Humidification and the HME filter
The process of intubation and ventilation bypasses both the physiological humidification system and protective filtering processes. Various devices have been developed to aid in providing humidification of medical gasses and to serve as filters to reduce transmission of microbes. The following types of devices are available:
- Heat and moisture exchanger without filter (HME)
- Electrostatic filter with or without HME
- Pleated filter with or without HME
