Abstract:
1. A surgical console, comprising: a pneumatic valve; at least a first port and a second port coupled to the valve, wherein the valve is configured to provide pressurized gas alternately to each of the first port and the second port; at least one pressure sensor coupled to at least one of the first port and the second port; and a controller coupled to the valve and the at least one pressure sensor, wherein the controller is operable to control valve channel open and close times according to a valve duty cycle; wherein the controller is configured to receive pressure data from the at least one pressure sensor; wherein the controller is configured to modify the valve duty cycle based on the received pressure data; wherein the controller is configured to receive pressure data from the at least one pressure sensor to use in determining a measured differential pressure between the first port and the second port and wherein the controller is configured to modify the valve duty cycle based on a difference between the measured differential pressure and a desired average differential pressure.
