I have not left any part of my CPAP/APAP at home yet...but I dread the day I goof and forget something vital.
Have not yet run into an issue with a too loose connection; but I will be watching for it now.
Diagnosed: 44 AHI when supine, O2 down to 82%
Treated since 20 Sept 2014:: 0.7 AHI, Settings 7-15, EPR on Full Time at Level 3
Better living through CPAP/APAP machines!
