PULSE OXIMETER READING SKIN
Many other brands of finger pulse oximeters are unable to perform with accuracy on patients with low perfusion or dark skin pigmentation, and can’t stand up to repeated daily use. However, not all pulse oximeters deliver the same level of performance and versatility. All you have to do is place it on any finger and wait a few seconds for it to measure your current SpO 2 and heart rate. Arterial blood gas measurements, obtained by arterial puncture, remain the gold standard for measurement of oxygen saturation.Ī personal finger pulse oximeter is designed to be fast, durable and intuitive. Pulse oximetry can be a useful aid in decision-making, but is not a substitute for a clinical assessment, nor sufficient for diagnosis by itself. Under the guidance of their physicians, people with heart and breathing problems can use personal finger pulse oximeters to manage their conditions and assess the efficacy of treatment methods. These compact, noninvasive devices attach painlessly to the fingertip and send wavelengths of light through the finger to assess SpO 2 and pulse rate. Today’s medical experts have access to a wide variety of SpO 2 monitoring tools, including finger pulse oximeters. Â- In a patient with stable chronic disease (e.g., COPD), an SpO 2 of 92% or less should prompt referral for further investigation of the need for long-term oxygen therapy. Â- In a patient with acute respiratory illness (e.g., influenza) or breathing difficulty (e.g, an asthma attack), an SpO 2 of 92% or less may indicate a need for oxygen supplementation. That being said, here are a few general guidelines on SpO 2 for individuals with acute respiratory issues and chronic diseases: These individuals should always consult with their doctor for information on acceptable oxygen levels for their unique state of health. This condition is often referred to as hypoxemia, and its symptoms include severe shortness of breath, increased heart rate and chest pain.įor people with chronic lung conditions and other breathing problems, the “normal†SpO 2 range of 95% to 100% doesn’t apply. Values under 90 percent are considered low, and indicate the need for supplemental oxygen. Your “Normal†SpO 2 RangeĪccording to the Mayo Clinic, normal pulse oximeter readings usually range from 95 to 100 percent. People afflicted by these health problems often have a lower SpO 2 average, necessitating the use of supplemental oxygen and other treatment methods. There are several adverse conditions and diseases that can negatively impact SpO 2, including asthma and chronic obstructive pulmonary disease (COPD). However, as long as your SpO 2 stays within a healthy range amidst these fluctuations, there’s no need for concern.Ĭhanges in activity aren’t the only factors that impact oxygen saturation. It’s possible (and perfectly natural) for your SpO 2 to change throughout the day, particularly if you’re transitioning from low-energy to high-energy activities. Now, this is where things get more complicated.
So if your red blood cells contain 95% oxygenated and 5% non-oxygenated hemoglobin, your SpO 2 would be 95%.
Pulse oximetry devices represent this measurement using a simple percentage. In other words, it’s an estimation of how much oxygen the hemoglobin in your blood contains compared to how much it could contain.

Oxygen saturation (SpO 2) measures how much oxygen blood carries in comparison to its full capacity.
