Nasal Exhale Blockage & Machine/Feature Choice
Newb here. Thanks for the forum and the wealth of information, knowledge and experience.

I have had my sleep study which indicated moderate to severe apnea. After two failed tried, my third titration study was successful. I am waiting for the sleep center to send results/recommendations to my doctor and go from there. Doing research to give me a leg up on getting the right equipment.

For the titration I used a nasal pillow and had a great night's sleep. My question is very specific. I am very aware that my obstruction is on exhale through the nose. There are two features on various machines I have read about that seem like they might be problematic with my symptoms.
  • Start with lower pressure and increase when it senses you falling asleep.
  • Reducing pressure for exhale

Regarding the first item - I have often been aware that my exhale blockage starts occurring just as I am falling asleep, thus waking me up. Seems to me I need to start out on whatever pressure will keep my airway open. Thoughts?

Regarding the second item, perhaps it is obvious. I NEED my airway to be forced to remain open during exhale, so it would seem reducing the pressure at this time would be the exact wrong thing to do. Musings?

Thanks in advance!

Hi txpap,
WELCOME! to the forum.!
It sounds like you are talking about ramp and Expiratory Pressure Relief, (EPR,) or, in the case of Respironics, Flex. They are comfort features and you don't have to use either one if you don't want to.
Hang in there for more answers to your questions and much success to you with your CPAP therapy.
