hey guys, could you tell me if my machine seems like its responding to events or if its just the normal pulsing of the machine?

ResMeds don't "normally pulse". Your machine is responding to "events". If you look at the top graph, focus on the clusters of Flow Limitations, than move upwards you will see an increase in pressure. This is your machine responding.

You might consider increasing your minimum pressure to 8 and see if you could flatten that line a bit and clean up your Flow Limitations.

oh wow. thanks, i am used to the phillips pulsing i guess. not sure if all phillips pulse or if it was just my machine

if my pressure wants to go up to 12 to save me from apneas, what is the logic in having my starting pressure lower than 12?

Because we have different pressure needs from night-to-night and during the night.

i.e. When on one's side during non-REM sleep 10cm of pressure may be all it takes to address ones apneas. 30 minutes later, on one's back, during REM, 16cm of pressure might be required. One shouldn't need to constantly receive 16cm pressure all night when it's only required for part of the night.

This is exactly the role of Auto-adjusting (APAP) machines.

but then youre subjecting yourself to apneas that could have otherwise been prevented. do people just not want higher pressures because they think it disturbs their sleep?

Not necessarily. Your minimum pressure doesn't have to be obscenely low. It should be sufficiently high so as to get to the required pressure. The machine does not auto-adjust based solely on apneas. It will start to increase pressure when it senses key indicators such as Snores and Flow Limitations.

Higher pressures can be uncomfortable for some, contribute to mask leaking, cause aerophagia.

Your pressure range is set to 7-12, some require pressures beyond 20.

But be my guest, move your machine from 7-12 to straight CPAP at 12. There's a reason the industry is moving from CPAP to APAP.

but snores and flow limitations in themselves disturb sleep, no? and theyre basically fractions of an apnea. also, is it possible that the machine i have is just picking up on sjw from the graphs i posted?

I guess they could, it's a matter of degree. They simply are NOT the problem hypopnea and apneas are. The machine senses them, treats them, and potentially prevents Hypopnea's and Apneas.

and theyre basically fractions of an apnea.

"basically fraction of an apnea", uh ok.

But, let's go with it. If they are a fraction of an apnea, they can be treated with a fraction of the pressure require for an apnea. This reinforces the preference of APAP over CPAP.

also, is it possible that the machine i have is just picking up on sjw from the graphs i posted?

No, we clearly see your machine detecting, measuring, responding and treating Flow Limitations all night. SWJ doesn't occur all night.

well i wake up throughout the night though

why would less pressure be needed for a snore over a hypopnea or apnea? unless its a positional/gravitation difference it seems like the same amount of pressure would be needed because its the same tongue blocking the same airway

Are you asking honest questions? Or, do you think you are going to come along with no experience/no education in sleep apnea/CPAP and overturn 40 years of research and development by educated and experienced medical researchers?

im asking questions i genuinely want answered
whats wrong with the ones ive asked?
swj is a legitimate term used on this forum and ive seen it used frequently
i recently switched machines and im wondering if this machine could possibly be detecting swj
also, it seems like in terms of health,
keeping ones pressure at the level that would prevent every bit of snoring/closed airway,
is the best way to go
unless the higher pressures disturb sleep more
im not asking to be a contrarian
just asking because im curious to know what the best chance of me
sleeping well is and why since i have sleep apnea i like to try to do
whats in my power to achieve as good of sleep as possible

Just to add, I got a sleep apnea test 5 years ago with a home kit, said I did not have it. Symptoms remained for years and eventually got an in lab test and I had mild sleep apnea. Can't be certain I did not have it then but the symptoms back then were the same as it was when I was diagnosed years later. I felt like I got very little sleep that night but they said they had enough data.

do the flow limitations absolutely confirm that the events are real? and i see there really arent any snores
would the snore line show up if the machine were turned down lower?
also, why wouldnt the snore graph match up with the flow limitation graph?

any help?
