Complications Of Low Oxygen Saturation

How to Manage Marginal Low Oxygen Saturation Without Oxygen Support Through Integrative Means

Low oxygen saturation in the blood can affect oxygen concentration in the body’s tissues, including the organs and muscles. This condition is calledhypoxia.

Your cells can adapt to a lack of oxygen when the deficiency is small. However, with larger deficiencies, cell damage can occur followed by cell death.

Hypoxia is often caused by hypoxemia, but may also occur when:

  • There are not enough red blood cells to carry oxygen to the tissues. Possible causes include severe bleeding due to trauma or sickle cell anemia.
  • There is inadequate blood flow. For example, a stroke occurs when there is low blood flow to a region of the brain, and a heart attack occurs when there is low blood flow to the heart muscles. Both result in cell and tissue death.
  • The tissues require even more oxygenated blood than can be delivered. Severe infections that lead to may result in hypoxemia and eventually organ failure.

How Is Brain Hypoxia Treated

Brain hypoxia requires immediate treatment to restore the flow of oxygen to your brain.

The exact course of treatment depends on the cause and severity of your condition. For a mild case caused by mountain climbing, for example, you would immediately return to a lower altitude. In more severe cases, you need emergency care that places you on a ventilator .

Your heart may need support as well. You might receive blood products and possibly fluids through an intravenous tube.

Seeking immediate treatment reduces your chances of brain damage.

You may also receive medication for blood pressure issues or to control your heart rate. Seizure-curbing medicines or anesthetics may also be part of your treatment.

How Can I Improve My Oxygen Levels

While there isnt a cure for chronic lung disease, there are ways you can help your lungs and your body feel better as well as avoid low oxygen and brain damage. Many physicians prescribe supplemental oxygen for people with lung disease. You can monitor your blood oxygen levels with pulse oximeters as well. For some people, pulmonary rehabilitation is helpful in improving lung function. Pulmonary rehab combines exercise, education and support to help people breathe and function at the highest level possible.

Eating foods that are rich in oxygen and consuming enough vitamins and minerals are other ways to increase your oxygen. Gentle forms of exercise like yoga, walking and Tai Chi, as well as relaxation and deep breathing techniques, can help improve your oxygen levels, too.

For some people, cellular therapy has helped them breathe easier by promoting the healing of lung tissue from within the body. Many patients report improved lung function and are able to come off their supplemental oxygen after treatment. We hope youve gained more knowledge about oxygen and brain damage to help you stay informed. Were happy to answer your questions regarding cellular therapy options.

How To Prevent Low Blood Oxygen Saturation

The best way to protect yourself against low blood oxygen is to avoid its causes. Keep your lungs and heart in good health by exercising regularly and eating a healthy diet. Avoid infections that can cause hypoxemia such as COVID-19 by following the recommendations of health officials. Masks help protect against many of the respiratory infections that can cause low blood oxygen levels.

Normal oxygen saturation levels drop when we sleep because we breathe more slowly. Additionally, some of our alveoli are not used while we are asleep, which means our lungs are not as efficient. Typically, doctors prefer that your oxygen level stay at or above 90% while sleeping. If your normal oxygen saturation is above 94% while you are awake, your oxygen level is unlikely to fall below 88% while you sleep, but if your doctor is concerned, they may order an overnight pulse oximetry test to be sure.

Hypoxemia: Symptoms Of Low Blood Oxygen Levels

Low blood oxygen cases often have few or no symptoms . That is sometimes even true in serious cases of hypoxemia. Some people with low blood oxygen seem well. This is why if you have reason to suspect your oxygen saturation is low, it’s helpful to have a pulse oximeter. As your oxygen saturation declines, you may begin to notice some of the following symptoms:

  • Shortness of breath
  • Feeling too unwell to do daily activities

What Are The 2 Readings On A Pulse Oximeter

The SpO2 reading should always be considered an estimate of oxygen saturation. For example, if an FDA-cleared pulse oximeter reads 90%, then the true oxygen saturation in the blood is generally between 86-94%. Pulse oximeter accuracy is highest at saturations of 90-100%, intermediate at 80-90%, and lowest below 80%.

Why Your Blood Oxygen Saturation Matters

Your red blood cells are like vehicles. Each can carry up to four oxygen molecules across your body, getting them to places like your heart and brain. Your body’s vital systems need a normal percentage of oxygen inside your blood at all times, known as your oxygen saturation. However, sometimes your blood can get either too much or too little oxygen, and in these cases, there can be serious health consequences.

    What Are The Symptoms Of Low Blood Oxygen Levels

    Photon Bio

    When your blood oxygen levels drop too low, you can experience symptoms. Specific symptoms can vary between individuals. The number and severity of symptoms will depend upon the severity of your hypoxemia and its underlying causes. Symptoms can include:

  • Headache

  • Shortness of breath while resting

  • Severe shortness of breath after physical activity

  • Rapid breathing

  • Dizziness

  • Lack of coordination

  • Left untreated, cyanosis can develop. Cyanosis can cause your skin and membranes to turn a blue color. The bluish tint usually appears on your hands, feet, lips and under your fingernails. Cyanosis indicates that your blood oxygen level is severely low. When it gets that low, it is life threatening and you should seek medical attention immediately.

    Comparison With Previous Studies

    In a recently published study , we reported a prevalence of 6.3% for SpO295% in Tromsø 6, which was lower than the 11.5% found in this study from Tromsø 5. The main reason for this difference is probably that a higher percentage was smokers in Tromsø 5 than in Tromsø 6 . There was also a higher mean age in Tromsø 5: 65.8 years compared with 63.6 in Tromsø 6. The most important predictors of low SpO2 in Tromsø 6, BMI and FEV1% predicted, were significantly associated with mortality in a multivariable model in the present study. However, survival was not significantly lower for people with a higher BMI even though a higher BMI level was associated with low SpO2. Obesity is associated with sleep apnoea , obesity hypoventilation , diabetes, hypertension, and CVD . Sleep apnoea is associated with lower daytime PaO2 even in people with normal spirometry values . After correcting for these factors, obesity itself is not associated with higher mortality. In fact, for all-cause mortality it seems to have a protective effect. Although overweight and obesity may lead to decreased oxygen saturation, the risk of premature death seems not to be increased as long as the lung function is normal and other comorbidities are adjusted for. When including other comorbidities such as CVD, hypertension, and diabetes, other studies have found that obesity, when not very severe, does not increase mortality .

    What Are The Causes Of Low Blood Oxygen Levels

    Lower blood oxygen levels or hypoxemia, a condition where the blood transports very little oxygen to other parts of the body, occur for various reasons. Low blood oxygen levels can occur due to the following reasons:

    • A general lack of oxygen in the air.
    • Difficulty breathing, thereby preventing the lungs from inhaling and circulating oxygen
    • Reduced ability of the bloodstream to circulate the oxygen to the lungs.
    • This is also due to the less intake of oxygen while breathing. This medical condition is a cause for concern and can lead to various complications within the body

    Why Does The Brain Need Oxygen

    The brain represents just 2% of a person’s body weight, yet it uses about 20% of the body’s oxygen supply. Without it, the brain can’t perform even the most basic functions. The brain relies on glucose to power the neurons that control everything from conscious functions like planning and thought to automatic, unconscious processes like managing heart rate and digestion.

    Without oxygen, the brain’s cells cannot metabolize glucose, and therefore cannot convert glucose into energy.

    When your brain is deprived of oxygen, then, the ultimate cause of brain death is inadequate energy to power the brain’s cells.

    Using A Pulse Oximeter: Things To Know

    The at-home finger meter is easy to use and gives fast results. But it also has limitations. Oxygen meters may have trouble reading your finger in some cases. According to the FDA, the accuracy of pulse oximeter readings can be affected by:

    • Wet fingers
    • Use of nicotine
    • Thick skin

    A study of COVID-19 patients in Michigan found that patients with darker skin pigmentation stand a particular risk of false pulse oximeter readings. In that study, Black patients stood nearly three times the odds of having silent low oxygen saturation that was not detected by pulse oximeters.

    What Happens When Your Oxygen Level Drops Too Low

    Breathe in. Breathe out. Along with the back beat provided by the heart, breathing is the rhythm of life. Essential to that life is oxygen. This life-supporting element comprises 20% of Earths atmosphere, and comprises 65% of your body. When your body does not have enough oxygen, serious health consequences occur.

    Each time you breathe in, you are taking oxygen into your lungs. From your lungs, oxygen attaches to your red blood cells. Through your circulatory system, your blood then delivers oxygen to every living cell in your body. Your cells use oxygen molecules to make energy and to stay alive. Without oxygen, the cells die and your organs stop functioning.

    What Questions Should I Ask My Doctor About Cerebral Hypoxia


    If a loved one has cerebral hypoxia, you may want to ask a healthcare provider:

    • How severe is the brain injury?
    • Would physical, occupational or speech therapy help?
    • Can any medications help improve symptoms?
    • Whats the long-term prognosis?
    • Should I look out for signs of complications?

    A note from Cleveland Clinic

    Cerebral hypoxia requires immediate medical care. The longer a person goes without oxygen, the greater the risk of severe brain damage and brain death. Recovery from cerebral hypoxia often involves physical, occupational and speech therapies. Your healthcare provider can connect you with resources that can aid recovery.

    What Level Of Oxygen Is Dangerous

    Only your doctor can determine what is dangerous for you, but there are some basic guidelines. Based on a standard blood oxygen level chart, an ABG measurement of 60 mm Hg or lower indicates the need for supplemental oxygen. A pulse oximeter reading under 90% is considered low and indicates the need for supplemental oxygen as well.

    So How Low Is Too Low

    7 Facts to Remember About Blood Oxygen Saturation Levels

    1. When oxygen saturation levels fall below 92%, the pressure of the oxygen in your blood is too low to penetrate the walls of the red blood cells. It is a matter of gas laws.

    2. Your insurance company may not pay for oxygen unless your levels fall to 88% oxygen saturation. This has nothing to do with what is best for you, it is just the point at which your insurance is willing to pay.

    3. Every time your oxygen level falls below 92% saturation the cells of your body are oxygen starved.

    4. When you fail to meet your oxygen needs, every organ in your body suffers the consequences.

    5. Low oxygen levels may be present only at certain times.

    • when retaining excessive fluid
    • when airways are reacting to irritants
    • with respiratory illness
    • sleep apnea
    • about 3:00am when you wake gasping for air
    • with activity when your heart muscle has become weak, though isnt technically congestive heart failure.. yet

    6. Recurring low oxygen levels are harmful and should be treated with supplemental oxygen.

    7. The problem is that your doctor may not witness your oxygen levels at 88%, and if he doesnt see that reading on an oxygen meter , then most insurance companies will not pay for it, and therefore doctors dont order it.

    Low oxygen levels are definitely something to worry about!

    If you feel you may be experiencing low oxygen levels be sure to ask your doctor to check your pulse oximetry reading.
