What is a primary function of telemetry in monitoring systems?

Telemetry plays a crucial role in monitoring systems by enabling the transfer of data from patients to healthcare professionals in real-time. This function is essential for remote patient care, allowing medical staff to continuously monitor vital signs and other health metrics without being physically present. By utilizing telemetry, clinicians can quickly assess a patient's condition, respond to changes instantaneously, and make informed decisions regarding treatment.

The ability to provide real-time feedback is particularly vital in critical care settings, where timely interventions can significantly improve patient outcomes. It illustrates how technology enhances healthcare delivery, especially for patients who are not in a traditional clinical setting.

The other options, while they may relate to various aspects of healthcare or monitoring, do not capture the primary function of telemetry as effectively. For instance, managing inventory addresses logistical concerns, reducing costs speaks to economic factors rather than the core purpose of telemetry, and increasing the frequency of checks pertains to procedural aspects that are not inherently tied to the real-time capabilities that telemetry provides.
