New CPAP User ready to quit - Central Apnea, ASV

FWIW: this is within OSCAR Daily charts view

Max PS is 12 because max IPAP is set to 16.

IPAP - EPAP = PS
16 (IPAP max) - 4 (EPAP min) = 12 (PS max)

You are having the odd obstructive apnea along with the hypopneas and these PR machines do not appear to react as quickly as Resmed. Higher EPAP is what is required to treat apneas and I would start by increasing EPAP slightly, this will also increase IPAP which will help with the hypopneas. I would set EPAP min to 6, IPAP max to 20, leave PS min at 4 (for now), PS max to 14 and try that for a few nights.

Can you swap out the pressure chart with mask pressure and post a couple 2 min zoomed in views of the hypopneas. Also curious to see one zoomed in normal breathing area. Kind of curious as to what is happening and how these PR machines respond.

This unit doesn’t show IPAP. What should settings be?

Max IPAP = max pressure.

[tntfrahm]

OK. Here are the settings now. Is this correct?

Pressure = 20
EPAP Max = 9
EPAP Min = 6
PS Max = 14
PS Min = 4
BPM =auto

Assuming pressure is max pressure yes that looks good.

Go to view-> reset graphs-> Advanced  This shift the charts to display the respiratory values that better suit an ASV.

We made this easy in the new version of OSCAR that you have

[tntfrahm]

OK. I reset the graphs to Advanced.  Also, took new screenshots after.  Also included zoom in on hypopnea and normal breathing.

Here are the rest of the screenshots.

I don't know what algorithm PR uses for their ASV's but it is obviously much less reactive/forceful than Resmed's (only supplying 4-6 cm PS even when hypopneas are occurring). Increasing min EPAP and min PS will make the biggest differences with this machine, lets stick with the current changes for now to see what they do.
