From Resmed Airsense S-10 Clinical Manual: "Ramp Time
Designed to make the beginning of therapy more comfortable, Ramp Time is the period during which the pressure increases from a low start pressure to the prescribed treatment pressure. You can set your Ramp Time to Off, 5 to 45 minutes or Auto. When Ramp Time is set to Auto, the device will detect when you have fallen asleep and then automatically rise to the prescribed treatment pressure."
"AutoSet mode
The treatment pressure required by the patient may vary due to changes in sleep state, body position and airway resistance. In AutoSet mode, the device provides only that amount of pressure required to maintain upper airway patency. The device analyzes the state of the patient’s upper airway on a breath-by-breath basis and delivers pressure within the allowed range according to the degree of obstruction. The AutoSet algorithm adjusts treatment pressure as a function of three parameters: inspiratory flow limitation, snore, and apnea."
The issue is for people who need high pressure. Yes you can set it for 7cm but when it "detects you have fallen asleep and then automatically rises to the prescribed treatment pressure" of say 13 or 14cm it wakes up us light sleepers. I find I do much better using the AutoSet mode. But YMMV.
The problem with the ramp for a lot of us, especially light sleepers, is that we fall asleep with the lower pressure and then when the high pressure kicks in it wakes us up. The Autoset feature slowly increases the pressure as needed so it is not so bad. But when the Ramp is turned on for a certain amount of time it can be very jarring when the pressure suddenly increases.
You and I sound a lot alike. First thing I do when I get a new CPAP is to find the manual for the clinical settings. It amazes me that doctors often prescribe the Ramp turned on, the EPR turned off, and set the PSI for a specific number or a very narrow range. All I can figure is that they don’t use CPAPs. (BTW, I am also 69. Enjoy the last year of being able to say, “I am in my 60s.”)
Thanks Regina. Amazingly, I think I have gotten the rainout issue under control. Some combination of the things I tried finally worked. (See below) The only reason I like the Airsense 11 is that I like the "For Her" auto setting for the pressure. The machine adjusts the pressure as needed. It starts at 4psi and can go up to 20, though my highest psi needs seem to be around 13.5psi.
My current set up is that I purchased a hose cover, keep most of the hose under the cover at night, and then I played around with the settings. For me, a humidity setting of 4 and the temp somewhere around 76 seems to work. (I am going from memory with the temp since my machine is not here.) The one very small problem is that sometimes in early morning water will drip our of the right angle hose connecter, but I can live with that!
Though I appreciate your willingness to write a long reply, I specifically asked people with AirSense 10 to please NOT REPLY because this is a AirSense 11 problem. I used the 10 for over seven years with no problem.
The issue with A10 people replying is that your info does not help, but it makes it very difficult for readers in the future to scroll through answers to find information that actually relates to their machine. There is a post from two years ago on this same issue and it is filled with A10 users trying to help. But there is no resolution for A11 users. That is why I posted again.
Sierra, I know you are trying to be helpful, however, I just looked back and you were the person who hijacked the post from two years ago too. Please stop doing that.
This issue is specific to ResMed AirSense S-11. Please do not reply about older AirSense models. They do not have this problem.
13 year CPAP user. I used a Resmed S-9 for 6 years, and S-10 for 7 years. Never have had any rainout of humidity / tubing issues. Just switched to an S-11 and have had nothing but problems.
I have been getting horrible rainout problems. Here are the things I have tried (multiple times)
The tubing never feels warm. With my S-9 and S-10, I could feel the tubing warm up. The water tank level does decrease (but I think the water mostly ends up in the tubing).
I saw a post on here from two years ago, but saw no solution for a S-11. Lot’s of people replied with their experience using a S-10. But I have never had problems like this with an S-10. This seems specific to the S-11. There was no solution for the S-11 on the other post. Just replies about similar issues.
