Guest guest Posted August 21, 2009 Report Share Posted August 21, 2009 Sometimes I just like to toss out reminders, not knowing how many new people we have who haven't seen discussions on such topics. Everyone with PF should have periodic overnight oximetry tests done. It's simple. They drop a machine off. You hook up to it when you go to bed. They pick it up tomorrow. They also can do 24 hour oximetry too. This is the only way to know your saturation while asleep. It will change as you progress too. When I was diagnosed and initially checked over 25% of my sleep time I was below 90%. Think about this. No matter what I might have done during the day to keep saturated, I was spending 2 hours undersaturated every night. On 2 lpm I am only under 90% less than 0.1% of the time and only for seconds now. I was just retested and still good. My PH doctor (the one who found out I don't have PH thankfully) recommends them every six months. Nothing else you do can tell you. Not CT's, not PFT's, not checking your oximeter during the day. In addition to harming you and putting you at risk for PH, the undersaturation also greatly worsens your quality of sleep.
