Strict requirements are imposed on the development of an air humidifier for home ventilation: adequate warming and humidification of the breathing air while simultaneously preventing possible condensation of the humidified air in the ventilation hose. Operation and handling by the patient in the home environment imposes special requirements for the usability and cleaning of the system.
In addition to breathing air conditioning, ease of use and straightforward cleaning of the system play a crucial role in home ventilation. A simple layout with the fewest possible components is especially important here.
Possible error sources in operation are identified and eliminated in a timely manner with the help of prototype studies on test subjects. Breathing air conditioning (the warming of breathing air to 37 °C with simultaneous humidification to nearly 100%) is among the key issues in patient ventilation.
