What is the function of telemetry in medical devices?

Telemetry in medical devices primarily refers to the remote transmission of physiological data from patients to healthcare providers. This technology allows medical practitioners to monitor patients' vital signs, such as heart rate, blood pressure, and oxygen levels, in real-time from a distance. By transmitting this data wirelessly to a central monitoring system, telemetry enables timely medical interventions and continuous observation without the need for patients to be physically present in a healthcare facility.

This capability is especially crucial in scenarios involving patients in critical care or those with chronic conditions who require regular monitoring. The real-time data transmission aids in making informed decisions quickly, enhances patient safety, and improves overall healthcare management.

Other functions like providing a backup power source, controlling operational modes of devices, or calibrating equipment settings do not relate directly to the primary purpose of telemetry, which is focused on data communication and monitoring.
