2. Respiratory gas humidification - Wikipedia

   en.wikipedia.org/wiki/Respiratory_gas_humidification

   Respiratory gas humidification is a method of artificially conditioning respiratory gas for the patient during therapy, and involves humidification, warming, and occasionally filtration of the gas being delivered. If these three measures are not performed to compensate for the natural conditioning of air by the respiratory system, lung ...

3. Heated humidified high-flow therapy - Wikipedia

   en.wikipedia.org/wiki/Heated_humidified_high...

   The higher the flow, the more important proper humidification and heating of the flow becomes to prevent tissue irritation and mucous drying. It has been found that long term use of flows of 20-25 L/min can help reduce symptoms of chronic obstructive pulmonary disease. This is because, heat and humidity help mucociliary clearance.

4. Heat and moisture exchanger - Wikipedia

   en.wikipedia.org/wiki/Heat_and_Moisture_Exchanger

   Humidification and suctioning are necessary to manage secretions in patients on mechanical ventilation. According to Branson (2007), the optimal humidification level "has been not well defined, but it is clear that in a patient with thick and copious secretions a heated humidifier is preferred to an HME". [3]

5. Heating, ventilation, and air conditioning - Wikipedia

   en.wikipedia.org/wiki/Heating,_ventilation,_and...

   Ventilation on the downdraught system, by impulsion, or the 'plenum' principle, applied to schoolrooms (1899) Natural ventilation is the ventilation of a building with outside air without using fans or other mechanical systems. It can be via operable windows, louvers, or trickle vents when spaces are small and the architecture permits.

6. Heat recovery ventilation - Wikipedia

   en.wikipedia.org/wiki/Heat_recovery_ventilation

   Ventilation unit with heat pump & ground heat exchanger - cooling. Heat recovery ventilation (HRV), also known as mechanical ventilation heat recovery (MVHR) is a ventilation system that recovers energy by operating between two air sources at different temperatures. It is used to reduce the heating and cooling demands of buildings.

7. Humidifier - Wikipedia

   en.wikipedia.org/wiki/Humidifier

   Water evaporation even when humidification is not required (due to the pan of water which remains exposed to a high velocity air stream) Mold growth in the pan full of water (this problem is exacerbated by the large quantity of air, inevitably carrying mold spores, passing through the humidifier whether in use or not).

9. Air handler - Wikipedia

   en.wikipedia.org/wiki/Air_handler

   Humidification is often necessary in colder climates where continuous heating will make the air drier, resulting in uncomfortable air quality and increased static electricity. Various types of humidification may be used: Evaporative: dry air blown over a reservoir will evaporate some of the water. The rate of evaporation can be increased by ...
