Abstract
The present invention relates to a method and a system for controlling breathing of a patient. A mixing device extends from a patient interface to control a volume of exhaled gasses. The mixing device has a first orifice connected to and in fluid communication with a first control tube and terminating in a first variable flow control valve and a second orifice connected to and in fluid communication with a second control tube and terminating in a second variable flow control valve. Further a first volume extends between the first and second orifices. A controller then controls the volume of exhaled gasses from the patient using the first and second variable flow control valves.
Claims8
A method for controlling the breathing of a patient, said method comprising:
- applying a patient interface in communication with the patient's airway;
- providing a mixing device that extends from the patient interface, the mixing device comprising:
- a first orifice connected to and in fluid communication with a first control tube and terminating in a first variable flow control valve;
- a second orifice connected to and in fluid communication with a second control tube and terminating in a second variable flow control valve;
- a first volume extending between said first and second orifices;
- and
- monitoring exhaled gasses at an output of said first and second variable flow control valves via a controller;
- monitoring a process variable via the second control tube and adjusting the first control valve to increase or decrease the flow therethrough until the process variable returns to a predetermined range.
