The difference between the amount of absorption provides a fairly accurate level of your oxygen saturation. Normal readings are between 95 percent and 100 percent. A reading below 90 percent is too low and may indicate hypoxemia, or low blood oxygen. A pulse oximeter may be a helpful tool to monitor oxygen levels at home if you suspect you have Covid-19. Here's what doctors want you to know about normal oxygen levels and those that might be a.
Here are some general guidelines to understanding oximeter readings and SpO2 values.
A healthy person should be able to achieve normal blood oxygen saturation levels (SpO2) of 94% to 99% consistently. For patients with mild respiratory diseases, the SpO2 should be 90% or above. Supplementary oxygen should be used if SpO2 levels falls below 90%, which is unacceptable for prolonged periods of time.
Healthy lungs keep the blood oxygenated at a level between 95 and 100%—if it dips below 92%, it’s a cause for concern and a doctor might decide to intervene with supplemental oxygen. This is the right oxygen level and pulse rate. SpO2 levels in all healthy individuals range from 94 to 96 per cent. Anything below 90 per cent will indicate low oxygen level and the patient will require immediate medical attention as he/she can lose his/her precious life. Healthy people usually have a blood oxygen level above 95 percent. Added oxygen may be needed for people whose oxygen level falls below 90 percent and home oxygen therapy may be recommended to regain normal levels. When oxygen saturation drops below 80 percent, severe hypoxemia occurs. Hypoxemia is a low level of oxygen in the blood that.
The blood oxygen level and the pulse rate, to a degree, are affiliated with each other but there is no strict direct correlation between the two. For example, a baby, a teenager a young adult and an elderly person in good health should all have a blood oxygen level of 94 or higher but the pulse in a baby can be 115 beats per minute while the other three people can average between 60 to 72 beats per minute. When you consider other variables like diet, and exercise regimen the range difference in pulse rate between people can be even more dramatic. A good example of such dramatic variations is marathon runners. Marathon runners can bring their pulse to as low as 35 beats per minute while maintaining a blood oxygen level of 97% or higher. This is due to the great conditioning of their bodies which makes the blood circulation so efficient that their hearts work very little to circulate the same amount of blood compared to non-runners.
Your Blood Oxygen Normal Values are dependent on your health condition, respiratory rate, percentage of oxygen in the air, activities you are performing, and other factors. Medical conditions like COPD, Asthma, Pneumonia, Lung cancer and cancer treatments like chemotherapy, smoking habit or vaping can affect the lungs capacity to transfer oxygen to the blood, thus bringing down your blood oxygen levels in a permanent way. For more details and answers to your questions visit your doctor's office.
Medicare will pay for oxygen therapy and oxygen equipment if your SpO2 readings are below 88%. If your blood oxygen saturation falls under 88% consistently, consult with a doctor immediately. Many doctors want their patients to have their SpO2 above 90%.
Sleep apnea may affect your SpO2 level. In fact, monitoring your SpO2 level while sleeping is a good way to measure your condition. To learn more about Screening for Sleep Apnea, visit Screening Sleep Apnea with Pulse Oximeters
Recently we have learned that Finger Pulse Oximeters are becoming an essential tool for detecting early Covid-19 caused Pneumonia in patients, even when they are not showing pneumonia symptoms, as reported by Doctor Richard Levitan in The New York Times article The Infection That�s Silently Killing Coronavirus Patients
What Is A Dangerous Oxygen Level
When tracking your oxygen levels in your blood pay attention to the trend. If you see anything unusual, it is time to consult your friendly doctor.
Under certain special conditions, a pulse oximeter may not give accurate results. You need to be aware of these limitations when interpreting the result.
Regardless of the reading, one should treat the patient first. The reading is only one of several important assessment criterions. Watch for symptoms of hypoxia or hypoxemia. Furthermore, pulse oximeter measures oxygen saturation, not breathing and does not indicate the removal of carbon dioxide from blood. Along with SpO2, one needs to record the respiratory rate to get an indication on breathing. If the patient is having supplementary oxygen, track the amount of oxygen also.
Take appropriate actions if the patient is not feeling OK. Emergency care may be required.
Monitor your pulse rate along with your SpO2. They are predictors of health problems. If you have abnormal readings even for a short period of time, see a doctor. Low or high pulse rate can indicate heart problems.
According to Dr. Fred Furgang in his article 'Hypoxia, Oxygen, and Pulse Oximetry,' a pilot should use supplemental oxygen if the oximeter reading is below 90%, maintain at 91-92% level when doing remedial tasks and above 93% with increased workload.
The amount of oxygen in the air, which decreases at higher altitude, would have a significant effect on a person's SpO2. A person may have a reading of 98% at sea level; it may decrease to 95% at 5,000 ft. and further to 90% at 10,000 ft. At altitude above 10,000 ft., a person may fail to adjust to the low level of oxygen and his SpO2 may drop below 80% resulting in hypoxic conditions.
Oxygen saturation refers to the amount of oxygen that’s in your bloodstream. The body requires a specific amount of oxygen in your blood to function properly. The normal range of oxygen saturation for adults is 94 to 99 percent. Anyone with an oxygen saturation level below 90 percent will likely require supplemental oxygen, which is prescribed by your primary care doctor or pulmonologist.
A Deeper Look at Oxygen Saturation
On a deeper level, oxygen saturation refers to the degree to which the hemoglobin in your red blood cells has bonded with oxygen molecules. Oxygen in the bloodstream comes from your lungs and is taken in when you inhale.
There are two common ways of measuring oxygen saturation: an arterial blood gas (ABG) test and a pulse oximeter. Of the two, the pulse oximeter is more commonly used.
The ABG Test

An ABG test measures the amount of oxygen and carbon dioxide present in the bloodstream and can be used to help diagnose COPD. It can also determine the acidity, or pH, of your blood. When you inhale, oxygen flows into the blood and is carried via red blood cells throughout your body. Carbon dioxide, on the other hand, flows out of the blood and back into the lungs. An ABG test can reveal how effectively your lungs bring oxygen into the bloodstream and remove carbon dioxide from the bloodstream.
An ABG test takes only a few minutes to complete and requires a small blood sample. Once drawn from the body, the blood sample is analyzed in a portable machine or laboratory. The blood sample must be analyzed within 10 minutes of extraction to ensure an accurate reading.
Test results for people with COPD will reveal a decrease in pH and oxygen in the blood, and an increase in carbon dioxide. A recent study, however, found that continuous COPD treatment can slow the progression of decline in these areas and can also help reduce the number of exacerbations.
The Pulse Oximetry Test
A pulse oximeter clips onto your finger and indirectly measures oxygen saturation. It shines light beams into the blood circulating in your capillaries, which reflect the amount of oxygen in the blood. Pulse oximeter readings are expressed as a percentage. As stated above, a reading of 94 to 99 percent or higher indicates normal oxygen saturation, and anything below 90 percent is considered to be low blood oxygen, also known as hypoxemia.
What can I do about my Oxygen Saturation Level?
If you have low oxygen saturation, the good news is that you can work to improve your oxygen saturation levels. Using supplemental oxygen, eating healthy foods and regular exercise are three ways to directly improve your blood oxygen saturation levels.
3) Exercise
Regular exercise may also improve oxygen saturation levels. A recent study conducted on rats found that regular exercise actually reduced the negative effects of hypoxemia. If you’re new to exercise, read our lung exercise blog post for some great tips on how to get started. Exercising is one of the best things that you can do for your lung health. Just remember to talk with your doctor before starting or changing your exercise routine.
2) Healthy Eating
Healthy eating also plays an important role in blood oxygen saturation. Eating meat and fish ensure that you have enough iron, as low iron levels are a common cause of low oxygen saturation. If your iron levels are low, try incorporating foods such as canned tuna, beef or chicken into your diet.
If you’re a vegetarian or prefer to not eat a lot of meat, you can still get iron from plant sources. Kidney beans, lentils, tofu, cashew nuts and baked potatoes are great sources of iron. While these foods contain iron, it’s a different type of iron than you will find in meat products. Because of this, taking supplements like vitamin C or eating citrus fruits and iron-rich vegetables will help your body boost iron absorption.
1) Supplemental Oxygen
Supplemental oxygen could have the most significant direct impact and is prescribed by your primary care doctor or pulmonologist. Some people require supplemental oxygen 24 hours a day, whereas others use supplemental oxygen only as needed. Your doctor will be able to best direct you on flow settings and frequency of use.
Some Lung Health Institute patients have experienced an improvement in blood oxygen saturation after receiving cellular therapy. If you’re interested in learning more or would like to know if you’re a candidate for treatment, contact us today.
