1. A heart-lung machine system comprising:
an arterial pump;
a reservoir level detector system comprising two reservoir level detectors and by which a level of fluid in a reservoir is maintainable between the two reservoir level detectors;
a user interface; and
a central computer system configured to:
query the reservoir level detector system to determine whether the reservoir level detector system is active or inactive;
in response to determining that the reservoir level detector system is inactive, automatically activate the reservoir level detector system;
in response to the automatic activation of the reservoir level detector system:
(i) automatically generate an indication for display on the user interface that the reservoir level detector system is active, and
(ii) automatically prevent alarms related to detection of a lack of fluid by the reservoir level detector system from being generated; and
after the automatic prevention of the alarms related to the detection of the lack of fluid by the reservoir level detector system, discontinue the automatic prevention of the alarms in response to a first detection of fluid by the reservoir level detector system.
