Called cardiac monitor, through the electrode sheet connected to the patient.
1, the green numbers represent the heart rate, the normal human heart rate is 60-100 times / min.
2. The blue numbers indicate the oxygen saturation level, which is normally above 95%.
3. The yellow numbers indicate the respiratory rate, with a normal range of 18-24 breaths/minute.
4, white figures generally indicated for blood pressure, systolic blood pressure normal range is 90-140, diastolic blood pressure normal range is 50-90, the unit is mmHg. such as: 110/85mmHg is normal blood pressure.

Precautions for ECG monitoring:
1. Take out the ECG lead wire, align the convex side of the lead wire plug with the groove of the ECG jack on the front panel of the main unit, and insert it.
2. The other end of the ECG leadwire with 5 electrodes is connected to the body being measured, and the steps for proper connection are:
(1) Clean the surface of the measurement site with 75% ethanol, in order to remove the stratum corneum and sweat stains on the human body's skin, and to prevent the electrodes from making poor contact.
(2) The electrode head of the ECG leadwire was fastened to the electrode clasps on the 5 electrode sheets.
(3) After the ethanol evaporated cleanly, the 5 electrode pieces were attached to the specific position after cleaning to make reliable contact without falling off.
(4) Clip the lapel clips on the lead wires to the hospital bed to secure them. And instruct the patient and health care workers not to pull and tug on the electrode wires and lead wires.
3. Be sure to connect the ground wire, which will play a very important role in the normal display of the waveform.
