Monitoring Blood Oxygen Levels Without a Pulse Oximeter

by Alan Lindemann, M.D.

I created a video to suggest how people could monitor their blood oxygen levels without waiting until they were short of breath before contacting their physicians, and hence get medical care before their COVID symptoms were severe.

In that video, I explained that shortness of breath is not an indication of too little oxygen in the blood, which is a common assumption. Shortness of breath is caused by too much carbon dioxide in the blood, not too little oxygen. BUT, if you find your blood oxygen levels dropping with a pulse oximeter, even if you’re not short of breath, you have a clear sign you need to see your physician.

But what about those who don’t have access to a pulse oximeter. There will be signs, but they are often very subtle. I saw a need to create a video suggesting what physical signs indicate your oxygen levels may be low even though you may not be short of breath.

Dr. Lindemann delivered 6000 babies for over 40 years with no maternal mortalities, no eclampsia, and no babies with cerebral palsy. He tells his story here of how he did this in a medical environment that really doesn’t do well with deliveries. He openly admits that much he learned about safe pregnancy came from his patients, not medical books. Donating here will help spread the word to women everywhere so they can learn about safe pregnancy.
