We all know that heart pumps blood throughout the body which carries oxygen to protect our lives. To measure the correct oxygen level, a pulse oximeter is used in hospitals for mainly chronic patients. Patients with diseases like asthma, pneumonia, heart attack, chronic obstructive pulmonary disease, cancer, anemia, and congenital heart defects are checked with the oximeter.

How It Works

When the small clamp-like device is placed on the earlobe, toe, or on the right finger of the patient’s body, small beams of light start to pass through the blood to measure the oxygen level of the body along with the pulse rate. This painless process helps to detect the changes in oxygenated and deoxygenated blood.

The oximeter starts to send small beams of light through your finger and monitor the pulse and oxygen saturation. During the physical activities, surgery, and recovery period, the meter will be placed beforehand and once your monitoring is over or you are awake it can be removed.

Pulse Oximeter Readings

When doctors set pulse oximeter in the finger of the patient, it is vital to have accurate readings. Using high-quality devices in the hospital or nursing home is important. It is true that there is a difference of 2% in the result you can find. For example, if the reading shows 92% it can be anywhere about 90% to 94%. However, you can consider the waveform of the pulse oximeter to each individual. All through temperature, nail polish, and movement. Check out LED and OLED Fingertip Pulse Oximeter. It is comfortable and easy to use. Besides, the material is of pure silicone gel for accurate reading. Thus it provides comfort on your fingertips.

To keep your body and cells healthy, you need to have a minimum of 82% reading, which means that your blood should carry 82% oxygen to the whole body. Below this level of oxygen saturation does not mean that it can cause damage to your body.


Before purchasing the oximeter you have to know the accuracy of the device and know that it can work properly on a variety of patients.
