What are the parameters of the monitor?
The commonly seen monitors usually refer to bedside monitors, which are relatively common and are widely used in hospital intensive care units and coronary heart disease care units. It is set up at the bedside to connect with the patient to monitor certain states of the patient (such as heart rate, respiration rate, body temperature, blood pressure, etc.) and display the parameters. It often forms a system with the central monitor for monitoring. Other monitors are basically the same in terms of parameters, but may differ in appearance. This article focuses on introducing bedside monitors to readers.
The main parameters displayed in the ECG-ECG part are heart rate.
It is the number of times the heart beats per minute. The resting heart rate of normal adults has significant individual differences, with an average of about 75 beats/min (between 60 and 100 beats/min).
Heart rate can vary by age, gender, and other physiological conditions. The heart rate of newborns is very fast, reaching more than 130 beats per minute. In adults, women's heart rates are generally slightly faster than men's. In the same person, the heart rate slows down during rest or sleep, and increases during exercise or emotional agitation. Under the influence of certain drugs or neurohumoral factors, the heart rate will increase or decrease. People who do physical work and physical exercise regularly have a slower heart rate.
NIBP - non-invasive blood pressure (IBP - is invasive)
The dietary treatment of blood pressure patients is based on the principle of reducing sodium salt, reducing dietary fat, supplementing an appropriate amount of high-quality protein, paying attention to calcium and potassium supplementation, eating more vegetables and fruits, quitting smoking and drinking, and drinking water scientifically.
SpO2 - blood oxygen saturation
Blood oxygen saturation (normal value is 90-100, most people are 99-100, the more hypoxia, the lower)
The metabolic process of the human body is a biological oxidation process, and the oxygen needed in the metabolic process enters the human blood through the respiratory system, combines with hemoglobin (Hb) in the red blood cells, and combines into oxyhemoglobin (HbO2), which is then transported to various parts of the human body. some tissue cells.
Blood oxygen saturation (blood oxygen for short) is the percentage of the capacity of oxyhemoglobin (HbO2) bound by oxygen in the blood to the total capacity of hemoglobin (Hb) that can be bound by oxygen, that is, the concentration of blood oxygen in the blood, which is a function of respiration and circulation. important physiological parameters. The functional oxygen saturation is the ratio of HbO2 concentration to HbO2+Hb concentration, which is different from the percentage of oxyhemoglobin. Therefore, monitoring arterial oxygen saturation (SaO2) can provide an estimate of the oxygenation of the lungs and the oxygen-carrying capacity of hemoglobin. The oxygen saturation of normal human arterial blood is 98% and that of venous blood is 75%. Oxygen saturation is the percentage of the capacity of oxyhemoglobin (HbO2) bound by oxygen in the blood to the total capacity of bound hemoglobin (Hb), that is, the concentration of blood oxygen in the blood, which is an important physiological parameter of the respiratory cycle. SPO2= Hb oxygen content/Hb oxygen capacity×100%. It is an important indicator to reflect the oxygen supply status of the body. It is generally believed that the normal value of blood oxygen saturation should not be lower than 94%, and below 94% is regarded as insufficient oxygen supply. Some scholars regard blood oxygen saturation less than 90% as low. Oxygenemia criteria.
Significance of Monitoring Blood Oxygen Saturation Oxygen is indispensable in life activities. Oxygenated hemoglobin formed by the combination of oxygen in blood and reduced hemoglobin (Hb) is transported to whole body tissues. The traditional blood oxygen saturation measurement method is to collect blood from the human body, and then use a blood gas analyzer for electrochemical analysis to measure the partial pressure of oxygen and calculate the blood oxygen saturation. It can monitor the oxygenation function and detect hypoxemia early.
RR - respiratory rate
Respiration refers to the patient's breathing rate, or breathing rate. Respiratory rate is the number of times a patient breathes in a unit time. When breathing calmly, neonates are 60 to 70 breaths/min and adults are 12 to 18 breaths/min. In a quiet state, 16 to 20 times per minute, the breathing movement is even, and the ratio to the pulse rate is 1:4. Men and children mainly use abdominal breathing, and women mainly use thoracic breathing.
TEMP - body temperature
Body temperature, the normal value is less than 37.3 ℃, and if it is greater than 37.3 ℃, it means a fever. Some monitors do not have this.
Precautions
Each instrument has different settings, but the main parameters are these
This article only gives readers a general understanding of these parameters. If you want to know more about them, you can find relevant content for in-depth study.
