Fluid management systems and methods of operating fluid management systems which may provide one or more functions associated with suction, irrigation, distention, deficit monitoring, infusion, fluid warming, and the like. Some example embodiments may include infra-red lamps arranged to heat fluid flowing through a disposable cartridge. Some example embodiments may provide a three-dimensional fluid path through the cartridge and/or multi-stage heating capabilities. Some example fluid management systems may be selectable between pressure control and flow control modes.

1. A fluid management system comprising: a pump configured to deliver a fluid from at least one fluid supply container to a site, said site being a surgical site or a patient;a heater assembly for heating the fluid prior to delivery of the fluid to the site; anda control system for operating the fluid management system according to operating parameters, said control system including a user interface for a user to select a plurality of default operating parameters associated with delivery of the fluid to the site, wherein said plurality of default operating parameters include: establishment of either a pressure control mode or a flow control mode, wherein for the pressure control mode a default target pressure is established to control the pump to deliver fluid to the site, and wherein for the flow control mode a default target flow rate is established to control the pump to deliver fluid to the site,enablement or disablement of the heater assembly to heat the fluid, wherein if the heater assembly is enabled, then a default target temperature is established for heating the fluid delivered to the site according to the target temperature, andenablement or disablement of fluid deficit monitoring for determining a fluid deficit that is a difference between (i) a volume of fluid delivered to the site from the at least one fluid supply container and (ii) a volume of fluid returned from the site to at least one fluid collection container, wherein if the fluid deficit monitoring is enabled, then a default alarm limit is established that is indicative of a maximum fluid deficit, said control system activating a deficit alarm when the monitored fluid deficit exceeds the maximum fluid deficit. 2. The fluid management system of claim 1, wherein establishment of the pressure control mode includes establishment of a default pressure alarm setpoint indicative of a maximum pressure, said control system activating an alarm when a monitored pressure exceeds the maximum pressure. 3. The fluid management system of claim 1, wherein said user interface further comprises a temperature selection for adjusting said target temperature within a predetermined temperature range. 4. The fluid management system of claim 1, wherein said control system adjusts the heater assembly to maintain the temperature of the fluid delivered to the site according to the target temperature based on at least (i) an inlet fluid temperature and (ii) a current flow rate of the fluid. 5. The fluid management system of claim 1, wherein said user interface further comprises a heater selection for enabling and disabling the heater assembly. 6. The fluid management system of claim 1, wherein said user interface further comprises a pressure selection for adjusting the target pressure within a predetermined pressure range. 7. The fluid management system of claim 1, wherein said user interface further comprises a flow rate selection for adjusting the target flow rate within a predetermined flow rate range. 8. The fluid management system of claim 1, wherein said control system adjusts a speed of the pump to maintain delivery of the fluid to the site at approximately the target flow rate. 9. The fluid management system of claim 1, wherein said control system adjusts a speed of the pump to maintain delivery of the fluid to the site at approximately the target pressure. 10. The fluid management system of claim 1, wherein said user interface further comprises a deficit alarm limit selection for adjusting the deficit alarm limit within a predetermined range. 11. The fluid management system of claim 1, wherein said user interface further comprises a deficit monitoring selection for enabling and disabling the fluid deficit monitoring. 12. The fluid management system of claim 1, wherein said plurality of default operating parameters further includes: a default perforation alarm limit indicative of a maximum rate of change of said fluid deficit, said control system activating a perforation alarm when the rate of change of said fluid deficit exceeds the maximum rate of change of said fluid deficit. 13. The fluid management system of claim 12, wherein said user interface further comprises a perforation alarm limit selection for adjusting the perforation alarm limit within a predetermined range. 14. The fluid management system of claim 1, wherein said fluid management system further comprises: at least one load cell for generating a first electrical signal indicative of a weight of the at least one fluid supply container; andat least one load cell configured to generate a second electrical signal associated with a weight of the at least one fluid collection container,wherein said control system determines a fluid deficit using the first and second electrical signals by calculating a difference between (1) an initial total system weight including an initial weight of the at least one fluid supply container and an initial weight of the at least one fluid collection container and (2) a current total system weight including a current weight of the at least one fluid supply container and a current weight of the at least one fluid collection container. 15. The fluid management system of claim 1, wherein said user interface includes selection options for enablement or disablement of one or more of the following: fluid deficit monitoring to monitor a fluid deficit associated with delivery of the fluid to the site and return of the fluid from the site;perforation alarm to monitor rate of change of said fluid deficit; andfluid warming to heat the fluid delivered to the site. 16. The fluid management system of claim 1, wherein said user interface presents a plurality of medical procedures involving delivery of the fluid to the site using the fluid management system, wherein selection of one of the plurality of medical procedures selects the plurality of default operating parameters associated with delivery of the fluid to the site.
