You will be dead long before the levels reach 0. After you are dead the oxygen in the now non circulating blood will have nowhere to go, so I would be surprised if the level ever reached 0.

I remember watching a documentary where a man who had climbed to the south col of mount Everest measured his O2 levels at 35%! He was still coherent and managed the extra 3000 or so meters of altitude to the summit with just his lung power. Heaven knows what they were at the summit.

Of course he was a highly fit athlete at sea level and spent a long time acclimating to the altitude before the summit push.

I'm sure if I'd seen 35% O2 levels in my PSG, I'd have a heart attack Smile Thanks for the info..

[attachment=2060] so here is last night with minimum pressure bumped to 12 and tape around the oximeter...not feeling as rested as the prior night but O2 levels look good.


Any idea what the gray bars (in flow rate graph) represent? I get them occasionally but some nights I get none. The manual refers to green bars in the flow rate graph, but not gray.

thank you !

The gray bars are major leaks. For a Resmed that is usually anything over 24 lpm.

One thing you can do is adjust the y-axis of the graphs. For instance the Pulse Rate graph starts from 45 and goes up to 245. The reason for that is that the y-axis is set the auto adjust by default and any misreadings due to the oximeter gives some unrealistic data like 245. If yo look closely to the graph you can see that the maximum pulse rate you get is below 95. So, you could easily override the default setting to show min 45 and max 95. This way you can have a clearer look on your readings. How you do this is by right clicking on the y-axis scale and changing the setting.

The same applies for the SpO2 and all other graphs as well.

This comment was intended to be tongue-in-cheek and point out the virtual impossibility of obtaining an "real" 0% SPO2, but way to call it out. Too-funny
