Medical device audible alerts

Abstract

A method for controlling a medical device. The method includes providing a conduit coupled to a pump, the pump configured to selectively provide a pressure in the conduit, a motor configured to selectively drive the pump at an operating frequency to provide the pressure in the conduit, and a controller configured to selectively drive the motor and monitor the medical device. The method includes selectively driving the motor at an indicating frequency that is different from the operating frequency when the controller identifies a value outside of a threshold for the medical device. The indicating frequency produces an indicating audible or haptic feedback that is greater than an operating audible or haptic feedback provided at the operating frequency.
