Dec 21, 2022 · Blood oxygen levels (arterial oxygen) indicate the oxygen levels present in the blood that flows through the arteries of the body. Normal arterial oxygen pressure (PaO2) measured using the arterial blood gas (ABG) test is approximately 75 to 100 millimeters of mercury. Understand levels, chart, and hypoxemia.

Jun 13, 2024 · In most cases, your healthcare provider will give you a target blood oxygen level to maintain. Your home oxygen device will have a dial to adjust the amount and flow of oxygen you receive. Your healthcare provider may recommend an amount to use or to change the amount of oxygen you need to reach a particular range on your blood oxygen reading.

If oxygen concentrations fall between 91% and 95%, it is a cause for concern. This signifies an underlying medical problem and it is advised that if you have a reading in this range, that you contact your healthcare provider.
Low blood oxygen rateis medically defined as percentages that fall below 90% oxygen saturation. In short, readings at this level indicate a medical emergency. You should call 911 immediately if blood oxygen saturation falls this low
If a patient’s oxygen saturation level falls to 85% or below, the brain is being adversely affected due to lack of oxygen. Symptoms include vision changes or loss of vision and total blackout.
If blood oxygen saturation levels fall to around 67%, Cyanosis will set it. The lack of oxygen being transported by your blood cells, causes a blue tinge to develop on your skin. Your mouth, lips, and beneath your fingernail matrix will be affected first, followed by the spread occurring over the rest of your body.
Understanding blood oxygen saturation levels is very important when using a pulse oximeter at home. If you take a reading lower than 95% you now know that action does need to be taken.
Sep 13, 2024 · Turn on the pulse oximeter and place it on your fingertip, ideally the middle or index finger. Sit still and avoid moving while the device reads your oxygen levels and heart rate. The screen will display your oxygen saturation level (SpO2) and pulse rate within seconds. Ensure the reading is stable for 30 to 60 seconds before removing the device.
Jun 29, 2023 · A healthy blood oxygen level is 75–100 mm Hg, or 95–100%. Low blood oxygen levels, known as hypoxemia, may be a cause for concern.
People over 70 years of age may have oxygen levels closer to 95%, which can be normal for that age group, while normal SpO2 rates for infants and children are usually 97% and higher. Low levels of oxygen in the body’s tissues are called hypoxia. Low levels of oxygen in the blood are called hypoxemia.
