The Alpha 300 is a respiratory therapy device with a compressor that allows periodic aerosol inhalation.

The Alpha 302 works with an oxygen connection.  The Alpha 301 works with central compressed air and oxygen connection.

The Alpha 301 and Alpha 302 devices are respiratory therapy devices that allow periodic aerosol inhalation (such as a physiological saline solution for respiratory gas humidification) in combination with assisted, intermittend pressure support (IPPB).

The Alpha 301 and 302 offers the possibility to enrich the breathing air with oxygen.
