With the continuous development of modern medicine, monitors as the basic equipment of hospitals are being widely used in ICU, CCU, anesthesia, operating rooms and clinical departments of hospitals, which can provide important information of patients' vital signs to medical staff. Using this information, clinicians can better analyze the patient's condition, so as to take appropriate treatment measures and obtain the best results. Therefore, the role of monitors is getting more and more attention.
01. What is a monitor?
The monitor is an instrument used to monitor and evaluate the patient's physiological indicators in real time, and on this basis, data recording, trend judgment, event review, etc.; clinical monitors are mainly divided into transport monitors, bedside monitors, plug-in monitors instrumentation and telemetry monitors. The main function of the bedside monitor is to clinically monitor the main physiological indicators such as ECG, blood pressure, blood oxygen, body temperature, respiration, heart rate, ETCO2, etc., and send out prompts and alarm functions in combination with the normal range.
02. Where is the monitor used?
There are many application scenarios for monitors, and monitor products are needed both inside and outside the hospital. Scenarios where monitoring products will be used include: hospital: emergency department, outpatient clinic, general ward, intensive care unit, operating room, hospital transfer, etc. Outside the hospital: clinics, nursing homes, ambulances, households, etc.
03. When is guardianship required?
1. When the condition is critical and vital signs (blood oxygen, blood pressure, heart rate, respiration) need to be closely observed.
2. After various surgical operations, monitoring is required to observe whether there are any adverse reactions during the operation and whether the vital signs are stable.
3. When taking special medication, if the medication used has a great impact on blood pressure and heart rate, it is necessary to monitor and adjust the dosage of the medication.
4. Auxiliary and clear diagnosis: Real-time monitoring can obtain the information of the patient's attack, and assist in completing the diagnosis. For example, arrhythmia can be found during remote ECG monitoring, and the diagnosis can be confirmed.
04. How to read the value on the display?
Taking the Dawei monitor as an example, the ECG monitor generally has an electrocardiogram on the top, a column of values from top to bottom, HR stands for heart rate; SPO2 stands for blood oxygen saturation; RESP stands for respiratory rate; CO2 stands for carbon dioxide; TEMP stands for body temperature; NIBP is non-invasive blood pressure, which is usually called blood pressure. The numerical reference is as follows:
Heart rate: The average heart rate of a normal person is around 75 beats/min (between 60-100 beats/min).
Blood oxygen saturation: normal is generally between 90% and 100%, and <90% indicates that there may be hypoxemia.
Respiratory frequency: The normal range of breathing is 12-20 times/min, <12 times/min indicates slow breathing, >20 times/min indicates faster breathing.
Carbon dioxide: Monitoring of end-tidal CO2 concentration or partial pressure (ETCO2) can reflect pulmonary ventilation and can also reflect pulmonary blood flow. ETCO2 can reflect PACO2 (arterial blood carbon dioxide), and 5% of normal ETCO2 is equivalent to 5KPA (38MMHG).
Body temperature: In general, it is measured once in one to two hours after operation, and the normal value of body temperature is less than 37.3°C. After the operation, due to lack of water, it may be slightly higher. With the infusion, the body temperature will tend to be normal.
Blood pressure: Generally, blood pressure will be measured one to two hours after surgery. The left and right values represent systolic blood pressure and diastolic blood pressure respectively. The normal range of systolic blood pressure is 90-140MMHG, and the normal range of diastolic blood pressure is 60-90MMHG.
05. When can I stop using it?
Using the ECG monitor will restrict the patient's activities and bring some discomfort. Therefore, when the condition improves slightly, I want to take off the ECG monitor in a hurry. When can I take off the ECG monitor?
The improvement of the disease that you see is only the improvement of symptoms or superficial improvement. Doctors will evaluate the improvement of the disease based on the natural course of the disease, the severity of the original disease, and the results of laboratory tests. Only when the condition is stable can it be Disable the monitor.
