To have good health, human blood needs to have an oxygen saturation (SP02) of between 95 - 100%. If you have as low as 92%, it is a source of concern and you need extra oxygen at the hospital. Here at HLR-hjälpen, you will find pulse oximeters that help measure the oxygen saturation in your blood. In this way, you can quickly and easily check the health status of a person, regardless of whether they are conscious or not. A pulse oximeter is very easy to use. It is attached to the finger and then begins to measure both the blood's oxygen saturation and the pulse (bpm) in order to be able to quickly give an answer regarding the state of health.
A pulse oximeter: https://www.sciencedirect.com/science/article/abs/pii/S0735675799900190, is a medical measuring instrument. Everyone can have use for it and since it is a small device, it can easily be accommodated in a first aid bag. A pulse oximeter uses a non-invasive method, so it does not pierce the skin to be able to measure heart rate and oxygen saturation. Instead, you pinch the device to your fingertip to measure. The fact that the device is non-invasive also means that it is completely painless to use.
The pulse oximeter shines through the body part, usually the finger, with two different wavelengths of light. Partly a red light and partly an infrared light. Then there is a receiver that picks up the light signals. In this way, the oxygen saturation and heart rate can be measured. The pulse oximeter can namely read how much of the different lights have been absorbed at and between the pulse beats.
A pulse oximeter is good to use on patients suffering from various lung diseases such as COPD or chronic bronchitis. These people can advantageously store a pulse oximeter at home to measure their state of health themselves. By storing a pulse oximeter in workplaces and public places, many people can quickly get help. People with poor blood oxygenation can use a pulse oximeter several times a day to monitor their health.
However, it is not only in emergency care and monitoring of health conditions that a pulse oximeter can be used. It is also good to have at hand if you perform various high-altitude activities, such as rock climbing, hiking or high-altitude training. The device is easy to use and only needs a few seconds of measurement to show a result.
When using a pulse oximeter, it is important to be aware that nail polish and loose nails can affect the measured value and give an unreliable result. Surrounding light such as strong fluorescent lamps can do the same as the pulse oximeter can absorb this light. If a pulse oximeter is to be used on a neonatal patient, it needs a different device than an adult.
A pulse oximeter is a really good investment. It is used by emergency medical care, by elite athletes, by chronically ill people and should preferably be in first aid bags. It is a small device that does not require much space and it has a long lifetime. The only thing you need to replace on your portable heart rate monitor are the batteries that powers it. It is also good to clean it between uses so that it is kept hygienic.
