Abstract

A ventilator system includes a mask to be placed over a wearer'"'"'s face. The mask has a shell. The ventilator shell further includes a cushion provided to the shell to sealingly connect the mask to the wearer'"'"'s face and thereby form a chamber between the shell and the wearer'"'"'s face. The ventilator system also includes an inlet port in the shell and an air flow generator. The inlet port is configured to receive a flow of breathable gas. The air flow generator is mounted on the mask and is capable of creating a pressure of about 2-40 cm H₂O in the chamber.

Claims
