here goes my tangent....
This isnt like driving a car or using insulin. Insulin has a pretty easy sliding scale to follow...if blood sugar is x, take x amount of insulin...piece of cake. You cant take a read out and apply the same principle.
You dont know what is causing you to wake with ringing in your head so thus, how do you expect to fix it? You have to know a problem in order to properly come up with a solution. Changes to your CPAP pressure can cause a cascade of different reactions. Not only do you not understand PAP you also dont understand gas laws. ambient air has a lot of oxygen in it, 21% of it is oxygen. Your body does not even absorb all 21% from the air you inhale which is why mouth to mouth resuscitation is even possible. When you inhale, your body only absorbs 5% of the available oxygen and exhales the remaining 14-16%.....and that is someone with normal lungs and no obstructions.
You want my recommendation? Leave the interpretation to those in the know or go to school to learn how to do it properly. This isnt a DIY project. The changes you make to the machine can have very real consequences. The data from the machine is not going to give you the additional information you need to make a good, informed decision on if you need to make a change and how much. Data from the machine is not going to give you heart rate, oxygen saturation, or EEG readings.
My recommendation is talk to your physician and have them right an order for autotitration, have the DME set it and leave it alone. It will self-titrate fairly closely to what your body needs. You do not have the education to do this on your own, and you arent going to learn it from the internet. It may not feel comfortable at first but over time your body should get used to it.
Some additional concerns about wrong pressure settings...too high can also cause increased intrathoracic pressure which can impede venous blood return to your heart, impeded venous return can cause increased intracranial pressure...and also increased blood pressure...and what bad things can hypertension cause? Im just trying to impress upon you that "change A does not always give result B"....you can also cause gastric distention...think of your worse case of gas x100 and being unable to burp. Someone mentioned blebs...do you know what a bleb is? blebs can lead to a spontaneous pneumothorax...ie collapsed lung....I've seen it happen right in front of my own eyes...patient with bad blebs coughs real hard...after a little bit their lips turned blue, they also become hardly responsive, code team arrives, and luckily, for that patient, they lived....and this was in a hospital! (that bleb wasnt from PAP).
I use an APAP (m-series) so I'm able to talk from both sides of the mask. I dont know how they do it in Oz but no good doctor in the US would advise their patients to change their settings themselves, not because of control or cash flow, because of the harm it can cause (and risks of being sued). being comfortable enough for you to sleep 4-7 hours may be too little pressure..."being able to sleep" doesnt mean you are getting enough of the right kind of sleep, only an EEG would be able to determine your sleep efficiency at a given pressure.
Really you should drop the "IM ENTITLED!" attitude and leave it to those in the know. Im all for someone being in charge of their healthcare but not for recklessness because they think they can do it better themselves
Sorry Mrs Rip, if you dont want any further posts from others I would recommend locking the thread
