Oxygen and Brain Damage

Oxygen and Brain Damage

Oxygen is essential to a properly functioning body. In fact, the brain requires a constant supply of glucose and oxygen. However, if you have a chronic lung disease such as emphysema, pulmonary fibrosis or COPD, having enough blood oxygen can be challenging. Lack of oxygen to the brain can cause brain damage in minutes. When the brain does not receive enough oxygen, cerebral hypoxia can occur. Here’s what you need to know to help you better understand the risks of low oxygen and brain damage.

What is cerebral hypoxia?

Also known as brain hypoxia, cerebral hypoxia is a serious medical condition. The symptoms of cerebral hypoxia can be mild to severe and include poor judgment, decline in cognition, uncoordinated movement, pupils that do not react to light, respiratory failure and complete unawareness and unresponsiveness.

Cerebral hypoxia requires immediate emergency treatment to return the flow of oxygen to the brain. If you suspect cerebral hypoxia, call 911.

What are the risks and causes of low oxygen and brain damage?

The brain uses about 25 percent of your oxygen intake, so avoiding low oxygen and brain damage is important. Because cerebral hypoxia can occur from a lack of oxygen to the brain, it’s important to supply your brain with enough oxygen. Cerebral hypoxia can be caused by smoke inhalation, carbon monoxide poisoning, choking, cardiac arrest, drowning, stroke and other conditions.

Breathing and blood flow to the brain.

Oxygen and Brain Damage

Every time you breathe, gases exchange in your lungs. Beginning with the nose and mouth, the respiratory system is made up of organs and tissues that allow people to exchange oxygen and carbon dioxide. The airways are the pipes that carry oxygenated air into the lungs and carbon dioxide out. Inside the airways are tiny hairs called cilia, which are coated with sticky mucus to trap germs and other foreign particles to prevent them from entering the airways.

The lungs are linked to blood vessels that deliver oxygen and remove carbon dioxide. The bronchi inside the lungs branch into smaller, thinner tubes called bronchioles, and these tubes end in bunches of tiny round air sacs or alveoli. The alveoli are covered in capillaries. Once inside the air sacs, carbon dioxide moves from the blood and into the air to be exhaled, and oxygen moves from inhaled air into the capillaries. Now, oxygen-rich blood travels to the heart through the pulmonary vein and its branches and on to the rest of the body.

When you have a chronic lung disease, what happens to the oxygen?

Your lungs must inhale oxygen-rich air and exhale carbon dioxide effectively in order for you to receive enough oxygen. The circulatory system moves blood through the lungs where oxygen is absorbed and carried throughout the body. People with chronic lung disease may have trouble breathing, and therefore, absorbing enough oxygen. One of the common symptoms of lung disease is low blood oxygen levels. When your blood oxygen falls below a certain level, the result is called hypoxemia. The symptoms of hypoxemia include extreme shortness of breath, headache, confusion and restlessness.

How can I improve my oxygen levels?

Oxygen and Brain Damage

While there isn’t 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 you’ve gained more knowledge about oxygen and brain damage to help you stay informed. We’re happy to answer your questions regarding cellular therapy options. If you or a loved one has a chronic lung disease like COPD or pulmonary fibrosis and would like more information, contact us at (800) 729-3065.

    We are encouraged to hear you want to pursue cell therapy treatments with the Lung Institute. Innovations in the field of regenerative medicine are newer and emerging in medical technology. Currently, the highly specialized methods are not taught in traditional medical schools or residency programs. At the Lung Institute, our advanced procedures are specialized, and our physicians receive additional training for the best quality of care for our patients. There are patients who have not seen great improvement, but 84 percent of our patients note an improved quality of life three months after treatment.

    We’re happy to answer your questions about cellular therapy, so feel free to contact us at (855) 313-1149 to speak one-on-one with a patient coordinator. We look forward to hearing from you soon.

    Have been talking with Lori about plans to take treatment with bone marrow for copd. during my 6 month Appointment Dr. Garfinkle, my pulmonol;ogist”s nurse elaine said to me when talking about fuure visit to dallas tx.for bone marrow therapy that two(2) of their patients had just returned from that location. there is no indication of success of treatment she(elaine) said. my question is:. How long does a person after bone marrow treatment til a person health problem begins to feel and show improvement. dr garfinkle said science has not shown that this is improving lung issue diseases. he said this when i said 84.5% of patients treated have some kind of improvement at the lung institute . i have read great comments of some stating their activities of everday life and health have improved, some are now not using oxygen equiptment and doing things again that they have not been able to do in a while etc. Thank You Betty L. Tulsa ok.

    Dear Hemalatha,

    Thanks for your comment and questions. First and foremost, we’re sorry to hear that you have been going through such a challenging time with heart disease, pulmonary arterial hypertension and peripheral neuropathy. At the Lung Institute, we treat patients with a variety of chronic lung diseases, such as COPD, emphysema and pulmonary fibrosis. Because of the complexity of your personal health situation, we recommend contacting us at (855) 313-1149 so that we can discuss your situation in a confidential, one-on-one setting. Our patient coordinators have a wealth of knowledge about cellular therapy, and they are happy to answer your questions. We look forward to hearing from you soon.

    Kind Regards,

    The Lung Institute

    I have a congenital heart disease, pulmonary arterial hypertension, secondary to pda. I have been on tadalafil, warfarin, ivabradine and digoxin. I also take 1.5 ltrs of nocturnal oxygen. I am 41 years old. Now, due to long term hypoxia, I have developed peripheral neuropathy. My question is,
    1. Can cell therapy cure my pah?
    2. Will it also reverse my neuropathy?
    Appreciate your reply.
    Thank you.
