My diag code on my O2 equip was for acute sleep apnea. Well when I switched equipment suppliers, the nurse at mu docs threw a hissy fit; next thing is the equipment was jerked w/o leaving me with adequate service, which is against thelaw! So the local provider I requisted taked to the doc yesterday and the doc told him the apnea wasn't the MAIN reason for the CPAP, O2 canisters et al, it was hypoxia! Anyone know what the hey? Cactus.
