I see that much on this site is on apnea, the ailment. However, my issue today is replacing an old ResMed device. I have researched and found a replacement on the ResMed site, but seem to be unable to kick through the bureaucratic obstacles on the part of local suppliers. I would like to hear from others about obtaining the products needed. I have Medicare, and know their requirements are many, but is their aim to make me go bare, gasping for breath? Please help, or refer me to a person or website with good information. ABBY
