Thanks for all the comments folks.

That 22 cm spike doesn't make any sense to me. 1) The machine can't go above 20 cm and 2) I set the maximum pressure to 14 cm. What's up with that? I don't get it. Can/will anyone explain that? I don't know how the Z2 reports pressure or what exact terminology the reports use, but there are two pre...

I'm surprised you ask. It's just a random error in the data. I agree its an error - thats why I asked abo...

Yes Nitelog is terrible. However you can glean some basic info from it, enough to accomplish your goal. If the pressure is staying down near 8cm then you will certainly get more run time from your power banks. How did you feel with an ahi over 5? As you realized, you probably don't want to set the ...

Even though I don't have time to experiment with the battery I decided that I could experiment with the machine since I've never used APAP. I downloaded the NiteLog software set it up and then changed the settings on my Breas Z2 to APAP with a minimum of 8 and a maximum of 14 cm. My normal settings ...

I’ll toss in a data point which may or may not be useful. I used my Z2 this past weekend for one night using the HDM/Breas battery (which is rated 99Wh). My settings were APAP, min 12cm, Z-breath 3. I slept for 8+hrs with a 95% pressure of 13. Two bars remained on the battery in the morning meaning...

To answer your question specifically, what you are asking is not possible. You cannot directly compare cpap to apap mode at 14cm. In apap mode the Z2 requires that you select a pressure range of 1/2cm or greater between the high and low settings. Your settings and what pressure the machine decides ...

when I pushed him he prescribed 14 cm with a 13 cm lower limit (big help right?). You know you can easily change those settings? Instructions for your machine on youtube. Thanks. I have the clinician's manual and know how to change the settings. So, that is not an issue Currently, I'm intentionally...

Asking what mode CPAP or APAP uses more energy, doesn't really make sense. What ever mode spins the blower more will use more power. And that is dependent on what the specific APAP settings are and where the device is all night. Given the Z2 isn't supported by OSCAR there is no way to tell. On syst...

A bit on power banks. If your lucky the seller will list the watt hours. Watt Hours is what you want to figure out, that is the most relevant rating when looking at battery capacity. Watt hours will be relatively the same no matter what voltage you choose to run it at which can be widely different ...

30,000 mah battery Amp Hours is a pretty useless measure unless one knows the voltage that the number is based on. Is that 30,000 mah at 5V? 12V? 24V? Big differences there. Do yourself a favor and do like that poster does in that other thread - use Watt Hours for everything. And don't buy any batt...

I'm a backpacker and I'm going on an overnight next weekend. I run my z2 in cpap mode and my prescribed pressure is 14 cm. maybe you can find an answer here- https://www.cpaptalk.com/viewtopic/t179963/Battery-solution-for-Breas-Z2-Auto-and-HDM-Z1-CPAP-offgrid-backpacking-camping-usage.html good luc...

I'm a backpacker and I'm going on an overnight next weekend. I run my z2 in cpap mode and my prescribed pressure is 14 cm. I don't have time to experiment with a lower pressure setting before next weekend so I need to get the most from whatever battery I buy. I did some measuring for a week and my z...

I sent a PM to someone as a follow up to a topic I'm interested in and it went into an outbox and never sent. Why is that? it's how the forum software works. it stays in the outbox until the recipient logs in and reads it. Great, thanks! I belong to at least a half dozen other forums. None of the o...
