What is normal oxygen level while resting?
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..
What causes high variations in blood oxygen saturation?
Frequent big variations on your estimated oxygen variation graph may indicate that you experience breathing disturbances during sleep. Breathing disturbances can lead to higher than expected variations in blood oxygen levels, which can indicate that your body is not getting enough oxygen while you sleep.
What is the lowest oxygen level you can live with?
The lower the oxygen level, the more severe the hypoxemia. This can lead to complications in body tissue and organs. Normally, a PaO2 reading below 80 mm Hg or a pulse ox (SpO2) below 95 percent is considered low.
What is normal pi %?
PI is an indicator of the relative strength of the pulsatile signal from pulse oximetry and has been found to be a reliable indicator of peripheral perfusion. PI is calculated by dividing the pulsatile signal (AC) by the nonpulsatile signal (DC) times 100, and is expressed as a percent ranging from 0.02% to 20%.
What are the symptoms of not enough oxygen in the blood?

What is the first sign of hypoxia?
The earliest signs of hypoxia are: Confusion. Restlessness. Shortness of breath.
What happens when your oxygen level drops to 80?
An oxygen level below 88% can be dangerous for any period of time. An oxygen level below 85% warrants a trip to the hospital. Keep in mind that an oxygen level 80% and lower puts your vital organs in danger, so it is important to keep a blood oxygen level chart handy so you know what levels require immediate treatment.
Can oxygen saturation levels fluctuate?
The lowest and highest mixed venous oxygen saturation values during the period were used to calculate percent changes from average values (fluctuation). Results: The range of fluctuation was +/- 6% of the average mixed venous oxygen saturation value for 80% of the sample.
