Abstract
In various embodiments, a pneumatic system valve for a surgical console may be controlled by a controller configured to adjust a valve duty cycle (VDC) of the valve to reduce a difference between the valve's differential pressure and a desired differential pressure. In some embodiments, average differential pressures may be detected and relayed from a pressure sensor, coupled to one or more ports of the valve, to the controller. The controller may compare the measured average differential pressure against the desired average differential pressure (e.g., received from the user). The controller may then determine a modified VDC to reduce a difference between the desired average differential pressure and the measured average differential pressure. In some embodiments, the desired average differential pressure may be determined based on input received from a user of the surgical console.
