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.

[@jac1161]

Correct. That scenario was me...in march 2020...after very high viral load from working the frontline. I was denied because I refused the vent (USA), and I am a longhauler with a lot of blood vessel damage and was left hypoxic for months. Horror show. I was 65%-78% for months and I was not cared for when I denied their death sentence. You are RIGHT on, my dear. If this was during the plandemic, you'd likely be in a different place. Thanks be to God! Sadly, not for many who were murdered by withholding protocols that help and heal vs...

[@nicholashudson5020]

@@jac1161 what does "refused the vent" mean? Does that mean you refused to be put on a ventilator? Its confusing to me how someone can trust the medical system enough to go there for treatment, and then refuse the treatment the entire medical community agrees is the best chance to save your life. Also not sure what alternative treatments you were hoping to receive at the time, but HCQ and other things that were being tried in those early days have been proven again and again to be ineffective. Not necessarily worse than anything else people were trying, so don't see any reason to refuse to treat people who request it, but definitely not something that would have changed the outcome for you.

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!

[@justthinkingoutloud826]

******* Here are 6 tips on How to prepare: ******* 1. Living space - use an air purifier (UV, heat, or Sharp plasma technology) that kills bacteria and viruses (HEPA filter will NOT do this). The best, I think, is the plasma technology since it produces H and O2 ions that go out into the air and attack viruses and bacteria. The UV and heat air purifiers require the air to pass through the purifier in order to kill the viruses, so they will not be able to kill any viruses that are on surfaces or in air that is not circulating in the room. - air ionizers also work but produce harmful ozone which damages your lungs (so not recommended) - use a cool air humidifier (ideal humidity is between 30 - 50%) 2. If you have children old enough to prepare simple meals (open a can of soup and heat it up), teach them now how to do this. If the adults are sick, then the children will need to help out. Prepare now for ALL family members to be able to prepare food for those who are sick and unable to. 3. Have sufficient food (one month supply) that is simple, and easy to prepare. If you are on your own and sick, you will not be able to prepare full course meals, so you want easy, quick, but nutritious food. And if children are included, they need to be able to get food by themselves as well. This virus appears to hit adults harder, prepare accordingly. 4. It doesn't make sense to try to isolate a person within one home. If medical staff, in full hazmat suits, get the virus, then I would assume if one person gets the virus in your home, everyone one is exposed. Also, by the time a person is showing symptoms, most likely everyone within the family will already have been exposed to the virus. So going to the extra work of preparing a special, plastic isolation room does not make sense to me. Put your energy into more productive activities - like preparing food ahead of time. ( 5. If you have pneumonia, sleep on your stomach. This alone reduces mortality rates by 30-40% because in the prone position, lung compression is decreased, secretions drain better, and collapsed alveoli reopen. journals.lww.com/nursingcriticalcare/Fulltext/2009/05000/Prone_positioning__Improving_oxygenation_in.10.aspx digitalcommons.ric.edu/cgi/viewcontent.cgi?article=1272&context=etd 𝗣𝗟𝗘𝗔𝗦𝗘 𝘀𝗲𝗲 𝗽𝗼𝘀𝘁 𝗯𝗲𝗹𝗼𝘄 𝗯𝘆 "𝗟𝗼𝘀𝘁 𝗮𝗻𝗱 𝗙𝗼𝘂𝗻𝗱". for a much better/correct explanation!! 6. IF medical facilities become overwhelmed, then knowing what to do at home to help will be useful. Here is a medical paper on CoV19, see section "6. Treatment and Control" (go through this and highlight what you CAN do yourself. It is intended for a hospital environment, but there are still things you can do at home.) mmrjournal.biomedcentral.com/articles/10.1186/s40779-020-0233-6 (save this document so you have a copy, just in case.) - have a thermometer, and pulse/O2 reader. Take your readings now, when you are well, so you have a baseline to compare with. And do this lying down (as you would be if sick), so your baseline is a true baseline. Heart rate increases just by sitting up. - knowing these numbers will be very helpful in deciding if you need to seek medical attention. Being prepared involves body, mind and soul... the above items are how to physically prepare, being mentally prepared is also important, and don't forget your soul. Preparing to meet God is something we all have to do eventually. And He is not far away. He will hear a simple prayer for help.

The doctors told her they didn't care if she took vitamins, etc but she was NOT to take CO-Q10 because it would boost her immune system too much and interfere with the drugs used in fighting the cancer. The concentration of CO-Q10 in the body decreases as we age. Just google "CO-Q10 in body graph based on age" and look at the charts.

You may also have what are commonly called floaters. They are simply pieces of debris inside your eye. These are not red blood cells but little dots or strings that detach from your inner eye wall and float around. It’s normal and hardly noticeable for most people, but for some, they can be quite a nuisance as they are far more noticeable and can even debilitating. It’s very easy to distinguish between them. Red Cell Ghosts are fast moving, very small, numerous and can only be seen under ideal conditions like he described. They look like firework. Floaters can be numerous too or just a few, typically darker and different shapes and sizes. They usually move around slowly as you move your eye and can be seen easily depending on where they are in your eye.

If you suddenly notice a dramatic increase in the number of floaters or see bright flashes at the edge of you vision see an ophthalmologist (not optometrist) immediately. Your sight is at risk.

john thankyou so much for years I wanted to know how the oxygen sats machine worked and I have looked it up but had such complicated information bombarded I was none the wiser. well in a short space of time your diagram was all that I needed to understand this little machine. I am a nurse by the way I am 62 years old. so thankyou for your fantastic way of teaching

[@ericrichards225]

Dear Dr. John Campbell. Here is a bit of missing information from the SpO2 instruction manual. In the second half of 2016 I found that any healthy person (like me) that has a reading of 95% SpO2 reading is in fact dehydrated, *it works on the theory, when you are dehydrated the red blood cells clog together making it harder to carry oxygen.* I walked in to Auckland New Zealand hospital at 95% SpO2 and walked out the next day from a operation and ever since then the SpO2 has always been 97 to 99%. Prior to that date, I only got two reading 95% while resting and 99% while out walking. Even the nurse thought the oxymeter had gone faulty when my SpO2 jump from 95% to 98% in half a hour and went away to get another one, and sounded very surprised when she said “Oh look it is 98%” I was drinking a glass of water every 20 minutes apart from around lunch or dinner time. It took 3 liters of water to get it to jump from 95% to 98%. Now I get between 97% & 99% I can see a close relationship between *the amount of walking I do on a warm (hot) day, the amount of water I drink and the SpO2 reading on the oxymeter.* It took a lot of effort to get my story into a NZ walking magazine early 2017

[@oldbutstillcurious3615]

How much water did you drink in the half hour to caused the increase from 95 to 98%, thus amazing the nurse.

There is always a range, but hopefully most people will fall into the interquartile range so theoretically there should not be too many outliers... But when dealing with something like this, precision is key so personally (as an epidemiologist) id say it warrants at least a review of protocol...

[@jstmeand]

I bought one of these about 2 weeks ago thinking that it would help detect if I was infected with covid19 before fever since it attacks the lungs. I love your videos. My SO2 averages around 97 so while watching your video and learning how it works I started taking deep breaths and sure enough in less than a minute my SO2 got to 100%. It also made me feel great getting a oxygen high. No wonder deep breathing is so therapeutic. I'm going to do this more often to get more oxygen around the body. Thanks doc. Oh, so if someone does have covid19 would their SO2 go down enough to notice before they showed symptoms?

[@peterhodson7128]

I love Dr John’s videos and particularly his omicron variant analyses. On the blood oxygen lesson, I thought it would have been interesting to explain what happens in smokers, as it is a fact that carbon monoxide combines with heamaglobin about 20 times more efficiently than o2, thus displacing the o2 from the red cells leading to reduced blood oxygen levels. Smokers need to know this. Excellent Dr John.

[@scb2scb2]

Its not that easy i kept track of my mom's bloodpressure and o2 levels she had smoked for 50 years (a lot) and she always had a higher o2 level than me (98 or 99) while i mostly have 97 to 99) and i have never smoked. She passed away of long cancer 5 months ago.

I ordered a pulse oxymeter from Amazon and it was delivered really quickly. I was already self isolated because I'm high risk to this virus but I did have a mild cold and a bit of a sore throat - so was a little concerned that i might already have the virus. That gadget is very easy to set up and my reading for oxygenation was OK _ it's 97. This was a huge relieve. I believe the less stress and anxiety we feel the more strength we have to fight off the virus. So many many thanks to you Dr Campbell. I am so grateful for all the information you have been giving since this crisis landed in UK. PS my pulse oxymeter was made in China. Happy to be helping China out this disastrous time 😊

[@williamharlan1714]

@ Nitrogen is not absorbed into the capillaries it's just inhaled and exhaled with each breath.

@@williamharlan1714 . it's pretty interesting, then, that divers are subject to nitrogen narcosis, and also to the bends when they ascend too quickly. The latter is when nitrogen comes out of solution in the blood and bubbles out as a gas. NOW HOW DID THAT NITROGEN GET IN THERE IN THE FIRST PLACE, William?

[@williamharlan1714]

@ Good question 'Hyper'... Thanks for making me think. It was over my head but I could still reach it with my hands and pull it back down. Gas under pressure can be forced into a liquid. As you inhale a breath of compressed air at sea level it equates to a normal volume of lung capacity this is due to the surrounding air pressure(1 atmosphere). At 33 feet down the same inhaled breath is twice the sea level volume(2 atmospheres). At 66 feet the air in the lungs is 3 times the volume(3 atmospheres) compared to sea level. The water around you compresses your body and as liquids are dense and do not compress the lungs inhale more compressed air to compensate for the increasing pressures. Nitrogen at 78% volume in air under pressure has more molecules being forced into the blood plasma than other gases. As you rise to the surface the increasing lung pressure can easily be exhaled as you ascend but the Nitrogen in the plasma needs time to move to the lungs to disperse the gas into the air(in the lungs) to be exhaled. Time is necessary as the pressure on the body decreases to prevent the nitrogen from coming out of solution in the blood as bubbles. Does this clarify?

Pulse oximetry. Also used to detect Carbon Monoxide (CO) poisoning (carboxyhaemoglobin) I think.

[@jameskikuoka4863]

Andrew , actually not exactly. In carbon monoxide poisoning, the carbon monoxide binds very tightly to the hemaglobin in your red blood cells. In carbon monoxide poisoning, the pulse odometer falsely reads 90-92% when in fact, there is no oxygen carried by the red blood cells at all. That is why this situation is very dangerous.

[@nathanfrick5462]

CO content in the blood will give a false high reading as CO bonds preferentially to the hemoglobin.

[@jameskikuoka4863]

Nathan Frick , that is correct. Oxygenated hemoglobin and carbon monoxide bound hemoglobin absorb nearly, but not the same wavelength of light emitted by the pulse oximeter. Hence the false reading.
