摘要： The piston ventilators include a double acting reciprocating piston, in which the piston motion delivering breathing gas to a patient receiving assistance from the ventilator simultaneously draws in breathing gas from a source of breathing gas, and a single acting piston ventilator, in which only the delivery end of the cylinder is provided with inlet and exhaust valves. In the double acting piston ventilator, breathing gas is supplied to both ends of the piston cylinder through two intake valves, and exhausting breathing gas through two exhaust valves. Both intake valves of the cylinder are ducted to the breathing gas supply, and the two exhaust valves of the cylinder are ducted to a gas delivery limb of the ventilator connected to the patient's airway.
