The multi-parameter monitor can provide important patient information for medical clinical diagnostic monitoring. It detects the human body’s ECG signal, heart rate, blood oxygen saturation, blood pressure, respiratory rate, body temperature and other parameters in real time, which is an essential device for monitoring the vital signs of patients.

For medical staff, various abnormal alarms often appear during the use of the patient monitor, which requires clinical users to quickly grasp the constantly updated knowledge of the operation and management of the monitor. This article shares the knowledge of the use and management of the patient monitor in practice.

Different kinds of monitors

01 Classification of patient monitors

Monitors are classified according to the usage scenarios, and can be divided into bedside monitor, central monitoring system, special neonatal monitor, etc., among which the more common is the bedside monitor that is usually set at the bedside and connected to the patient. It can monitor the heart. Various physiological parameters such as electricity, blood pressure, respiration, body temperature and heart rate.

02 Common monitor usage problems

Why is it recommended to wear blood oxygen finger cuff for the monitor?

Wearing a blood oxygen saturation finger cuff is much faster than connecting an ECG lead, by which the patient’s pulse rate and blood oxygen saturation can be monitored in a short time, and medical staff can quickly complete the assessment of the patient’s basic physical signs.

Can the blood oxygen finger cuff and the blood pressure monitor cuff be on the same side?

When measuring blood pressure, it will block and affect arterial blood flow, which may lead to inaccurate blood oxygen saturation during the measurement. Therefore, it is usually not recommended that the blood oxygen saturation finger cuff and the automatic blood pressure monitor cuff be on the same side of the limb in clinical practice.

Is it necessary to replace the electrode pad when continuously monitoring the patient?

Yes, it needs to be replaced. Since the electrode pads are stuck on the same part for too long that will cause skin rashes and blisters, so the skin condition should be checked frequently. Even if the skin is intact, the electrode pads and the sticking site should be replaced once every 3 to 4 days to avoid causing skin breakage to the patients.

In addition, the electrode pads on the patient should also be removed in time after ECG monitoring.

03 What exactly are the 3 Key Points of operating the monitor?

  1. Check
    Confirm the pasting status of the electrode pads, check the quality and location of the heart electrode pads, and check whether there is any problem with the lead wires on the basis that the electrode pads are pasted and there is no problem with the quality.
  2. Exclude
    Check the external part of the ECG lead (the three/five extension cords in contact with the human body should be connected to the corresponding three/five contact pins on the ECG plug).
  3. Attention
    Pay attention to the connection steps
    The electrode pad connection steps should be correct like cleaning and connection sequence of the skin surface, and operate in accordance with the regulations.
    Pay attention to the patients and their family members
    Nursing staff and patients’ family members should not pull the electrode wires and lead wires. Patients and relatives should be informed that they can not use or adjust the monitor without authorization, causing damage to the devices.
    Pay attention to the maintenance when using the monitor for a long time
    The electrode pads are easy to fall off in long-term application, which affects the accuracy and monitoring quality. Therefore, skin cleaning, disinfection and electrode replacement are needed.
