What percentage of oxygen is dangerous?
Is low blood oxygen level dangerous?
- Oxygen levels that are too low can result in muscle aches, obesity, headaches, lowered immunity, fatigue, circulation problems, anxiety, high blood pressure and depression. You may also experience more serious symptoms, including congestive heart failure, heart attack and stroke.
How do I interpret oximeter readings?
- When you keep the pulse oximeter on a fingertip, the screen shows you 2 readings on it. One is for oxygen saturation and is marked usually as %Spo2. This indicates your oxygen levels in your blood in percentage. Another reading is marked with a heart symbol or PRbpm. This reading indicates heart or pulse rate.
What is a normal pulse oximeter reading?
- 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. Theodore AC.
