Abstract
A method, apparatus, and computer program product are provided for monitoring a volume of fluid in a flexible fluid bag. A flexible fluid bag according to the invention may include a first and second side wall opposing each other, an outlet through which fluid contained in the fluid bag is evacuated, a signaling tag carried by the first side wall, and an inducer carried by the second side wall. The signaling tag and inducer may be positioned such that when a volume of fluid in the fluid bag is less than a predefined threshold, the signaling tag and inducer come into sufficient proximity due to flexation of at least a portion of the sidewalls of the fluid bag as fluid is evacuated from the fluid bag to trigger a state of a signal emitted by the signaling tag to change.
