Historical information

The Dräeger Pulmotor was developed in 1907. It addressed previous concerns about lung injury, by limiting both the inspiratory and expiratory pressures. Although still controversial, the Pulmotor was widely distributed and commercially successful. Oxygen from cylinders provided both the inspiratory gas flow and the driving mechanism. Expiration was an active process and gases were sucked from the lungs by negative pressure created by a Venturi effect. This device came with a facemask and harness, with a caution that the operator should take care to prevent air entering the stomach.
