<p>A respirator is described wherein a plurality of pneumatic bistable elements are employed in an automatically operated pneumatic circuit. A constant inspiratory to expiratory ratio pneumatic circuit is provided to simplify respirator control. A demand sensing circuit interrupts an oscillator to commence an inspiratory phase in response to pressure changes introduced in a patient gas supply circuit. A manual control is provided to enable manual dispensing of respiratory support. A pneumatic circuit is provided for generating an end inspiratory plateau period. During this period gas equilibration in different compartments of the lung is permitted and in addition a measurement of peak intraalveolar pressure is made.</p> |
