SpO2 Oximeter and Blood Oxygen: Things You Must Know

portable pulse oximeter device

When covid 19 pandemic hit the world in 2020 that is when most people got introduced to the oximeter device for the first time. Well, Oximeter is an innovative vital monitoring device to measure blood oxygen levels. As you know- Oxygen is essential for life and plays a crucial role in our body’s functioning, the cells need oxygen to produce energy, carry out cellular respiration, and conduct basic physical activities. Hence keeping a check on the oxygen levels is equally important. The SpO2 device has been around for some time but was not as widely available until now.

Let’s explore everything about SpO2 Oximeter, Oxygen Saturation, Normal Levels and more.

What is the SpO2 Level?

SpO2 stands for peripheral capillary oxygen saturation. It is a measure of the oxygen saturation of the blood or simply, a measure of the amount of oxygen in the blood. It is measured by a sensor of a non-invasive device that can be easily attached to the finger of patients. An oxygen saturation level of 95% to 100% is considered normal on a pulse oximeter. Keeping track of SpO2 levels is important for people who have had lung disease, cardiac problems, stroke or other neurological problems. They can also be used as an indicator of how well someone is doing after undergoing surgery or experiencing some type of trauma.

How is oxygen circulated in the body?

A person’s blood oxygen level measures how much oxygen is circulating in their body. Haemoglobin, a protein within red blood cells, carries oxygen, collecting it from the lungs and delivering it to the tissues and cells in your body.

Causes of Low Blood Oxygen


Hypoxia is a condition in which the oxygen level in the body falls below normal. It affects oxygen intake and lowers the amount of oxygen in bodily tissues.


  • Ineffective oxygen transport
  • Lung diseases and asthma attacks
  • Low concentration of oxygen in the air
  • Poisoning by cyanide or carbon monoxide


  • Shortness of breath
  • Coughing and wheezing
  • Increase in heart rate
  • Skin discolouration
  • Headache
  • Confusion and difficulty speaking
  • Fainting and temporary memory loss


Hypoxemia is a condition in which the body suffers oxygen deficiency or low oxygen content in the blood. It happens when there is not enough oxygen to support all of the body’s cells.


  • High altitude
  • Lung diseases or trauma
  • Heart diseases
  • Asthma attacks
  • Anaemia


  • Shortness of breath
  • Coughing and wheezing
  • Increase in heart rate
  • Headache and confusion
  • Skin discolouration

How does SpO2 Pulse Oximeter measure oxygen level?

The Oximeter like CuroOxy is a portable pulse oximeter device that can be used by patients and healthcare providers to monitor a patient’s oxygen levels. The SpO2 Pulsemeter works by measuring the light absorbed by your blood. It indicates the levels of oxygen in your blood. The device shines red light and infrared light through the patient’s fingertip. If the blood oxygen levels are good, it absorbs more infrared light and reflects more red light. On the other hand, the low oxygen levels absorb more red light and reflect infrared light.
