the temperature, humidity, and pressure measurements in the cabin.Full automatic calibration and leakage testing
