Precautions for using multi-function ECG monitor

1. Use 75% alcohol to clean the surface of the measurement site, the purpose is to remove the cuticle and sweat stains on the human skin to prevent poor contact of the electrode pads.

2. Be sure to connect the ground wire, which will play a very important role in the normal display of the waveform.

3. Choose the appropriate type of blood pressure cuff according to the patient's situation. It is different for adults, children and newborns. Cuffs of different specifications must be used. Here only adults are used as examples.

4. After the cuff is unfolded, it should be wrapped around the patient's elbow joint at 1-2 cm, and the degree of tightness should be such that it can be inserted into 1-2 fingers. Too loose may cause the pressure measurement to be too high; too tight may cause the pressure measurement to be low, at the same time it will make the patient uncomfortable and affect the blood pressure recovery of the patient's arm. The cuff catheter should be placed on the brachial artery, and the catheter should be on the extension of the middle finger.

5. The arm should be flush with the human heart, and the patient should be instructed not to talk or move when the blood pressure cuff is inflated.

6. The pressure measuring arm should not be used to measure body temperature at the same time, which will affect the accuracy of the body temperature value.

7. There should be no drip or malignant trauma, otherwise it will cause blood backflow or wound bleeding.

8. The patient's nails must not be too long, and must not have any stains, dirt, or onychomycosis.

9. The blood oxygen probe should be placed separately from the blood pressure measurement arm, because blood flow is blocked during blood pressure measurement, and the monitor manufacturer does not measure blood oxygen at this time, and the screen displays the word "blood oxygen probe off".

10. Generally choose lead II to observe and record heart rate and rhythm.
