Holiday Travel Health Strategy

With the weather gradually warming up, many people are planning to go out to play. But when you go out, don't forget to pay attention to your health, after all, spring is the season of various diseases, the human body is more prone to ischemia and hypoxia. It is a good idea to bring a small and convenient oximeter in your suitcase, which can monitor your body condition anytime and anywhere, so that the whole family can travel healthily.
In spring, sympathetic excitability is higher than in winter, which leads to higher blood pressure, faster heart rate, higher concentration of adrenocorticotropic hormone and norepinephrine in the blood, faster metabolism, increased platelet activity and higher blood viscosity, which increases the burden on the cardiovascular system and oxygen consumption, leading to ischemia and hypoxia.
Especially for people suffering from cardiovascular diseases, respiratory diseases, elderly people and people who travel to the plateau, the oximeter can quickly detect the oxygen saturation and pulse rate, which can prompt people to replenish oxygen for the body and prevent the adverse consequences caused by hypoxia.
Although many people bought the oximeter home, but is not clear on the instrument screen those complex readings are what means ...... do not worry, here has been summed up for you a good ultra-detailed oximeter use strategy, quickly forward your family and friends to learn it together ~
Saturation of blood oxygen (SPO2):
The abbreviation for blood oxygen saturation is SPO2, where S is for saturation, P is for pulse, and O2 is for oxygen. Blood oxygen saturation refers to the concentration of blood oxygen in the blood, and also the amount of oxygen carried by red blood cells. It is not only an important physiological parameter for respiratory and circulatory functions, reflecting whether the body is hypoxic or not, but also an important indicator for the normal functioning of the body.
What is the normal blood oxygen saturation level?
Normal health 94%-100%
Mild hypoxia 90%-94%
Severe hypoxia <90%
Pulse Rate (PRbmp):
The pulse rate is the frequency of arterial beats. In normal people, the pulse rate and heartbeat are the same; in adults, more than 100 beats per minute is called tachycardia, and less than 60 beats per minute is called bradycardia. There are many clinical conditions, such as fever, that can also increase the heart rate, especially heart disease, which can cause changes in pulse rate. Therefore, measuring the pulse rate is an indispensable test for patients.
Perfusion index (PI):
The perfusion index PI value reflects the pulsatile blood flow, i.e., the perfusion capacity of the blood flow. Usually PI is used as a parametric index that reflects the perfusion status of the tested limb and indicates the detection accuracy of the machine, i.e., it can still detect in conditions of low and weak perfusion.
If the PI value decreases significantly, it indicates the possible existence of hypotensive shock, insufficient blood volume in the body, etc., and is accompanied by sweating, weakness, chest tightness and other symptoms, and should promptly improve the electrocardiogram, cardiac ultrasound and other related examinations to clarify the presence of heart disease.
The normal range of perfusion index PI in the calm state is about 4-5, if the value drops significantly, you need to be alert to the presence of hypotension, and should promptly consult a doctor, under the guidance of the doctor to carry out the corresponding treatment.
The correct measurement method of oximetry
1. In a quiet state, the patient lies still in the hospital bed with hands on both sides of the body.
2. avoid monitoring oxygen saturation in the ipsilateral limb while blood pressure is being measured;
3. continuous monitoring of oxygen saturation for a long time should be done by changing the site once in 2h;
4. adjust the position of the finger and finger cover so that the red light is facing the nail bed and the finger measured during monitoring is flush with the heart;
5. After the data is smooth, record the readings accurately.
