well, I am making strides, (so to speak) but out of sequence.
climbed a phone book on monday, tuesday a full 7 inch step up and today four full up and downs - that's my back porch steps....
but that's at bedside, not taking any hikes with my walker yet, as I am tethered to a R2D2 like LOx tank.
(in fact, on Star Wars IV, Jawa crawler scenes, there may be one or two as set dressing.)
by now I "wanted" to be on room air.....
today or tomorrow my own personal oximeter arrives, giving me better monitoring access to my condition.
i had an old school oximeter i was slowly interfacing to a computer, but this one actually has a USB interface and 30 hour study memory
for a shockingly low price - well under a hundred bucks, complete with "study" software!!!
