Justin My Sp02 relaxed sitting is around 93%. Hyperventilate a bit and it goes to 95-96. Walk around or do just about anything and it goes to 95%. Relaxed and hands a bit cold and it goes to 95%. If I am cold and body say forget keeping hands warm it may drop to 90 - a borderline reading. That doesn't mean dead - it means getting near the point when it can cause problems. The unit comes with warnings about how to use it. LOL Yes I bought one. Used sensibly it can save bothering them if anyone here gets it.
Sounds like if you ever go in they might not let you out but they do have other ways of checking oxygen levels. Whole host of other things with blood tests too. Blood markers for all sorts of things are available from simple tests. It's probably how they detect underlying conditions. Some relate to what people have done recently though. My wife had a prediabetic test a few days after she ate a bunch of grapes. The readings also increase as people get older.
Youtube nuts - no thanks. There are all sorts around. On hospital stay durations it was easy to find reports via google. It's not now. Ok the ones I have seen don't relate to Omicron but given the same symptoms needed to get treated I don't think 24hrs is on. There are a number of things they use now to speed up recovery but that short is going too far. Some older number. 80% of people who will die do so within 14days of being admitted. Survival rate following mechanical ventilation is under 50% - making antivaxers look even more stupid. It seems high pressure air breathing is seen as another method of ventilating people suggesting it's an HDU treatment.
There is no way that 3days average means there must be some one days. For instance the average age of people who die from covid is rather high but believe it or not figures in the past have built up in a triangular shape from a few at 40 and there are always some younger. At 80+ there is a big jump and some of those will be 90 or older. Some of the really older recover. The fact there is a jump makes the average look high but it hides the fact that 50's die and also more likely to spend more time in hospital anyway.
Only thing at the moment that bugs me is they do not seem to be producing the usual weekly reports. No more specific Omicron info either but studies will appear at some point.
One thing Omicron should help with is re infection. The numbers of probables run at 1% last time I saw them but in many cases sequencing info isn't available to they have had to use symptoms to some extent. The official chance of it at the moment is 0.5%. Definite re infection based on sequencing is much lower. That should be cleared up pretty quickly now.
