Abstract
A fluid management system may include an inflow pump configured to pump fluid from a fluid supply source to a treatment site within a patient at a flow rate; and a controller configured to operate at a target flow rate in a flow control mode. In the flow control mode, the controller may be configured to maintain the target flow rate while monitoring a measured pressure communicated to the controller from a pressure sensor. When the measured pressure reaches a preset pressure threshold, the controller may be configured to automatically switch from the flow control mode to a pressure override mode in which the controller automatically reduces the flow rate below the target flow rate to return the measured pressure at or below the preset pressure threshold.
