Function of pulse oximeter
Pulse oximeter integrates the design technology of today's miniature precision instruments, which is only the size of a lighter and pocket-sized, occupying almost no space. The pulse oximeter is suitable for business people to travel by plane. Convenient for middle-aged and elderly people and children to test themselves, safe and secure, saving time and worry. Using intelligent technology, the pulse oximeter successfully completed a brand-new operation mode of "one finger detection, one machine for two purposes". Pulse oximeter is used in hospitals, families, oxygen bars, community medical care, plateau areas and sports health care.
The functions of pulse oximeter are as follows: it is suitable for patients to monitor blood oxygen during emergency transport, fire fighting and high-altitude flight; People with heart disease, hypertension and diabetes, especially the elderly, will have respiratory problems. Monitoring blood oxygen index can know whether your breathing and immune system are normal, and blood oxygen saturation has become an important physiological index for daily monitoring in ordinary families. Medical staff also regard blood oxygen as a necessary monitoring item in ward rounds and home visits, and the frequency of use tends to overwhelm stethoscope; Patients with respiratory diseases, especially those who snore for a long time and use ventilators and oxygen generators, use oximeters to monitor the therapeutic effect in their daily lives; Outdoor athletes, mountaineers and sportsmen all use oximeters during exercise to know their physical condition in time and take necessary protective measures.
Use of pulse oximeter
Pulse oximeter is very effective, suitable for people with heart disease, hypertension and diabetes, especially the elderly, who will have breathing problems. Monitoring the blood oxygen index can well know whether their respiratory and immune systems are normal, and blood oxygen saturation has become an important physiological index for daily monitoring in ordinary families. Medical staff also regard blood oxygen as a necessary monitoring item in ward rounds and home visits, and the frequency of use tends to overwhelm stethoscope; Patients with respiratory diseases, especially those who snore for a long time and use ventilators and oxygen generators, use oximeters to monitor the therapeutic effect in their daily lives.
The use of pulse oximeter is simple:
1. Put two No.7 (AAA) batteries into the battery compartment according to the sign and cover them.
2. Open the clip.
3. Insert your finger into the rubber hole (it is best to extend your finger completely), and then loosen the clip.
3. 1. Just press the button on the front panel.
3.2. It is best not to shake the measured finger during use, and the human body should not be in motion.
4. Read relevant data directly from the display screen.
5. In the working state, press this key lightly to change the display direction.
6. In the working state, long press this key can change the brightness of the screen.
Matters needing attention in using pulse oximeter
If the measured part of the patient's limb moves violently during the measurement, it will affect the extraction of this regular pulse signal, thus making the measurement impossible. When the patient's peripheral circulation is seriously blocked, such as shock patients, it will lead to the decrease of arterial blood flow in the measured part, making the measurement inaccurate or impossible. When the external strong light shines on the blood oxygen probe, the photoelectric receiver may deviate from the normal range, resulting in inaccurate measurement, so the blood oxygen probe should try to avoid the strong light. It is difficult to measure oxygen saturation when painting nail polish or measuring blood pressure with ipsilateral arm.
The factors affecting the monitoring of oxygen saturation: the sensor position is not in place; Nail polish affects signal detection because the nail is too long; Interference of strong light environment on signals; Shock patients, skin temperature is too low; When measuring the blood pressure of ipsilateral arm, it affects the pulsation of peripheral blood vessels, which makes it difficult to measure.
