Abstract: A temporary patient ventilator is a modified version of the widely used air-mask-bag-unit (AMBU). The modified AMBU has guy wires attached to the inside resilient walls of the airbag which are pulled to collapse the airbag. A drive is used to alternately pull on the guy wires and then release them automatically. This new automated airbag unit system allows hands free operation of the ventilation device for short periods of time. The drive has rechargeable batteries so that the temporary ventilator is completely mobile.
