Respronics Dream Station Software Reading
#1
Greetings,

I am trying to understand on the Dream Station software basic Dream Mapper what Respironics considers to be an excessively high leak, which might affect my CPAP therapy results. Specifically my reading was mostly 100% successful leak rate but for the last 2 months, it has dropped to varied 90% success and usually around 97% compliance. I realize there are a multiplicity of reasons for a leak but I am pretty sure as my airflow increases to close to the max of 10.5 and movement of my head in the night, I have gotten use to the airflow noise and do not wake up constantly to adjust and as a result this less than 100% therapy is occurring. Should I be concerned about my therapy if the compliance is in the 90% and up? In other words is this considered an excessively high leak overall? I would appreciate your thoughts on this topic.
Thank you.

If you have a computer and download SleepyHead, the leaks are much easier to understand. Also, the EncoreBasic program will graph the leaks and other efficacy data. An excess leak in the Dreamstation is approximately 30 mL above baseline, or above 60 mL total flow. If you are hitting the large leak threshold 3% of the time, it's mostly disruptive, but you need to watch that the average leak stays low so your sleep is not so disrupted.

Resmed has recently released an Airfit F20 mask that may be better for your leaks. You might want to talk to your supplier about a replacement.
