My father have to use BiPAP machine (Resmed VPAP III ST) 24 hours now. I am worrying about how reliable the machine is. Do I need to buy a backup BiPAP for him? The first was covered by insurance. I think we have to pay out of our own pocket for the backup. Could anyone tell me where I can buy a good priced new or used BiPAP ST? It is very hard to find a ST model on line. Thanks!
