The Maintain of Patient Monitor

The monitor is a device or system that measures patient physiological parameters. The doctor will set the standard value on the device. When the value is higher than it, the device will send an alarm to the terminate end. It can continuously observe the physiological parameters of the patient in real-time and detect the trend of change. It is a reliance to deal with the emergency, minimize complications, and achieve the purpose of alleviating and eliminating the condition. In addition to measuring and monitoring physiological parameters, it also includes monitoring and processing before and after medication and surgery.

What can we monitor with the devices?
The basic parameters of the monitor consist of electrocardiogram (ECG), respiration (RESP), non-invasive blood pressure (NIBP), blood oxygen saturation (SpO2), pulse, body temperature (TEMP). In addition, optional parameters include invasive blood pressure (IBP), end-breathing carbon dioxide (EtCO2), anesthetic gas (AG), cardiac output (CO), etc.

The scope of clinical application of the monitor includes during surgery, after surgery, trauma care, coronary heart disease, critically ill patients, newborns, premature babies, hyperbaric oxygen chambers, delivery rooms, etc.
According to the monitor structure, they contain four categories, portable monitors, plug-in monitors, telemetry monitors, and HOLTER (24-hour dynamic electrocardiogram) ECG monitors.

Monitors have three categories according to their functions: bedside monitors, central monitors, and outpatient monitors (telemetry monitors)


Daily maintenance of ECG monitor

1. The monitor should be protected from sunlight to avoid abnormal temperature rise in the machine.
2. The instrument should be placed in a fixed position to prevent vibration.
3. After use, clean and disinfect the fuselage wires and accessories.
4. Regularly check whether the monitor feature is correct, and solve the problem in time.
5. If the plug-in, the lead wire is well prepared. And keep it in a fixed position and a standby state.
6. ​​Do not adjust these various components to cause undue malfunctions and affect the use.

7. If the monitor is set alone for a long time, it should be placed in a dry place and covered with a dust cover.
8. The monitor screen is wiped with 95% alcohol once a week
9. Timely registration, inspection, and repair

ECG monitor operation process

1. Check whether each socket is loose, turn on the power, turn on the monitor switch, check the monitor performance, select the ECG lead wire, select the monitoring mode, and check whether the instrument is working properly.

2. Skin preparation (70% alcohol wipes the skin)
3. Connect the electrode, paste the electrode sheet, and fix it correctly.

LA——The lower edge of the left mid-

line of the clavicle is close to the left shoulder.
RL——Right quarter rib
LL—— Left quarter ribs
VV——On the chest wall

L (left arm) electrode-under the clavicle, near the left shoulder
F (left leg) electrode-left lower abdomen

4. Connect blood pressure cuff

 Choose the right cuff size.

 Do not install cuffs on limbs with intravenous fluids or intubation.

 5. Connect the spo2 sensor and clamp the blood oxygen probe to the finger or toe.
6. ​​The temperature probe is clamped under the patient's armpit
7. Adjust alarm parameters: heart rate, blood pressure, pulse, respiration, blood oxygen.
 6. ​​Detect and record the patient.
