Supplemental Oxyge

Post by Carry On » Sat Nov 21, 2015 10:05 pm

The pulmonologist thought I should have supplemental oxygen with mild apnea because my SPO2 dropped below 88% about.5% of the time over 7 hours of sleep. The lowest 77 for 15 seconds. Average low is 89%. Average is 92 to 94 the rest of sleep time.

His seems an dubious recommendation at great inconvenience to me.


It can drop longer and lower in a plane or sleeping in mountain resort. Who is closer to the truth.

You are!

Many of us have even lower and longer desats when tested and otherwise, but vast majority is not on 02 for them... the whole point of Cpap is to treat OSA and accompanying desats, and most of the time it does, pretty well, so I have no idea where that doctor was coming from. Of course if, in future, you're found to still have serious problems, then things can be revisited and if you do need 02 then you'll need it, but I wouldn't just jump on that wagon now without more evidence that you have a problem when on Cpap. 88% is actually considered the borderline low fig. for problems, and 5% of the time there is no biggie at all.

In order for that to be realitive, you must first determine your XPAP treatment is maximized for the best results. After that is done, you check your O2 destats, and make a valid deturmation if you need O2, and how much vaule it will give you.

You need to use the software and data to make this judgement..... adding O2 is a big cost profit item, lots of modivation. Jim
Use data to optimize your xPAP treatment!

Carry On,
I have COPD as well as OSA. I'm on fulltime oxygen. It is quite an added expense, but in my case a necessity.

Do like the others have suggested and get your CPAP right first, then see if it shows a need for supplemental oxi. Fulltime oxygen is a real pain in the patoot.

Cheers,
otrpu

Because of the nature of XPAP, which utilizes air at a higher pressure, even those on oxygen typically need lower amounts in order to maintain saturation. I agree with the other posters, get your XPAP optimized first. Once it is working well and you are experiencing fewer events, then worry about the need for supplemental oxygen.

Thanks everyone. Appreciate the help. What is an XPAP? I am on ASAP, automode. Pressure about 4 to 7 most nights. A few times 10 when my nose is stuffed or some other cause. Bee measuring dental on CM 50. Average time below 88 is 15 minutes or less. Peak low of 75 for 15 seconds. Waiting for overnight study results but if the doctor takes a knee jerk reaction and wants O2 just for 15 second low, I will wanto know why? I don't know the study results but the tech said I was fine and I been measuring at home with the ASAP for six to nine hours with nothing appreciable below 88, mainly the numbers above which less that plane trip or vacation on ski resort.

Moreover too many variables such as sleep position, hose position and allergies and sinusitis which I have.

I hope a typo in my initial post did not confuse. The time less that 88% was 5 minutes over over seven hours or about 1.2%. As stated, no worse than a cabin on a mountain or a flight. Cannot appreciate the doctor's concern or motives.

Xpap = Cpap, Apap (autopap... no 'Asap'), Bipap (bilevel pap), etc, etc. (there are more).

It would help if you could post your equipment using text mode and the "User Control Panel" so everyone can see what actual machine you are using.

I believe that a total of 5 minutes or more desaturation below 88% is considered sufficient to prescribe supplemental O2 at night. A O2 level of 98% or so is considered normal for being awake and on room air. At night, that would drop some but not down below 90% for most people. Mine was hovering at 90% at night with a fully optimized CPAP but during airline travel, I had to hyperventilate almost continuously to keep it at that level. Hyperventilating for hours on end gets really old. Consequently, I don't fly any more. My pulmonologist prescribed O2 for me to try to get my night time SpO2 up above 92% and stay there.

So, if you are spending time in the mountains, you should expect to see more desaturations than at a lower level.
Average time below 88 is 15 minutes or less.
is a strong indicator of the need for O2 at night. It's not the 15 seconds at 77% that is the worry, its the total time below 88%.

JDS74 and I sound like twins based on his post. We both use the same machine and both use supplemental O2 at night. I use 3 litters per minute to keep my SPO2 above 93 with occasional brief dips below 90.
I guess I am more pro active than the other posters here. I have been on supplemental 02 since my PCP suggested I might have sleep apnea and scheduled a sleep test.

I'll add my name to the list as well. JDS and I went on supplemental O2 about the same time, using the same machines. My desats below 88% were around 176 minutes. The first night on O2, I felt 100% better. My doctor prescribed 2 liters, but I was still hovering around 90%, so I bumped it to 2 1/2 and am usually around 94% now. It has really improved my life.

Overnight sleep study did not confirm low O2 at any point but suggested after titration that CPAPshould be fixed at 12 Cflex+. Took a few days to adjust to higher pressure. AHI down from 7 to 3 now.
