I get it, and I don't want to hijack the thread and I want to be respectful of the views on this topic. I have medical training as do others here on this site. When you begin to start supplementing oxygen it must be remembered that you are doing so because your respiratory system in some fashion is compromised, and you are using the oxygen to make up the difference. Regarding this particular disease, you don't know if you are at the worst point or if you are going to get worse from there, and 90 is at the drop-off where we re-saturate back to the high 90's if we are intubating them. Thinking logically, if you have Covid and you are at a 90 sat level you are literally where we stop what we are doing and bag a patient because they are at a level that is too low. And if you don't know where you are in the disease progression without medical assistance you could go well below that and into a critical area. You don't want this, especially if it is preventable by going to the ER. Think on that and consider the consequences of desaturating further, especially if you are not young and in shape. There is a cascade of events that happen when you start to desat and the older you get the more dangerous and potentially permanent they could be.
Regarding the Oxygen tank: If you are at 90, what LPM are you supposed to set it at? What about 93? 85? Are you running water so that you don't dry out the nasal passages? How big is the tank and how much is in it? How long do you have with it while using the appropriate LPM? Once that's gone then what? All of this stuff is very basic, but it is also important. Oxygen is a drug.
These cats in the video got by with it because they are young and they have enough reserve capacity in their lungs to assist. I also bet that they were both tachypneic and tachycardic most of the time during this suckfest. This combination can kill an older person or one that is already compromised in either respiratory or circular system, and quicker than you think. If you have both, you're in for a rough time. Diabetics are going to have an especially hard recovery as well. Just saying grab some O2 is something I would only do in a ditch medicine situation. But If I have a hospital nearby I'm going to sending my loved ones there at the first O2 sat of 92.
I have been quite vocal here about my opinion of these "vaccines". However, the disease itself, while having a high survivability needs to be taken seriously for those with the conditions I mentioned above. Not saying you aren't taking it seriously, just saying that untrained use of oxygen may produce a certain amount of false security and allows the disease to progress too far. Not trying to be an ass either, although it may come off as that.
