Hello and hope you are doing well.
The ear infection could be causing the nausea and dizziness. Do not discontinue CPAP therapy. The infection is not related to this therapy. If the present pressures are uncomfortable, you could try BiPAP, which is a bi level pressure device, which regulates according to inspiration and expiration, and hence is more comfortable. You will need to consult your primary care physician for further evaluation, who may then refer you to an ENT specialist. As the infection resolves, your symptoms should improve.
Hope this helped and do keep us posted.
18 seems a bit high, but I don't think it would be fatal. In my opinion you are a victim of ancient philosophy and outdated technology. They come up with a number as a result of the sleep study and you are stuck with that setting until you are tested again. This is so wrong. Your pressure requirement changes over time and through the night. An auto setting machine is like having a sleep study every time you put on the mask. It makes adjustments continuously as you sleep. You have the exact correct pressure all the time.
Hi. With regards to using your CPAP, when you have a diagnosis of sleep apnoea it is important to use the machine every night for a minimum of 4 hours. If you are not compliant with treatment you are at a high risk of cardiovascular issues and also at risk with driving and cover from the insurance company.
It would be important if you have problems or concerns that you contact your healthcare provider. It may be that you need your pressure re-assessed, it may be too high and this would cause the machine to be uncomfortable to use. Hope this helps.
