Which metrics are commonly monitored in medical telemetry?

• A. Heart rate, SpO2, blood pressure, respiration rate, temperature, ECG waveform; communication to clinicians.
• B. Vehicle speed, RPM, coolant temp.
• C. Atmospheric pressure, altitude, wind speed.
• D. Battery voltage, solar irradiance.

Answer: (A)

Medical telemetry focuses on watching a patient’s physiological status in real time, especially the heart and lungs. The metrics commonly monitored—heart rate, SpO2 (oxygen saturation), blood pressure, respiration rate, temperature, and the ECG waveform—cover the most medically meaningful signals: heart rate shows how fast the heart is beating; SpO2 indicates how well blood is oxygenated; blood pressure reflects blood flow to organs; respiration rate reveals breathing efficiency; temperature can signal infection or inflammatory processes; and the ECG waveform provides details about heart rhythm and electrical conduction. All of these data are typically transmitted to clinicians for continuous assessment and timely intervention.

The other options don’t fit medical telemetry: they reference vehicle performance, weather measurements, or power-system metrics, which pertain to entirely different domains and patient monitoring contexts.
