Can stress cause low oxygen levels?

It works like this: Momentary stress causes the body to tense and you begin to breathe a little more shallowly. A shallow breath lowers oxygen levels in the blood, which the brain senses as stress. Breathing then becomes a little faster and shallower. Oxygen levels fall a little more.

How can I check my oxygen levels at home?

Using a Finger Pulse Oximeter, which is a small device that is attached to your finger to measure the amount of oxygen in the blood travelling round your body. The Oximeter takes an SpO2 reading – an estimation of the amount of oxygen in your blood.

What is the correct oxygen level?

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.
