Pulse Oximeters: Safest Way to Know About Oxygen in the Body

Pulse Oximeters are essential tools which help to measure the level of oxygen and the pulse rate of a human being with right accuracy. Pulse oximetry is a test which is painless and can make the best measurement. It is one of the ways through which you can measure how oxygen is being circulated in different parts of the body. Pulse oximetry meter is a device which you can place at any body part and it utilizes the light to ascertain how much oxygen is present in the blood. This measurement makes it easier for the physician to decide on whether the person is in need of extra oxygen or not.

Presently there are many kinds of digital pulse oximeters which are available in the market. However, choosing the right kind of oximeters becomes difficult.

Why Do You Need Pulse Oximetry?
Pulse oximetry is utilized to measure the oxygen concentration in the blood. There are several prospects for which you might need a pulse oximeter. Either during or after surgical operations or any kind of procedures which requires sedation, you can use pulse oximetry to check how far the lungs medicines are working and a person’s capacity to manage high voltage activity levels. Furthermore, you can also take the help of pulse oximeter to check if ventilation is necessary for breathing and you can measure sleep apnea too.

How does a Pulse Oximeter work? 
The device comprises of a small clamp which is placed on a finger, toe or earlobe. The reading is recorded as rays of light pass through the blood and measures the concentration of oxygen. The entire procedure is encapsulated by assessing the light absorption on the portions where oxygen is present and to the portions where there is no oxygen. Surprisingly, the process is not at all painful. Along with chechking the oxygen, it also takes in account the heart rate of a person.

Pulse Oximetry Readings 
Pulse oximetry is a reasonably reliable analysis. This is particularly valid when physicians use high-grade equipment. For instance, if the device is showing 90% as readings that means your actual oxygen level is 90% to 95%. But there is a catch as the waveform quality and the individual's assessment is a crucial factor.  Additional factors like movement or temperature can disrupt the reading and you might not get the right record.

The standard reading of oxygen in human blood must be 95%. This is the real saturation level which is required to have a healthy body. If your body is showing a rate below the above-mentioned reading score then it is not a matter of concern. But, if the readings are consistently low then it will compel you to go for a checkup. If you have 92% oxygen, it suggests that you have hypoxemia which is known as the situation where your body has low oxygen. 

Pulse oximeters are an easy, non-invasive, and absolutely painless experiment. It appears that the use of pulse oximeter involves no risk neither has any effect on the skin. There are specific kinds of adhesive penetrated in probes which further does not create any sort of skin inflammation.
