ResMed Air Sense if set to no ramp but EPR ramp only ? new user posting 1 week oscar

[REMmi]

so, I'm trying to get TO sleep, is the reason the mask is on ; what else am I to do in that situation?

sorry, I still don't understand why the machine showed few positional issues when it was at the original settings then?   Since I'm new (but worked healthcare myself), I do best with explanations , so ;


1 wondering if the 1 year of low AHIs were misleading?  and hence, the original 8-20 default was fine?

or perhaps, though it said AHI 1.0 , the latest AHI is truer to the situation then? I don't know that I had positional static on the original settings ? Esp. since there were so few events listed



maybe one night's tracing , which is part of the problem, where poor sleep = poor tracing ; isn't enough ; I know the guide say do no more than 0.5 pressure changes and let them work for a while?

fwiw, I felt the initial sleep was quite good, maybe 4 hours ; but the machine said SD card error , which happens quite often ; so didn't post that tracing.

Without prior data, unfortunately we'd only be making guesses.

Were you using OSCAR charts at that time, or was it another report tool? Example MyAir app which is notorious for just being a CPAP cheerleader with little useful info.

This Positional Apnea may have existed prior as well, however you might not have seen it or recognized it. Maybe the mask was leaking a lot, which means therapy is far from ideal.

yes, oldest tracings with Oscar I have are with the 6-11 prescribed Rx settings from Dec 11th, during which the AHI was 1.76 over 8 hours ; what I seem to notice is that for 6 hours there is almost no events, then strong clusters of RERA, so for the 8 hours the RERA was 1.88 ; if the AHI was measured for the final 2.5 hours the AHI must be very high.

So, positional issues at the end of the night consistently, does that makes sense?  ; the F20s airfit sidesleeping, at the end of night, I recall being frustrated trying to get it to stop burping around the cheeks, and numerous times, just deciding that's it for the night, and getting out of bed for the early morning .

That said Oscar imported all the Myair data July 1-Dec 18=, just no tracings, median usage 6.3 hours, AHI 1.24 AHI median 0.80 ; 95% flow limitation 0.14 ; avg leak 2.5 average pressure 9.1 ; min 6 max 14 95% pressure 8.46; min EPAP 4 max 14.0


am going to try again to get some coaching from my sleep dept,  once, I can get to a point where I feel I can ask informed questions, so do appreciate you folks,  cheers

It is not a settings issue at all. You are still having lots of Positional Apnea.

The aspect of EPR set to Ramp only with no Ramp will always equal the same as EPR is off. Don't do this.

If you were awake, despite the mask and CPAP being on, this counts as no therapy. A CPAP is sleep therapy only.

Hello, so last night, I was unable to get any solid sleep. Usually I get an initial 2-4 hours , the latter if lucky , then rest of the night is many many arousals, I assume I then drift back to sleep, but can't always tell.
However, when I look at My Air it says AHI of 6, and 100% ; I assume that is just because the length of time the mask was on my face?
Or can the ResMed Airsense 11 tell when I'm sleeping and does it just use the actual sleep time to compute an AHI.

I'm still waiting on a chinstrap and neckbrace, but am a bit scared to play around with the pressures, and EPAP. Though, after such a poor sleep I want to which a few small things back and forth,

I have received a paper copy of my overnight sleep study, the tech had me down to 0 AHIs ; though it was a terrible sleep. So I'm using that pressure of 6-11 tonight again, think I had it on 6-12 last night ; EPR of 1 only, also what I think they used at sleep study.

I noticed on my back , hands on chest , couple times my hands went numb, never noticed that before.

I have the SD card in the machine, and can post a redacted sleep study ? or just wait till neck brace and chin strap arrive in 10 days or so ?

seems like forever, trying to get the sleep any better, when one never awakes feeling normal for a few years , and the Cpap seems to have little effect

thankyou.

Don't worry about editing you settings. You can't harm yourself beyond possibly making sleep no worse than you've gotten now.

You want to find a way to screenshot your sleep study into info a post. It sounds like a split study, part without machine to give a baseline, part as a Titration to supposedly find good pressures.

The ResMed machine uses air flow patterns to compute waking or sleeping.

If you have OSCAR data this helps us with suggestions. As is common with many, your CPAP settings can easily be made better.

thanks dave,
I'm just interested to know if MyAir AHI number for the night is based on just have the mask on for an average over time  or is it based on time actually asleep?

As I am in and out of sleep the entire night, hence leaving the FFM on , also having some issue gauging how I feel in the morning, sometimes I think I feel OK, but really am not, I'm hoping to find some stability , I I had the overnight study in the hopes of getting somewhere , as the low AHI on 8-20 for 1 year, really didn't change how I felt , despite the very low AHIs , etc.

I know another admin here said move the 6-11 (sleep study, MD telemetry set) to 7-11 , and the EPR to "full, and 3" , however, reading a little about EPR,  re: the lankyleft RT, I got a bit concerned, so it's back on full time, and 1; I believe all last year it was set to "ramp only" , and I think "1" ; and I think the sleep study says "1" was used, when the AHIs were titrated to 0 the whole night, despite being all wired up and using an  under nose FFM that was uncomfortable.

So, one might wonder how metrics are going to correlate with "good refreshing" sleep sometimes.

I'll take some photos of the sleep study and post it here, if you agree, I'll just wait till I get the better chinstrap, and neck brace before posting more Oscar Scans?

I've never used a chinstrap but 1 night. atm, i'm going back and forth between standard and slimline hoses, AirFit and Airtouch F20 FFMs, seems the AirTouch memory foam prevents the late night side burping , that has cause many a night , to end early and bad :

take care

It's your choice on when to post the info. We're here to help, but not demand.

had a new experience, twice I awoke laying on my back, and my hands were numb. I'm trying to avoid making things any worse, and changing the settings too much, don't think I ever had the EPR to full time, until it was suggested in this thread, for example, based on one Oscar Scan I posted. Tonight, think I'm going to take something so I can finally get some solid sleep after the most recent runs of 3 days, start to get too tired to make decisions

well, my intention, right now, is to use no ramp, but also to leave EPR off, but I'm just guessing based on AHI results, I got the better chin strap, but I'm using a FFM, I guess, I should try the chin strap with the FFM ?

Sorry, I don't really understand what you mean by "don't do this" ; Are you suggesting while I'm trying to go to sleep , or get back to sleep in the middle of the night to remove my mask? Cause there is going to be no way, to know just when I will sleep or not, esp when I wake up 15 times after midnight , sigh

PS: my orginal question today, is simply how is the AHI calculated, is it per time with mask on ? or does the machine determine if one is sleeping and use sleeping time/ total AHIs to come up with a number?

also if "EPAP - (Expiratory Positive Airway Pressure) - The pressure prescribed for the expiratory (breathing out) phase of an individual on Bi-level CPAP therapy for OSA (obstructive sleep apnea). "
but, I'm not on a BiPAP machine I'm on Auto-CPAP? , should EPR be being used ?
and/or if EPR is full time and 3 what does that mean, that if someone is on 6-11 pressures, does expiratory pressure go down to 8 ? and how to look at an Oscar graph to decide that?

[SarcasticDave94]

You would get better therapy with EPR 3 full time with minimum pressure at least at 7. This will give you therapy much like a bilevel with a PS of 3.

If you take your CPAP set to min 7 EPR 3 or a bilevel with Min pressure 4 with PS 3 you'll get similar therapy.

The don't do this phrase meant if you try to mix EPR 3 Ramp only with No Ramp settings, this equals No EPR at all.
