Abstract
A respirator is described using pneumatic elements to generate a variety of operating modes. A gas mixture is passed through a patient connection which is coupled to supply the gas through a patient port to a patient. After passing the patient port the gas is controllably exhausted to atmosphere through an exhaust port in a control valve. The control valve regulates the closure of the exhaust port to provide inspiration and expiration control at the patient port. Pneumatic logic elements are combined to provide automatic inspiration and expiration support with different modes such as volume limited or pressure limited and with selection over the duration of the respective breathing phases. Various operating modes are obtained with variable restrictors selectively placed with the pneumatic logic elements.
