That silicon seal is easy to remove and wash. As Sierra said, if the seal is not properly in place that could be your problem. Check the inlet and outlet inside of the machine to make sure that they are sealing properly.
I clean mine weekly. I use hydrogen-peroxide inside of the water reservoir and let it soak a while, rinse with tap water. The hose and face mask I wash with hand soap. That works for me. I found that it is critical to change the filter to avoid lung infections.
Expectations... I had a little different experience. I suffered with sleep apnea and didn't know what it was. I couldn't sleep, couldn't breath, was never rested. My friend had sleep apnea and slept with a BIPAP. I had never heard of it before. What he described to me about it sounded like it would help me. That was 2001. I went to the neurologist, had their sleep study, and finally got my CPAP in 2002! I was thrilled to get it. Since then I use it every night and don't even nap without it.
Was it magic? No, but it helped immeasurably. It didn't lower my blood pressure (I don't think) or help me loose weight. I had some hopes that it might, but never the expectations. But, it improved my life and health and I am very thankful for it.
And when we lost power and I had no CPAP, I struggled to sleep that night and it reinforced what the device did for me. And after a two hour drive to stay overnight, I turned around and drove home because I forgot my CPAP and wouldn't consider sleeping without it. I remember all too well what a struggle it was to sleep without it.
I try to learn from those who are further along life's journey than I am. I see their health struggles and know that my turn may come. That's part of the journey. You know the old saying that getting old is hard, but think of the alternative!
My wife and I both have Resmed S8 CPAPs. Our switch pads stopped working and we did the plugging and unplugging thing for a while. Recently we both wanted to reduce our air pressure and in order to do so we actually had to shut the machine off using the key pad so that we could get into the Clinical menu.
I searched and read a lot of forums and tried the cleaning with alcohol, sanding the contacts, etc. I finally ordered some conductive paint because... what did I have to loose.
I am here to tell you that it worked like a champ! For $13 I bought a small container of conductive paint. My wife applied it to the tips of the keys using a toothpick. It doesn't take much. They both work like a champ now. We are back to using the key pad to turn them on and off and get through the menus.
I actually joined this forum to let others know that this worked for me. It was a simple, effective, and inexpensive fix.
How to fix that S8 key pad that just stopped working.
