In the early days, the purpose of multi parameter monitor was to detect the ECG signal, so at that time, multi parameter patient monitor was also called “ECG monitor”.

However, with the development of science and technology and the increasing clinical demand for detection parameters, the multi parameter monitor gradually introduced other parameters, such as blood pressure, body temperature and respiratory rate mentioned above.

Clinically, these data and indicators are combined with electrocardiogram (ECG), which can be used in ECG monitoring to understand the patient’s condition more comprehensively and provide sufficient auxiliary role for medical clinical diagnosis.

Is the multi parameter monitor and the ECG monitor the same thing?

To some extent, there is no problem for multi-parameter monitor to be called ECG monitor, that is to say, in a broad sense, multi-parameter monitor is ECG monitor.

As a very important project in the medical clinical diagnosis department, the multi-parameter monitor can realize the supervision and alarm of various parameters of the body, including the human ECG signal, heart rate, oxygen saturation, blood pressure, respiratory rate and body temperature, each parameter has a very important significance.

How to use multi parameter monitor?

1, the monitor is generally through the two electrodes of the ECG lead, with a sinusoidal constant flow of 10 ~ 100kHz carrier frequency into the body of 0.5 ~ 5mA current, so as to pick up the signal of respiratory impedance change on the same electrode. This map of the variation of respiratory impedance describes the dynamic waveform of respiration and can extract the parameters of respiratory rate.

2. As the fluid has the function of pressure transfer, the intravascular pressure will be transferred to the external pressure sensor through the fluid in the catheter. Thus, a dynamic waveform of the changes in the blood vessel pressure can be obtained, and the systolic, diastolic and mean blood pressure can be obtained by a specific calculation method.

3. During the measurement, the operator can place the body temperature probe on any part of the patient’s body as required. Since different parts of the body have different temperatures, the temperature measured by the monitor is the temperature of the part on the patient’s body where the probe is to be placed, which may be different from the temperature of the mouth or armpit.

4. Electrocardiogram (ECG) is to record the potential difference of the body surface in real time. The concept of lead refers to the waveform diagram of the potential difference between two or more parts of the body surface changing according to the cycle of movement.

5. Human arterial blood pressure is a variable physiological parameter. It has a lot to do with a person’s mental state, emotional state, as well as the posture and posture during measurement. Heart rate increases, diastolic blood pressure increases, heart rate slows, and diastolic blood pressure decreases. Systolic blood pressure must rise as stroke volume increases. It can be said that the arterial blood pressure is not the same during each cardiac cycle.

Clinically, the detection of some data is relevant, and doctors also need to know more data about patients, in order to confirm the physical condition of patients, in order to really do the “right medicine”.
