1. An automated fluid management system, comprising:
a medical device comprising:
an elongate shaft configured to access a treatment site within a patient;
one or more sensors proximate a distal end of the elongate shaft; and
a handle coupled to a proximal end of the elongate shaft; and
a fluid management system comprising:
a first fluid supply source in fluid communication with the elongate shaft;
a second fluid supply source;
a collection container in fluid communication with the elongate shaft;
an inflow pump configured to pump fluid from the first fluid supply source to the treatment site; and
a controller configured to set a total fluid deficit to zero after priming the fluid management system;
wherein the controller is configured to automatically begin calculating a first fluid deficit associated with the first fluid supply source when the distal end of the elongate shaft is disposed within the patient;
wherein the controller is configured to retain the first fluid deficit when the first fluid supply source is replaced with the second fluid supply source in fluid communication with the elongate shaft, and the controller is configured to thereafter calculate the total fluid deficit by adding the first fluid deficit and a second fluid deficit associated with the second fluid supply source when the distal end of the elongate shaft is disposed within the patient.
