Oxygen in the blood

Pulse oximetry is an easy way to measure the saturations of oxygen in arterial blood.

Dr Campbell is making America smart again, thanks Doc.

I am really enjoying your videos. I bought one of these a while ago. Pre-pandemic, in January 2020, I had double pneumonia with loss of taste/smell, cough, low-grade fever, and body aches. When I went to the doctor, my oxygen saturation read 91%! She put me on antibiotics, inhalers, steroids, high doses of Vit C and Vit D and had me come back in 5 days to listen to my lungs again. Five days later, my oxygen was at 92%. And continued to climb as I got better. I am 100% sure this was covid before we knew about it and my dr also agrees. Had it been the pandemic when I walked into her office, she would have had me admitted to the hospital immediately and I fear that I wouldn't have had such a positive outcome as I did with my meds and healing at home.

Hey Dr C Thank you for sharing. I'm pretty sure you know this but during your live feed today. You had close to 6k viewers, while US presidential candidates only had 1k viewers. Numbers don't lie we sincerely appreciate your videos especially when the MSM/Gov are questionable. Thank You Doc!!! , !!

This guy freaking rocks. Just wanted to say it!

Thank for the Red Cell Ghosts comment! Sometimes when I get extremely relaxed I see "bacteria" float across my vision. You solved a mystery that I have been curious about for almost 45 years!

Good to see a genuinely passionate doctor. He’s concerned. He’s educating. And he can’t help giggling every time he uses it.

Dr CAMPBELL, I don't want to be rude. But, I don't want a other caring doctor getting very ill and passing away. That happened to my dad, a primary doctor, who carred for every one else. He was working 15 hours a day (6 days a week) to save everyone else. But too busy to take care of himself.
Dr CAMPBELL you have to also take care of yourself! 💛🍀💛🍀

Thanks for the explanation Dr Campbell, I'll get one of those devices, quite like the yellow one. Many years ago I went to ER with my husband as he had had a bad fall. I wasn't feeling very well myself, very tired and short of bread. Lovely NHS nurses and doctors, they did their work as a breeze but still had time to check on you and talk in normal language. One of the nurses saw me taking air in gulps, like a fish, and asked if she could check my oxygen level. It was dangerously low and I hadn't even noticed. I was put on oxygen for several hours, I was having asthma episodes, each one worse than the previous. I didn't even know I was asthmatic at that time, I just thought I was tired and couldn't sleep in bed because of stress. I believe she saved my life. We all have to fight for the NHS and it's fantastic staff, they are selling it off bit by bit!

That was interesting. I really enjoyed this video. You have an amazing ability to explain things in a simple way.

Thank you Dr. Campbell for your time. Knowledge is helpful in reducing anxiety. Strange days.

I like the manual writing on the paper, reminds me of my teacher using the overhead projector when i was a kid

We used to live by that little gadget. Our youngest son has Cystic Fibrosis. After starting a new medication called Trikafta, his blood stats have gone from 75% on a good day (with hospitalizations for 35-50% every few weeks) to a steady 98%, and no further hospitalizations. Truly a modern miracle.

Great explanation, my elderly Aunt has CPOD and is in hospital now.. Yesterday her saturation level was going down to 85 and yes she was looking very ill! Today went to visit her and she was sat up eating biscuits! I couldn't believe the change and was nice to talk to her, as yesterday I thought I'd never have a conversation with her again!

Best honest, reliable, compassionate, doctor providing hope to everyone. I feel like no one understands us humans who do not believe the "information" from mainstream media. I lost all my friends and others who don't understand. Thank you Dr Campbell

[cahuman]

Thank you Dr Campbell for the awesome videos that you produce. You truly are a great educator🌴

[vijfacht]

My GP lent me one of these nifty machines - She was like, if it goes under 95% get in touch. Such a comfort to have a tool that's so helpful

[valeriebadger]

I self isolated due to a lung condition( Bronchiectasis) which is managed with Yoga and medication. I purchased an Oximeter so I could check my levels. Self help is what we all need. Thanks for your interesting videos. I paid £6. last October for mine.

[SN-blxm]

Dr Campbell, you are awesome. You remind me a lot of my dad, who was a primary doctor. My dad took very good care of his patients and everyone else. Unfortunately he was to busy to help everyone else and didn't take care of himself. He got very ill and passed away 5 years ago.
Dr Campbell, please don't forget to take care of yourself! We all highly appreciate the information you share with us. You are helping thousands of people with your videos. But we all want you alive.
Take care! 💛🍀

As a an asthmatic I've received more info here than any doctor has told me collectively in my 37 years about oxygen levels and hypoxemia. Cheers Dr John you're an absolute legend by teaching us all. I'm going to Tokyo (my 2nd home outside NZ) in two weeks and I rapidly develop chest infections even with general colds and influenza so hence bit nervous but all your info goes a long way. Thanks again.

I'm glad I purchased one of these little gadgets last year. It became very handy when my wife caught this thing going around. Happy to report she's up to 96 today. Cheers!
