Abstract
A pressure generating system and method for generating a flow of fluid at a pressure above atmospheric pressure. The system includes a pressure generator and a valve that controls the pressure/flow of gas delivered to the patient. The system monitors energy provided to the valve, a characteristics associated with movement of the valve, a position of the valve, or any combination thereof. In addition, the controller controls an operating speed of the pressure generator such that the valve operates over a majority of the range of positions during use of the pressure support system.
Claims20
A pressure support system comprising:
- a pressure generator adapted to generate a flow of fluid at a pressure above atmospheric pressure;
- a conduit having a first end coupled to the output of the pressure generator and a second end;
- a valve operatively coupled to the conduit, wherein the valve is adapted to control a pressure of fluid delivered to the second end of the conduit and is operable over a range of positions;
- and
- a controller operatively coupled to the pressure generator and the valve, wherein the controller monitors energy provided to the valve, a characteristics associated with movement of the valve, a position of the valve, or any combination thereof, and wherein the controller controls an operating speed of the pressure generator such that the valve operates over a majority of the range of positions during use of the pressure support system.
A method of providing pressure support to a patient comprising:
- generating a flow of fluid at a pressure above atmospheric pressure via a pressure generator;
- providing the flow of fluid to a patient;
- controlling a pressure of the flow of fluid delivered to such a patient via a pressure control element that operates over a range of positions;
- and
- controlling an operating speed of the pressure generator such that the pressure control element over a majority of the range of positions during administration of a pressure support therapy.
A pressure support system comprising:
- a pressure generator adapted to generate a flow of fluid at a pressure above atmospheric pressure;
- a conduit having a first end coupled to the output of the pressure generator and a second end;
- a valve operatively coupled to the conduit and adapted to control a pressure of the flow of fluid delivered to such a patient;
- a controller operatively coupled to the valve and the pressure generator, wherein the controller controls the valve to deliver so that a pressure delivered to an airway of a patient corresponds to a set pressure, and wherein the controller controls an operating speed of the pressure generator to provide a pressure at an inlet of the valve at a level sufficient to deliver the set pressure.
