What is the purpose of a cumulative timing device in fluoroscopy?

A cumulative timing device in fluoroscopy serves to indicate the total time that the fluoroscopy system has been in operation during a procedure. This capability is crucial for ensuring patient safety, as it helps radiologists and technicians keep track of the duration of fluoroscopic exposure. Prolonged exposure to fluoroscopy can lead to increased radiation doses, which could be harmful to patients. By providing a clear signal of the time elapsed, the device enables healthcare professionals to make informed decisions about when to pause or stop the procedure in order to minimize unnecessary radiation exposure.

Monitoring time spent under fluoroscopy is key in managing both safety protocols and patient care, as it encourages the practice of minimizing exposure while obtaining necessary diagnostic information.
