In order for your body to work optimally, the oxygen saturation of the blood should be between 94 and 99 percent. However, in the case of a severe respiratory infection, vicks rapid read thermometer the actual oxygen saturation can sometimes fall drastically below this ideal value. To help you recognize more quickly when it becomes dangerous, a pulse oximeter is recommended.
Our comparison table provides you with an overview of numerous pulse oximeters. Prepare for your pulse oximeter test by reading important purchase criteria such as the possibility of long-term measurement, app control as well as the question of the type of battery. A practical brand overview also awaits you in the further course.

The most important in a nutshell
- Pulse oximeters are medical measuring devices. They can be used not only to determine the oxygen saturation of the blood but also to measure the pulse.
- Pulse oximeters are used in hospitals, for example, in the intensive care unit. They are also used for operations that require anesthesia of the patient.
- Pulse oximeters can also be suitable for domestic use. This is always useful if a member of one’s own household is affected by chronic disease of the respiratory tract, which makes an oxygen saturation measurement necessary in an emergency.
Do you want to know how bad you or your child really are with acute bronchitis or another respiratory disease? Would you like to monitor your pulse and oxygen saturation at home yourself and thus detect emergencies more quickly in order to act in time?
Then it is best to get a handy pulse oximeter. In 2022, this guide will tell you which factors you should consider in your pulse oximeter test. Not only can you read about how a pulse oximeter works, but you can determine your test winner in no time at all based on factors such as the possibility of app networking, size, color, and design.
What does the oxygen saturation of the blood say?
Oxygen saturation provides information about what proportion of the hemoglobin present in the blood contains oxygen. With the help of oxygen saturation, statements can be made about the state of breathing. If a child or adult has severe bronchitis or pneumonia, it is possible to decide on the basis of this value whether the administration of additional oxygen is indicated.
What do I measure with a pulse oximeter?
A pulse oximeter, just like a insertion of thermometer or a blood pressure monitor, is a medical measuring device that is not only suitable for determining the pulse. Likewise, you can use a pulse oximeter to learn about oxygen saturation in the blood. Pulse oximetry is a non-invasive method for measuring blood oxygen, which is why the measuring device required for this is called a pulse oximeter. The meter works as follows:
Clip the pulse oximeter clip to your finger, earlobe, or toes.
Turn on the pulse oximeter and carry out the measurement non-invasively, i.e. without the need for a blood sample.
The light source sends infrared light waves through the finger.
On the opposite side of the clip, there is a sensor that measures the incoming light waves.
Depending on the oxygen saturation, the blood swallows different amounts of light.
Accordingly, the oxygen saturation, which the pulse oximeter displays on the display, can be measured on the basis of the incoming light waves.
