Blood Oxygen Saturation (SpO2)
Your SpO2 reading is an estimation of the amount of oxygen in your blood. An SpO2 reading of 95% or greater is generally considered to be a normal oxygen level. However, an SpO2reading of 92% or less (at sea level) suggests that your blood is poorly saturated. Insufficient saturation can cause a range of adverse health conditions—including chest pain, shortness of breath and increased heart rate.
Your pulse rate is an estimation of the number of times your heart contracts per minute. According to the Mayo Clinic, normal pulse rate values for adults range from 60 to 100 beats per minute (bpm). In general, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness. For some people, a pulse rate below 60 bpm indicates abnormally slow heart action, also known as bradycardia. Bradycardia can cause a number of problematic symptoms—including fainting, fatigue, chest pains and memory problems.
A pulse oximeter gives you accurate insights on your SpO2 and pulse rate within a matter of seconds, empowering you to respond quickly and confidently to abnormal readings. As a result, many people with adverse heart and breathing conditions invest in personal oximeters for in-home use.
Note: SpO2 and pulse rate measurements outside the normal range aren’t always a sign of health problems. For example, your heart rate can be expected to increase during exercise, and oxygen saturation may decrease slightly (it should still remain at 90% or greater).
For people with COPD, asthma or other lung diseases who want to stay active, the quality of their pulse oximeter is incredibly important. Fast, reliable oximeter readings play an essential role in helping patients adjust their oxygen flow when exercising, participating in social activities or spending time at home. High-quality monitoring devices can also help physicians with monitoring the efficacy of treatment efforts and respond quickly if the condition worsens. That’s why people spanning the globe count on a finger pulse oximeters for personal use.

Understanding Oxygen Saturation
Oxygen saturation (SpO2) measures how much oxygen blood carries in comparison to its full capacity. In other words, it’s an estimation of how much oxygen the hemoglobin in your blood contains compared to how much it could contain. Pulse oximetry devices represent this measurement using a simple percentage. So if your red blood cells contain 95% oxygenated and 5% non-oxygenated hemoglobin, your SpO2 would be 95%. Simple, right?
Now, this is where things get more complicated. It’s possible (and perfectly natural) for your SpO2 to change throughout the day, particularly if you’re transitioning from low-energy to high-energy activities. However, as long as your SpO2 stays within a healthy range amidst these fluctuations, there’s no need for concern.
Changes in activity aren’t the only factors that impact oxygen saturation. There are several adverse conditions and diseases that can negatively impact SpO2, including asthma and chronic obstructive pulmonary disease (COPD). People afflicted by these health problems often have a lower SpO2 average, necessitating the use of supplemental oxygen and other treatment methods.
Your “Normal” SpO2 Range
According to the Mayo Clinic, normal pulse oximeter readings usually range from 95 to 100 percent. Values under 90 percent are considered low, and indicate the need for supplemental oxygen. This condition is often referred to as hypoxemia, and its symptoms include severe shortness of breath, increased heart rate and chest pain.
For people with chronic lung conditions and other breathing problems, the “normal” SpO2 range of 95% to 100% doesn’t apply. These individuals should always consult with their doctor for information on acceptable oxygen levels for their unique state of health. That being said, here are a few general guidelines on SpO2 for individuals with acute respiratory issues and chronic diseases:
● In a patient with acute respiratory illness (e.g., influenza) or breathing difficulty (e.g, an asthma attack), an SpO2 of 92% or less may indicate a need for oxygen supplementation.
● In a patient with stable chronic disease (e.g., COPD), an SpO2 of 92% or less should prompt referral for further investigation of the need for long-term oxygen therapy.
Measuring Your Oxygen Level
Today’s medical experts have access to a wide variety of SpO2 monitoring tools, including finger pulse oximeters. These compact, noninvasive devices attach painlessly to the fingertip and send wavelengths of light through the finger to assess SpO2 and pulse rate. 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. 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. Arterial blood gas measurements, obtained by arterial puncture, remain the gold standard for measurement of oxygen saturation.
A personal finger pulse oximeter is designed to be fast, durable and intuitive. All you have to do is place it on any finger and wait a few seconds for it to measure your current SpO2 and heart rate. However, not all pulse oximeters deliver the same level of performance and versatility. 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. That’s why in-home caretakers and people suffering from respiratory problems count on clinically proven self-monitoring solutions from Ltd Deals UK.
