1. A fluid management and medical device 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:
an inflow pump configured to pump fluid from a fluid supply source to the treatment site; and
a controller configured to calculate a fluid deficit when the distal end of the elongate shaft is disposed within the patient;
wherein the controller is configured to automatically pause fluid deficit calculation when the distal end of the elongate shaft is removed from the patient.
