1, too low ND means too low diastolic pressure, and too low ns means too low systolic pressure.
2. In ECG monitor, ND stands for low voltage and NS stands for high voltage.
3. ECG monitor is a practical precision medical instrument in the hospital, which can monitor the patient's dynamic and practical precision medical instrument at the same time.
4. ECG monitor can monitor ECG, respiration, body temperature, blood pressure (non-invasive and invasive), oxygen saturation, pulse rate and other physiological parameters.
It takes a certain pressure for human blood to be transported to all parts of the body. This pressure is blood pressure. The lateral pressure of blood in blood vessel on the unit area of blood vessel wall, that is, pressure. Because blood vessels are divided into arteries, capillaries and veins, there are arterial blood pressure, capillary blood pressure and venous blood pressure. Usually, blood pressure refers to arterial blood pressure. When blood vessels dilate, blood pressure drops; Blood pressure rises when blood vessels contract.
6. systemic arterial blood pressure is called blood pressure. Blood pressure is the pressure acting on the blood vessel wall when blood flows in blood vessels, and it is the driving force to promote blood flow in blood vessels. Ventricular contraction, when blood flows from the ventricle into the artery, the pressure of blood on the artery is the highest, which is called systolic blood pressure. Ventricular diastolic, arterial blood vessels elastically retract, blood continues to flow slowly forward, but blood pressure drops, and the pressure at this time is called diastolic pressure.

The important role of the monitor:
Monitors are different from monitoring diagnostic instruments. It must continuously monitor the physiological parameters of patients for 24 hours, detect the changing trend, point out the critical situation, and provide the basis for first aid and treatment for doctors, so as to minimize complications and achieve the purpose of relieving and eliminating diseases.
The purpose of the monitor is not only to measure and monitor physiological parameters, but also to monitor and handle the situation before and after medication and operation.
The standard six parameters of the monitor are ECG, respiration, noninvasive blood pressure, oxygen saturation, pulse and body temperature. In addition, optional parameters include: invasive blood pressure, end-expiratory carbon dioxide, respiratory mechanics, anesthetic gas, cardiac output (invasive and noninvasive), bispectral index, etc.
Clinical application scope of the monitor:
Intraoperative and postoperative care, trauma care, coronary heart disease, critically ill patients, newborns, premature infants, hyperbaric oxygen chambers, delivery rooms, etc.
