Hi I'm new to this forum and after reading some of the posts I can see that the CPAP I'm using, a Resmed S8 Autoset Spirit II has become a bit out of date. It's the only machine I've ever owned since being diagnosed , I guess I've been using it for about 5 years and time has flown.
My question is - should I be thinking about renewing this equipment? I'm not having any problems with it that I'm aware of, other than I've discovered that the data retrieval accessories are a bit hard to come by. It's a lot of money to lay out for something that doesn't need to be replaced but I'm wondering what sort of life span I should be expecting from the machine and when and under what circumstances should it be replaced. Is anyone still using one of these, or have I become a CPAP dinosaur?
I think that if the machine isn't delivering consistent pressure or you're seeing a reduction in therapy effectiveness or are otherwise unhappy with your results then that constitutes a need for replacement. Unfortunately without data that's a hard thing to measure. Is your AHI consistently low? Have you seen a degradation in the machine's performance? There are ways to measure the machine's output with a manometer but I'm not familiar with the procedures. A subjective test is to ask yourself how you feel each morning.
Other than performance, the next reason to upgrade would be to get data monitoring capabilities which you may find beneficial unless you already have a very well controlled AHI. In any event, the data may be useful at a future time for spot checking, checking out new mask performance, etc. People's pressure needs are known to change over time and having the data is helpful.
Least important, in my opinion, are the features associated with a new machine. If you've already taken well to your current one and don't have a need for them, then it may not be worth the expense. However, your machine won't last forever and it's always good to have a spare. I don't know how long they typically last but I've heard of others using theirs for 8 years.
You might find that a newer machine is quieter. It's up to you whether that's worth the expense.
Thanks Paptillian, I think I need to have a look at the data like you said. I'm unsure of the machine's performance. I don't feel like I'm seeing as much benefit as I did in the beginning but that may be due to bad sleeping habits and not the machine's fault
