Abstract
An exhalation system for connection in the exhalation path of a ventilator for assisting a patient's breathing includes a heated bacteria filter for heating exhaled gas passing through it to a temperature high enough to substantially avoid condensation in the filter. A connecting passageway on the downstream side of the filter for connection to a monitoring device is also heated along at least part of its length to add additional heat to the gas passing through it so that condensation in the connecting passageway and monitoring device is substantially avoided.
