MY MOTHER HAS CPLD AND IS ON OXYGEN, THE PROBLEM IS, HER SINUSES GET LARGE HARD BLOCKAGES HIGH UP IN THE NASAL CAVITY. WE HAVE TRIED WARM WATER IN THE NOSE. NASAL SPRAYS. THE ONLY THING THAT HELPS HER IS SITTING IN THE SHOWER. SHE WILL BLOW HER NOSE FOR HOURS TRYING TO GET THE BLOCKAGE OUT. BY THIS TIME SHE IS TOTALLY OUT OF BREATH AND HER HEART IS BEATING QUITE FAST(SHE ALSO HAS A PACEMAKER). THESE BLOCKAGES ARE STOPPING HER FROM GETTING THE OXYGEN SHE DESPERATELY NEEDS.
