As a medical professional, I can tell you that an oxygen saturation level of 94% is generally considered to be on the lower end of normal. Oxygen saturation, often measured as SpO2, is the percentage of hemoglobin in the blood that is saturated with oxygen. Under most circumstances, when breathing room air, a normal oxygen saturation level is between 95% and 100%. An SpO2 of 94% could indicate that the body is not getting as much oxygen as it should, which can be concerning depending on the context. For example, if you are at high altitude, an SpO2 of 94% might be expected and not a cause for concern. However, if you are at sea level and experiencing an SpO2 of 94%, it could be a sign of an underlying issue such as lung disease, heart problems, or other health conditions that affect oxygenation. It's important to note that a single reading of 94% does not necessarily indicate a problem, but if this is a consistent reading, or if you are experiencing symptoms such as shortness of breath, chest pain, or fatigue, you should consult with a healthcare provider for a proper evaluation. read more >>

Oxygen Level Too Low? My O2 saturation is 93-94%. ... Low blood oxygen, known as hypoxemia, means that the level of oxygen in the blood has fallen below normal levels, due to one or more of many different causes. Under most circumstances, breathing room air, normal readings range from 95 to 100 percent.read more >>
