Blood Oxygen Level: What It Means to You

For people with chronic obstructive pulmonary disease (COPD), emphysema, pulmonary fibrosis and other chronic lung diseases, keeping a close eye on their blood oxygen level is typically part of the daily routine. However, for people living with COPD and other chronic lung conditions, receiving enough oxygen can be challenging. Every cell, organ and tissue in your body needs adequate oxygen, so oxygen is essential to a properly functioning body. When your body doesn’t receive enough oxygen, it’s unable to function properly. We’re here to help you better understand your blood oxygen level, how your body gets oxygen and what it could mean for you.

Oxygen and the Body

Your body uses oxygen in various ways to keep you at your best. Your blood transports oxygen throughout your body. Your body contains many different types of blood vessels, which act as the road system for your blood to travel throughout your body. Oxygen-rich blood travels through arteries and arterial branches to deliver oxygen and essential nutrients to your body. Capillaries are small, thin blood vessels that connect arteries and veins. Capillaries are important because they allow oxygen, nutrients, carbon dioxide and waste to pass to and from the tissue’s cells. Oxygen-poor blood travels through veins back to the heart and lungs where it will be re-oxygenated.

Your heart and lungs work together to deliver oxygen to your body, and your lungs inhale oxygen-rich air and exhale carbon dioxide. The heart pumps your blood to your lungs, so your blood can become oxygenated. Then, your heart pumps the oxygenated blood through your arteries and sends your blood to deliver oxygen to other cells, organs and tissues in your body.

How Your Heart and Lungs Deliver Oxygen Step-by-Step

Your heart has four chambers and four valves, which work to pump blood throughout your body. Your lungs and linked blood vessels deliver oxygen and remove carbon dioxide. The bronchi inside the lungs branch into smaller, thinner tubes called bronchioles. These tubes end in bunches of tiny, round air sacs called alveoli. Alveoli are covered in capillaries, and these capillaries connect to a network of veins and arteries.

The pulmonary artery and its branches deliver oxygen-poor blood to the capillaries that surround the air sacs. Once inside the air sacs, carbon dioxide moves from the blood and into the air to be exhaled while oxygen moves from inhaled air into the capillaries. Oxygen-rich blood then travels to the heart through the pulmonary vein and its branches, and on to the rest of the body.

Here’s How Oxygen Is Moved Through the Heart and Lungs to the Body:

Blood Oxygen Level: What It Means to You

Your Blood Oxygen Level and What It Means

A healthy, normal blood oxygen level remains around 95 percent to 100 percent. You can monitor your blood oxygen level at home with a pulse oximeter. Values below 90 percent are considered low.

When your body doesn’t receive enough oxygen and you have a low blood oxygen level, hypoxemia or hypoxia, cyanosis and other conditions may occur. Because COPD and other chronic lung diseases restrict or obstruct normal breathing, low blood oxygen levels can be a serious issue. Hypoxemia or hypoxia occurs when your body has insufficient oxygen and can range from mild to severe. Symptoms of hypoxia can include severe shortness of breath, wheezing, constant coughing, a choking feeling and a bluish discoloration of the skin (cyanosis).

Chronic hypoxia can lead to cerebral hypoxia or brain hypoxia, which means that your brain cells could become seriously damaged within minutes.

If you suspect hypoxia call your doctor immediately. For cerebral hypoxia, call 911.

Improve Your Blood Oxygen Level

Many doctors will prescribe oxygen therapy to help you receive enough oxygen and to improve your blood oxygen levels. Your doctor may also prescribe breathing exercises, diet and exercise changes, pulmonary rehabilitation and medications to help you breathe. Keeping a close eye on your blood oxygen level is important as well. Remember to see your doctor regularly even if you’re feeling well, so you and your doctor can work together.

In combination with traditional treatments, many people with COPD and other chronic lung diseases have seen improvements to their pulmonary function after stem cell therapy. A relatively new treatment, stem cell therapy works to promote healing from within the lungs, potentially improving lung function. In fact, many patients report coming off or significantly reducing their oxygen therapy use after treatment. If you or a loved one has COPD, emphysema, pulmonary fibrosis or another chronic lung disease and would like to learn more about your options, contact us at (800) 729-3065.

    Tom:

    Thank you for your comment and we are sorry to hear about your condition.

    As you noted in your message you are hoping the medications you are taking will put your IPF “on hold.” That is what traditional medications do, they help you manage your symptoms for a while, but they are not addressing your disease.

    Our treatments actually try to slow the progression of the disease so you can have a better quality of life and a chance to not need medications.

    Our dedicated medical team has a wealth of knowledge about stem cells, treatment options, candidacy, cost and more. We’re happy to answer your questions, so feel free to give us a call at (855) 313-1149. We look forward to hearing from you soon.

    Sincerely,

    The Lung Institute

    I Have been diagnosed with Idiopathic Pulminary fibrosis and currently waiting to go on the medication ofev shortly. i was unable to start this therapy as my metabolic panel blood test indicated an ast (sgot) reading level of 50 and was told that the medication would not properly metabolize in my system if taken. I had been taking 20mg generic lipitor once daily which is a statin drug and may have contributed to this high reading. The dosage was changed to 10mg daily and i took it upon myself and started taking milk thistle 250mg (3 times a day) and Turmeric curcumin 500mg (1 daily) and after 3 weeks my ast reading dropped to 26 (range of 0-40) ! i am now able to start taking ofev and i’m hoping this drug will put my ipf on ‘hold’ in the future. i have a oximeter and my oxygen level is averaging 96-98 with a normal pulse rate. I am a 75 year old male.

    Thanks for your comment. Please speak with your physician about supplemental oxygen, who will be able to guide you in the right direction. We provide information to help you learn more about your condition and options, however for medical advice and prescriptions it’s always best to check with your physician.

    My Oxygen levels had been 92 normally and dropped to 89 occasionally before stem cell therapy. 4 weeks after “booster” stem cell treatment, one year after full treatment, I noticed for the first time ever, my blood oxygen went to a of high 97% and then 98% for the first time ever, and it was even during walking. Now 94-95 seems to be quite normal now. In addition to the stem cell therapy I began a walking program that now after 6 weeks has increased to 6 miles per day at about an 18-min/mile. I never dreamed I could do that since my first attempt to walk was 1 mile, which took me 26 minutes at a casual stroll. Now, at periods during the walk I often experience several minutes of “easy” breathing, which have been increasingly frequent as time goes on. I am alpha-1 deficient (ZZ) and get weekly Prolastin infusions that halts the progress of lung disease, I receive stem cell therapy every 3-4 months, which heals inflammation, increases blood oxygen and making breathing easier, and I supplement with L-argenine which contributes to healthier, more elastic vascular system.
