Hme and compact breathing apparatus

An HME for use with a breathing apparatus to humidify air comprising:

• an inlet for coupling to a source of air, and an outlet for delivering air to a patient and an air flow path between them,
• HME material in the flow path, and exposed to the air flow path to exchange heat and moisture and/or humidity between patient air flow and an inlet air flow,
• wherein the HME material is sheet material with raised portions and is coiled, layered and/or stacked.

A compact breathing apparatus for providing flow or pressure to a patient, comprising:

• a housing with an inlet for receiving air and an outlet for providing airflow to a patient,
• a blower in the housing, the blower comprising an impeller coupled to a motor, wherein upon operation the blower rotates the impeller to draw air from the inlet and pass it to the outlet, and
• a flexible air inlet tube with an air inlet and an outlet coupled to the housing inlet wherein the flexible air inlet tube can be manipulated to position the air inlet away from occlusions when the compact breathing apparatus is placed in a convenient location.
