Thanks Lara that is great info

His previous sleep study was just a oxyometer..that records the amount of oxygen getting around the body, they just hook a wire onto his foot..he needed a print out for his home oxygen..this one will be the same except it will be to try to wean him from night oxygen..

I just wonder if perhaps there is more to his breathing than just his lungs, maybe this is another aspect..means more wires probably and probably that I can't co sleep him there..anyhow I'll try to time he stops breathing for..
