Respiratory gas conditioning, by which is meant the heating of the respiratory air to 37 °C with simultaneous humidification to almost 100 %, is one of the central issues in the ventilation of patients.

The use of humidification systems becomes necessary because the natural mechanisms (mouth, nose, pharynx and larynx) are largely bypassed by the tracheal cannula.


seleon developed a humidifier that simultaneously serves to humidify and warm the upper airway during invasive and non-invasive mechanical ventilation.


seleon developed two variants for invasive and non-invasive ventilation:

  1. The integrated variant is part of a system that includes the ventilator itself. All operation of the respiratory gas humidifier takes place via the ventilator.
  2. The stand-alone variant is an independent unit with its own operator interface, through which the setting of all parameters can be made. This variant of the humidifier has a serial interface and can be operated with almost all ventilators on the market.

With the development of a humidifier for different applications, seleon covers the entire range for the use of the devices. Taking into account the development of the associated tubing system and the humidifier for home use, customers can rely on seleon’s comprehensive know-how.
