Comparing Oximeters - I should have known better...

Of course - but I figured if you were a linux/BSD/xNIX user you would already have had a go at wine. Wink

... unless of course you use something _really_ obscure???

I am continually surprised at the programs people get to run in wine. I have only tinkered to see how it worked. IIRC wine is also ported to the current MacOS. I stick with windows though and use VMware to support an Ubuntu partition for the little bit stuff I do with Linux. The reverse also is commonly done with VMWare or similar making a windows partition on the xNix machine..

I started with Mini-computers in the 70's... PDP-8 and a little heard of General Automation SPC16/40
Forgive me if this is old news but...

I was interested to discover in some reading last night that optical oximeters (some at least) use two light emitters - one Infra Red and the other visible red - to sense the blood properties.

Apparently they look at the balance between the intensities of the two wavelengths as transmitted through the finger or ear-lobe to determine the SpO2.
Moriarty - the methods have become pretty standardised and work pretty well, at least we think they do - it all sort of began with some guy shining a flashlight through his hand and wondering if there could be something useful in it. I think these are some pretty clever guys.

Heck, I think the stethoscope and the reflex hammer are darned clever too. It makes my life easier, anyway. Glad I don't live back in the seventeenth century - imagine going to a proctologist back then, with candles? Ouch!
