Hi all, It's been a little over 7 weeks since my original post. My machine had been behaving pretty well for the most part until a few days ago when the original symptom returned (shutting down, continuous double beep and displaying 'service needed'). I had not touched the SD card until a few days a...

Palerider - You are right. I should not have assumed any of the 750P models ever left the factory with a screw securing the silicone pressure sensor coupling. It is curious that both earlier and later models evidently have the screw. I've been in the electronics repair business for many years and ma...

Thanks for the prompt replies! Yaconsult - There was definitely no self-tapping screw there. This machine is early 2011 vintage. I'll check for the hole when my backup machine arrives. Your 550P was aptly named. 5:50 is about the time I awaken to 'P'. Baja05 - I'll try checking the clinician menu to...

To all who responded, I wish to offer my sincerest thanks for pointing me in the right direction for obtaining a backup machine and naming a reliable vendor for the eventual refurbishment my old machine will need. It's been two weeks since my original post and I'm happy to report my machine has perf...

Update - The cause of my 750P malfunction may not have been the blower at all! Skip to my Nov. 3 update below for the latest information. Hi all. I began sleep apnea therapy in 2011 with a Respironics 750P. This keeps me from being zombie-like. I have logged 13,000 hours and have been quite happy an...

Hello Pugsy,

Thanks Pugsy for letting me know about Sleepyhead data viewer. I found out I'm a real busy guy when I'm sleeping. Now if only I could figure out how to get paid for all of the activity the machine is logging.

Could that zombie-like feeling be caused by lower levels of adrenaline and other stress hormones? Was I becoming dependent on them? On the second morning of my therapy, I feel much less zombie-like and will see how the day goes. I'm only aware of waking twice last night and will know more once the s...

After the first night, I felt similar to the way I did the day after the sleep study at the St. Francis Sleep Center. It was an unusual feeling, zombie-like, knowing I had slept some but wanting to go back home and sleep for about another week. For the past 20+ years, I have been completely unaware ...

It's 9:30 Saturday morning and I just woke up from 10 hours of sleep after my second night of therapy. I see 320 transactions have already occurred on this forum prior to my waking this morning. Looks like I'm in good company. The server is limiting the size of the message I can post. The rest will ...
