What Is the Normal Oxygen Level for the Elderly? The normal oxygen saturation level is from 97 to 100%. Older adults usually have lower levels of oxygen levels as compared to younger adults. If a person is older than 70, a normal oxygen level could be around 95% instead.
People over 70 years of age may have oxygen levels closer to 95%. Normal oxygen saturation levels (SpO2) are between 95 to 100 percent for both adults and children. Oxygen saturation levels below 95% are considered abnormal, and the brain may be affected when SpO2 levels drop below 80 to 85 percent.
A normal oxygen saturation level ranges between 95 percent and 100 percent. Saturation levels may be somewhat lower and considered acceptable if you have a lung disease such as COPD or pneumonia.
A healthy blood oxygen level varies between 75 and 100 millimeters of mercury (mm Hg). When arterial blood gas (ABG) test results reveal an oxygen level below 60 mm Hg , the medical community considers it low. In some cases, people with these results may require oxygen supplementation.
Your blood oxygen level is measured as a percentage—95 to 100 percent is considered normal. “If oxygen levels are below 88 percent, that is a cause for concern,” said Christian Bime, MD, a critical care medicine specialist with a focus in pulmonology at Banner - University Medical Center Tucson.

People with oxygen levels below 95% must take medical advice immediately. Oxygen level below 90% is very concerning, indicating a medical emergency. The state is termed hypoxemia. Immediate medical help must be given to the person.
90% or less This oxygen level is very concerning and may indicate a severe medical problem. Call 911 or go to the nearest emergency room immediately.
A normal level of oxygen is usually 95% or higher. Some people with chronic lung disease or sleep apnea can have normal levels around 90%. The “SpO2” reading on a pulse oximeter shows the percentage of oxygen in someone's blood. If your home SpO2 reading is lower than 95%, call your health care provider.
Make sure you have been resting for at least five minutes before taking the reading. Rest your hand on your chest at the level of your heart and hold it still. Switch the pulse oximeter on and place it on your finger. It works best on your middle or index finger of either hand, it should not be used on your ear.
If you have a health condition that causes low levels of oxygen in your blood (hypoxia), you may feel breathless and tired, particularly after walking or coughing. Fluid may also build up around your ankles (oedema) and you may have blue lips (cyanosis).
Vital Signs in Loved Ones: Pulse
Normal Heart Rate for Elderly: 60 to 100 beats per minute.
When you drink lots of water, your lungs remain properly hydrated, which improves their ability to oxygenate and expel carbon dioxide. Therefore, the oxygen saturation level of your body gets improved. Also, drinking 2-3 litres of water may improve your blood's oxygen saturation level by up to 5 per cent.
You should drink beetroot juice and carrot juice in addition to drinking plenty of water daily to improve your oxygen levels. Beetroot and carrot contain iron which boosts the production of haemoglobin, the blood's oxygen carrier.
Some of the most common causes of low blood oxygen levels (hypoxemia) include: Heart conditions. Lung conditions such as asthma, emphysema, and bronchitis. Strong pain medications or other problems that slow breathing.
Shortness of breath does not equal saturation (SaO2%)
In other words, your level of dyspnea, or air hunger, does not always correlate with your oxygen saturation. This means that you can be short of breath, even extremely short of breath, even in the presence of normal oxygen saturation.
A person may have dyspnea even though the actual levels of oxygen are within a normal range. It is important to understand that people do not suffocate or die from dyspnea. But tell your health care team right away if you have any of these symptoms or if they get worse.
So, back to the original question – does blood oxygen level drop during exercise – yes it does, simply because of the extra demands of the muscles. When you're not exercising, the oxygen saturation level is between 95% and 99%.
"Foods that are rich in iron and nitrates are the key to increasing oxygen supply throughout your body. So, beetroot, leafy vegetables, pomegranate, garlic, cabbage, cauliflower, sprouts, meat, nuts and seeds help.
Most people will die within 10 minutes of total oxygen deprivation. Those in poor health often die much sooner. Some people may suffer other medical catastrophes, such as a heart attack, in response to oxygen deprivation.
