As a medical professional with expertise in respiratory health, I can tell you that a dangerously low blood oxygen level, also known as hypoxemia, can be life-threatening. In a healthy individual, the normal range of oxygen saturation (SpO2) is typically between 95% and 100%. When SpO2 levels fall below 90%, it is generally considered low and can be a cause for concern. However, the specific threshold that is considered "dangerously low" can vary depending on the individual's health status and the context in which the measurement is taken. For instance, in some clinical settings, a level below 88% may be considered a medical emergency. It's important to note that the symptoms of hypoxemia can be subtle and may include shortness of breath, rapid heart rate, confusion, and in severe cases, loss of consciousness or organ failure.

Normal arterial oxygen is approximately 75 to 100 millimeters of mercury (mm Hg). Values under 60 mm Hg usually indicate the need for supplemental oxygen. Normal pulse oximeter readings usually range from 95 to 100 percent. Values under 90 percent are considered low.
