A pulmonary resuscitator is set forth of the type having a compressible bladder to be depressed to supply air to a mask. Both the compressible bladder and mask have integral therewith a network of inflatable tubes which when pressurized resiliently rigidify the bladder and mask to establish nominal erected bladder and mask shapes. The bladder has an inlet check valve and the mask has an outlet check valve where the outlet check valve utilizes a flapper valve for permitting flow of fluid into the mask upon depression of the bladder. Exhaust ports are located adjacent the flapper valve and are closed by the flapper valve when the bladder is depressed. The exhaust ports are opened when the flapper valve closes as the bladder returns to its nominal shape after being depressed. An air spring contained within the bladder chamber is in fluid communication with the network of inflatable tubes and through limiting orifices controls the rate at which the bladder returns to its nominal shape after depression.
