[Pulse oximeter]The role of pulse oximeter How to use pulse oximeter
Pulse oximeter The role of the saturation meter
The pulse oximeter integrates the design technology of today’s miniature precision instruments. The oxygen saturation meter is suitable for business people flying on business trips. It is used when traveling. It is convenient for middle-aged and elderly people and children to self-test, safe and secure. Save time and worry. Using intelligent technology, the pulse oximeter has successfully completed a new operation mode of “one finger detection, one machine and two uses”. scope.
The function of pulse oximeter is as follows: it is suitable for monitoring blood oxygen in the process of first aid and transportation, fire rescue, high-altitude flight; heart disease, hypertension, diabetes, especially the elderly will If you have breathing problems, monitoring blood oxygen indicators can be a good way to know whether your breathing and immune system are normal. Blood oxygen saturation has become an important physiological indicator for daily monitoring in ordinary families. Oxygen, as a must-monitoring item, tends to overwhelm the stethoscope; patients with respiratory diseases, especially those with long-term snoring and those who use ventilators and oxygen concentrators, use oximeters in daily life to monitor treatment effects; outdoor exercisers , Mountaineering enthusiasts, and sports players use oximeters when exercising to know their physical conditions in time and take necessary protective measures.
How to use a pulse oximeter
The pulse oximeter works well and is suitable for people with heart disease, high blood pressure, diabetes, Especially the elderly will have breathing problems. Monitoring blood oxygen indicators can provide a good understanding of whether their breathing and immune systems are normal. Blood oxygen saturation has become an important physiological indicator for daily monitoring in ordinary families. It also takes blood oxygen as a necessary monitoring item, and the number of use tends to exceed the stethoscope; patients with respiratory diseases, especially those who snore for a long time and use ventilators and oxygen concentrators, use blood oximeters in daily life to monitor the effect of treatment .
The usage of the pulse oximeter is very simple:
1. Insert two AAA batteries according to the positive and negative marks in the battery compartment and cover the batteries cover.
2. Pinch open the clip.
3. Insert your finger into the rubber hole (the finger should be fully inserted) and release the clip.
3.1. Press the button on the front panel.
3.2. It is best not to shake the finger under test during use, and it is best not to move the human body.
4. Read the relevant data directly from the display screen.
5. In the working state, lightly press the button to change the display direction.
6. In the working state, long press the button to change the screen brightness.
Notes on using the pulse oximeter
If the measured part of the patient’s limb moves vigorously during the measurement, it will affect this condition. The extraction of a regular pulse signal makes the measurement impossible. When the patient’s peripheral circulation is seriously poor, such as a shock patient, the arterial blood flow at the measured site will be reduced, making the measurement inaccurate or impossible. When strong light shines on the blood oxygen probe from the outside, it may cause the photoelectric receiving device to deviate from the normal range, resulting in inaccurate measurement. Therefore, the blood oxygen probe should try to avoid strong light exposure. Oxygen saturation measurement can be difficult when nail polish is applied to the nails or blood pressure is measured on the same arm.
Factors affecting blood oxygen saturation monitoring: the sensor position is not in place; nails are too long, and nail polish affects signal detection; strong light environment interferes with the signal; shock patients, the skin temperature is too low; When blood pressure is measured in the ipsilateral arm, peripheral vascular pulsation is affected, making measurement difficult.
normal value of blood oxygen saturation
blood oxygen probe type: adult type, children’s multi-function type. In the plain area, the blood oxygen saturation of normal people is above 94%, and below 94% is insufficient oxygen supply. Some scholars set SpO2<90% as the standard for hypoxemia. Therefore, the SpO2 alarm lower limit of the pulse oximeter is generally set to 90%.
