2, calibration temperature: use a thermometer with a known accurate temperature, place it in the same environment as the temperature sensor on the monitoring instrument, compare the temperature readings of the two, and calibrate accordingly on the monitoring instrument.
3. Calibrate blood pressure: Use a sphygmomanometer of known accuracy and compare it to the blood pressure sensor on the monitoring device. This can be done by connecting both the sphygmomanometer and the monitoring instrument to the same patient and then comparing the blood pressure readings one by one and calibrating them accordingly on the monitoring instrument.
4. Calibrate pulse oximetry: Using a pulse oximetry instrument of known accuracy, compare it to the SpO2 sensor on the monitoring instrument. Connect the instrument to the same patient, compare SpO2 readings one by one, and calibrate accordingly on the monitoring instrument.
5. Calibrate heart rate: Compare the heart rate sensor on the monitoring instrument to a device with a known accurate heart rate, such as an ECG device or a manual pulse count. Compare the two and calibrate accordingly on the monitoring instrument.
