Abstract
A medical ventilator includes a pressure generator for increasing a pressure of gas that produces heat during the operation thereof. A heat sink spaced from the pressure generator is provided for absorbing heat from the pressure generator. A bacteria filter requiring heating in excess of an ambient temperature for the effective operation thereof is coupled in thermal communication with the heat sink. A heat pipe is coupled in thermal communication with the heat sink and the pressure generator for conveying at least part of heat produced by the pressure generator to the bacteria filter via the heat sink.
