Operation Method and Procedure of Electrocardiographic Monitor

Generally, an electrocardiographic (ECG) monitor is a medical device used in hospitals to monitor vital signs such as the patient's respiration, pulse, blood pressure, heart rate, and blood oxygen saturation. The specific operating procedures are as follows:

1. Prepare the ECG monitor. Have the patient lie flat or semi-reclined on the bed, and examine the skin condition of the patient's chest area, arms, and fingers.

2. Connect the device to a power source. After turning it on, check the machine's functions.

3. Turn on the main switch to start the device. Wipe the areas where electrodes will be attached with cotton balls moistened with normal saline or alcohol, then attach the electrode patches.

4. Place the RA electrode at the first intercostal space along the right mid-clavicular line; place LA at the left mid-clavicular line; RL at the right mid-clavicular line level with the xiphoid process; LL at the left mid-clavicular line level with the xiphoid process; and C at the fourth intercostal space along the left sternal border.

5. Wrap the blood pressure cuff around the patient’s upper arm at the same level as the heart, adjusting it to the appropriate tightness.

6. Attach the blood oxygen saturation probe (pulse oximeter) to the patient’s finger—typically the index, middle, or ring finger. Insert the finger into the probe chamber with the fingernail surface facing upward.

7. After connecting all monitoring devices, check whether the display screen shows readings normally and verify if any data appear abnormal.

Operating an ECG monitor requires professional knowledge and skills; it is recommended to perform the procedure under the guidance of qualified healthcare personnel.
