Abstract:

A ventilator system is presented. The ventilator system includes a controller configured to generate a first control signal for a first time-period and a second control signal for a second time-period during an inspiration time. Also, the ventilator system includes a rotary pump configured to change one of a pressure and a flow rate of the drive gas to a first value if the first control signal is received and change the one of the pressure and the flow rate of the drive gas to a second value if the second control signal is received. Further, the rotary pump is configured to deliver the drive gas to cause supply of a medical gas during the inspiration time, wherein the medical gas is supplied based on the one of the pressure and the flow rate of the drive gas delivered from the rotary pump.
