- Normal Oxygen Level in Blood. For most people, an oxygen level of 95-100% is considered to be normal. When the level of oxygen is within this range, it is considered to be optimum for smooth functioning of the cells. A level that is below 95% is a cause for concern and warrants an examination or testing by a medical personnel.

Understanding your oxygen saturation levels is the key to better respiratory health.
Various right-wing Twitter accounts have recently been pointing to testimony from the Derek Chauvin trial, in which an expert for the prosecution pointed out that George Floyd's oxygen saturation w.
When it comes to living with a chronic lung disease such as chronic obstructive pulmonary disease (COPD), pulmonary fibrosis or emphysema, understanding one’s disease and all the metrics that influence it are critical to managing one’s health. These metrics can be lung function, lung capacity and blood oxygen saturation levels.
So, what does blood oxygen saturation actually mean? In short, blood oxygen saturation is the amount of oxygen within a blood cell. The importance of this concept rests on the fact that higher levels of blood cell oxygen saturation will ultimately permit easier breathing and reduced shortness of breath. Though the symptoms of COPD and other lung diseases can be addressed through a variety of natural treatment options, understanding one’s personal health is imperative to health management and decision making moving forward.
With your health in mind, the Lung Health Institute is here to give you the information you need on Oxygen Saturation Levels: What Do They Mean, and What Can You Do?
Oxygen Saturation Levels: What Are They?
As we mentioned, oxygen saturation levels are the amount of oxygen your blood cells retain. To put this in perspective, imagine a subway network. The tunnels are your veins, the subway train is your blood, the individual cars are your blood cells and the people inside are oxygen. As the subway train travels from station to station spreading oxygen throughout the body, oxygen saturation represents the amount of oxygen (in this case people) that are within each car.
Under the best case scenario, each individual car is packed full of people. However, for those with COPD and other lung diseases, these cars can be a bit lighter than normal, or perhaps some of the cars are empty. In this sense, oxygen saturation levels show how efficiently your body is utilizing oxygen and can be used to give insight on its delivery throughout the body.
What Do Oxygen Saturation Levels Mean?
As a predictor of how oxygen-rich your blood cells are, oxygen saturation can be a key identifier in your respiratory health. This data can be instrumental in determining when to get help as the oxygen saturation level (measured as SpO2 or SaO2) can serve as a direct comparison to more standard, healthier saturation levels.
What Can You Do About Oxygen Saturation Levels?
Although a low blood oxygen level can have varying effects on your health, it is possible to improve your blood oxygen levels through direct means. For starters, the use of supplemental oxygen can temporarily have an effect on oxygenating your blood cells to improve their capacity to retain oxygen. Further still, the foods you consume can have a significant effect on increasing the available oxygen your blood cells can use. By making subtle changes to your diet, improving your body through exercise and using supplemental oxygen when needed, it’s possible to lift your blood oxygen levels and ultimately reduce feelings of shortness of breath.
Although your blood oxygen saturation levels are directly correlated with your feelings of shortness of breath, immediate treatment is critical to slowing the progression of the disease itself while bringing symptom relief. Although traditional treatment options and surgery can address disease symptoms and disease progression, they are not without their risks. While cellular therapy is novel in its use, it has shown significant effects in treating symptoms as well as disease progression, serving as a natural alternative with nearly zero adverse side effects.
Moving Forward
The best treatment for COPD is knowledge and prevention. Though COPD can seem impossible to overcome, new discoveries are being made every day in the field of cellular research. Changing one’s diet and consistently exercising are among the best lifestyle changes one can do aside from quitting smoking. When lifestyle changes fail to improve your quality of life in the way that you may expect, it may be time to consider cellular therapy. Cellular therapy may directly affect disease progression and may improve quality of life and pulmonary function. For people with lung disease, a change in quality of life could mean the difference between missing your grandchild’s graduation and standing in the front-row.
If you or a loved one suffers from a chronic disease like ILD, COPD, pulmonary fibrosis or other symptoms of lung disease, the Lung Health Institute may be able to help with a variety of adult cellular therapy options.

Oxygen levels and Covid-19
Vital signs, those fluorescent green numbers that beep, ding, and dash across black screens on the monitors in hospital rooms, have become a new source of angst during the coronavirus pandemic.
One of those vital signs is blood oxygen level, and in the hospital, it's measured with a pulse oximeter. These devices are attached to your finger and use a beam of light to measure oxygen in the blood.
Patients with Covid-19 can sometimes have relatively mild symptoms and seem to be perfectly oxygenated, even while their blood oxygen levels are perilously low. As a result, they may need an emergency supply of supplemental oxygen.
Covid-19 patients healthy enough to be discharged are often sent home with instructions to self-monitor, which has triggered a demand for pulse oximeters you can buy and use at home.
The tiny devices, which range in price from $20 to $200, clamp snugly over the index finger and display the percentage of oxygen being carried around by your blood. But how accurate are they? And how do you read them?
Three doctors, all of whom were on the coronavirus frontlines during the first peak in hard-hit New York City, warn that the results and efficacy can differ from unit to unit.
The Food and Drug Administration (FDA) considers pulse oximeters to be prescription medical devices, but most of those sold on the internet or in drugstores are labeled 'not for medical use' and have not been reviewed for accuracy. Still, having a pulse oximeter on hand may come in handy, as long as users exert common sense.
98 Oxygen Level Asphyxiation
Consumers should use the devices while under a physician's care and follow up if blood oxygen readings seem to dip precipitously, especially when paired with symptoms like shortness of breath, cough, and fever.
Here's what you need to know about checking oxygen levels with a pulse oximeter at home.

The average person takes about 20,000 breaths a day. Keeping normal oxygen levels is a finely-tuned science.
'We've got to get oxygen from the atmosphere into our lungs; we've got to get the oxygen from our lungs into our bloodstream, and then we've got to get the blood to our cells, and our cells have to take out that oxygen. So, all those things have to work right for things to go well,' explains Amit Uppal, MD, director of critical care at Bellevue Hospital in New York City.
To date, Dr. Uppal says he's overseen the treatment of more than 300 Covid-19 patients, all with varying levels of blood oxygen.
What is a good oxygen level?
'Normal people who have working lungs, and all those steps are going well, their blood oxygen level will usually be 96-100 percent,' adds Dr. Uppal.
A few notches down at 94 percent, he says, will be considered 'abnormal,' but that won't necessarily be cause for alarm. 'For the vast majority of people, nothing bad will happen. Nobody's going to have a cardiac arrest with a blood oxygen level in that [94] range.'
If someone has heart or lung disease, says Dr. Uppal, those 'normal' numbers may be a bit lower. There is, however, a universal threshold that signifies a dangerous situation.
'I think anything below 90 we definitely get very concerned. When it gets down into the 80 percent range or less than 80 percent range is when really bad things can happen.'
There is a possibility an individual's oxygen levels can be too high. However, this often occurs in people who are on supplemental oxygen.
High levels can be measured via an arterial blood gas (ABG) test, which is accurate, but invasive. This is a blood test that requires blood to be drawn from the artery, which is usually done in the wrist.
This measures your blood oxygen level and can also detect other gas levels in the blood, as well as your pH, or how acidic your blood is.
What happens when blood oxygen dips too low
When your blood oxygen reading falls below that 90 percent threshold, you'll likely feel a variety of symptoms.
'It includes feeling short of breath, and increased respiratory rate. So, if you're at rest and noticing that you're having to work hard to breathe, that's a sign,' says Reed Caldwell, MD, chief of service at NYU Langone's Cobble Hill emergency department.
You could also experience cyanosis, meaning you could turn blue or gray due to the blood's poor oxygenation, or you might have confusion, adds Dr. Caldwell.
'Your brain thrives on oxygen,' says Dr. Caldwell. 'So, people can be confused—or even unconscious.'
One of the more concerning Covid-19 symptoms
Infectious disease epidemiologist Syra Madad studied and led response teams during some of this generation's most serious health crises including Ebola, Zika, and measles. But she says nothing frightens her more than Covid-19.
'From my standpoint, and all the different epidemics I've responded to, this has been something I have never seen before,' says Madad, who is the senior director of the system-wide special pathogens program at New York City Health + Hospitals.
Last fall, she asked Congress not to let a pandemic-protection bill lapse and is now dealing with the fallout as the U.S. currently has 500,000-plus deaths from Covid-19 and counting. (It's documented in a new Netflix documentary, Pandemic: How to Prevent an Outbreak, featuring Madad.)
'Some people will be perfectly fine and have no issues,' says Madad. 'And other people will come in with their oxygen saturation levels below 94, 93, 92 percent, or even lower than that. And they look perfectly fine. It's one of those silent hypoxic killers almost.'
What is hypoxemia?
When someone is hypoxic, they're experiencing hypoxia or the absence of enough oxygen inside the body's tissues to sustain bodily functions. (A similar term, hypoxemia, means low oxygen levels in the blood, rather than the body's tissues.)
Covid-19 patients with this sign have been dubbed as having 'happy hypoxia.'
Instead of gasping for air, they're texting on their smartphones. 'They're not showing the signs and symptoms like bluish lips, trouble breathing, anything like that,' says Madad. 'So you have no idea they're experiencing this symptom, and then you check their blood oxygen levels, and you realize they're at very alarmingly low levels.'
Is 98% Oxygen Level Good
In a June article in the Journal of Medical Systems, author Jason Teo further explained how silent hypoxia sneaks up on people.
'The air sacs in Covid-19 patients' lungs do not fill with fluid or pus as in normal pneumonia infections but rather the virus only causes the air sacs to collapse, thereby reducing the oxygen levels that lead to hypoxia in these patients but still maintains the lungs' normal ability to expel carbon dioxide,' wrote Teo.
He proposes that smartphone-based oximeters may one day unlock the key to more widespread early detection.
How to check blood oxygen using a pulse oximeter
Although they were scarce early in the pandemic, pulse oximeters are now easy to find. (An Amazon search returns 1,000 results.) Many are battery-powered and simply need to be turned on and placed on your index finger.
98% Oxygen Levels In Blood
Pulse oximeters display two readings—one is SpO2, which is the oxygen saturation level in your blood, and your pulse rate.
'Monitoring [with an oximeter] is OK as long as you're under the guidance of a medical physician,' says Dr. Caldwell. 'I think it could be a potentially disastrous situation to be in if people take it upon themselves to just look up the numbers on the internet and then monitor their oxygen.'
Also, warns Dr. Uppal: 'I don't think that the general public of people who have no symptoms and have not tested positive for Covid-19 need to be checking their pulse oxygen 10 times a day.'
What Does 98% Oxygen Level Mean
When to call a doctor
Early intervention could improve health outcomes for patients presenting with lowered blood oxygen. People with low oxygen levels will often require supplemental oxygen to increase their oxygen saturation.
'We know that some people are still kind of avoidant of health care because they are afraid to get Covid-19,' says Dr. Caldwell. 'And if you can't breathe, you need to be seen. And if your oxygen level is low, you need to be evaluated because your chances of a bad outcome trying to manage [while] stuck at home, it still needs to outweigh your chance of your family picking up something in a health care setting.'
Or, someone could have something other than Covid-19 altogether. 'A blood clot in your lung can give you low oxygen' notes Dr. Caldwell, 'that's something that would need prompt attention.'
Now, doctors may also suggest home supplemental oxygen, which is prescribed. Your doctor will provide specific instructions for using home supplemental oxygen to prevent any serious complications.
Preventing Covid-19
Dr. Uppal says he has had the fortune of helping some of his Covid-19-patients recover and the misfortune of saying goodbye to others. This includes longtime colleagues for whom he fought hard for.
A particularly heart-wrenching case, he remembers, was a mother and father who passed away due to Covid-19, orphaning their two young children.
Today, nearly an entire year into the pandemic, Dr. Uppal says there are far more tools in physicians' toolbox to fight back against respiratory diseases like Covid-19.
'Steroids seem to help patients who start to deteriorate. It seems to reduce the likelihood that they end up on a breathing machine or reduce the likelihood that they end up in the ICU,' Dr. Uppal says. 'Remdesivir seems to help reduce the severity in patients. And some data just came out that a drug called tocilizumab also is beneficial.'
But nothing used to treat Covid-19 is as useful as taking measures to prevent it.
'I think what I'd like to emphasize is that getting better at treating the disease once people have it doesn't make it go away.' Dr. Uppal adds, 'The thing that we're still going to have to lean on is preventing it from spreading in the first place.'
