Scrutable

Ok I’ve managed to ensure myself and my caree haven’t got Covid since this nightmare started but it’s only a matter of time.

Would it be an idea to get a pulse oximeter in preparation and if so what do I look out for?

Yes get one.

The absolute level can be inaccurate with cheap ones. But change in level should be close enough Calibrate it a few times during normal health.

I can guess my O2 sats from how I feel - I'm actually reasonably accurate. Lots of experience

I'd get one - though, as previously said, they won't be very accurate so calibration needed. No idea what to look for in one though. I'm old school so I gauge my hospital-neediness from whether I can count to ten in one breath and how dodgy I actually feel. As your O2 sats go down you feel more and more numb, stuff seems to matter less and your perception goes all strange. The only concern I'd have over this type of home meter is that it could be so inaccurate as to cause false alarms (or miss a real one). No matter what test you're using, the good old fashioned "do I feel like I might die without help?" test works best.

I got one very early in the pandemic. I played with it a few times. When I put it on it says 93 and I think I'm going to die, then within 10 seconds it's up to 97. With some controlled breathing I can get to 98 about a third of the time. The game ends when I score a 99.

I remember having one on my finger when I was last in hospital. When they explained it to me I thought it was some kind of magic. It's amazing that you can get such important information from such a small, non-invasive gadget. This video is a good explanation of how it works, including a slightly subversive formula at 02:43.

Always nice to see that pulse reading falling as the O2 reading rises.
