It depends on model, the portable oxygen concentrator can be pretty quiet. I've looked at some in the past, as I thought one was in my future. Not yet, just like all other therapy devices right now. They're waiting till I get worse I suppose.
I think the brand I was drawn to was Inogen. It would in part depend on delivery mode, pulse or continuous, and L/min delivery value supplemental oxygen they're after.

KC90, I wrote the Oxygen Bleed wiki, so if it's confusing to you, it would help to hear your questions so I can make it more suitable to lay-person understanding. It's not an easy subject. I think we an rule out altitude in MO. Oxygen is an easy fix because increasing the oxygen concentration breathed in will normally cause SpO2 to rise, but it's also important to dig into why a V/Q mismatch is happening.

Hi Sleeprider, your wiki is good and well-explained. I more meant the confusing part is not having any COPD/Heart failure or living at altitude and still having low SpO2 when me AHI is never more than 1. Im just confused as to what could be causing this because I didn't even know it was a thing 24 hours ago, again I appreciate your response and your wiki.

I have multiple concentrators.
At home I use a phillips everflo that stays in another room at the end of a 50ft hose. It is a bit loud to sleep with and puts out a lot of heat. It puts out up to 5L/min
When we travel I use a phillips simplygo that is relatively quiet and it puts out 2L/min continuously. It is about as loud as an aquarium pump.
With an apnea machine you need a contiuous output verse the pulse output. All of the smaller pulse output machines don't have enough pressure to overcome the air pressure in the hose. The simplygo weighs 10lbs and is about the size of a playmate cooler. The little inogen g5 my wife uses weighs 4lbs and is 1/3rd the size.
The stationary units need servicing after 5 years or so, and the portables are good for 3 years. The service means new filter columns and a compressor rebuild if it is running loud.
Note: you can buy a new buy a new stationary unit for only a few months rental from a DME. Typically a DME won't provide a portable unless you need it 24x7x365. With a new unit and a 3 to 5 year warranty there is no worry about service.
We started monitoring O2 a year before either of us was diagnosed with apnea. When covid came around we brought my mother to live with us and had to monitor her SpO2 closely and bought a concentrator for her. Well of course I check my self and my wife and then we got the first O2ring.
Sleeprider: thx, I'll try the settings tonight. I have been fiddling with them recently and anytime I exceed a pressure of 14 my chest hurts the next day. I was able to eliminate the events with 6.8-9, 0-7 but it made me feel like I have a chest cold.

Found it

Sleeprider - here are the graphs with the changes you suggested - I'll keep with your settings a few more days and see how it feels.
With the settings 6-8, 0-6 my graphs are clear with no events - AHI between 0.0 and 0.62 - I was fiddling because I was swallowing air.
The original titration test said use ASV mode and 9, 0-5... That is where the zero came from.

Looks a lot better. Just a brief positional episode at 03:20. My hope is that using a higher minimum PS you have better comfort and more consistency. You are showing a bit higher tidal volume with this change. The lowest SpO2 between 04:20 and 05:00 is not associated with any events or drop in minute vent or tidal volume.

Yep looks better. Going rogue is the way to go. I found ASV Auto better than ASV mode.

I can't get used to the higher pressure so I tweaked it a bit down. Was restless and tossed a good part of the night but here is the graph. I also posted my graph from 12/24 - only my second 0.0 ahi since I started.
KC90 - sorry I seem to have hijacked your thread - back to you and I will switch to my own treatment thread after this.
