Great Machine, LOVE this humidifier!

I used another manufacturer’s Auto-titrating BiPAP for years to treat my complex apnea (both obstructive and central apnea). I had failed CPAP testing in the hospital sleep lab because I was unable to exhale against sufficient pressure to minimize my obstructive apneas, so we went to the auto-titrating BiPAP to resolve my apneas, and my min EP and max IP pressures were determined. Synchronization combined with auto-titration seemed to resolve my central apneas by forcing progressively harder puffs of air — the only drawback was in this process the machine would often “run away” and go all the way to the machines max pressure of 25 and stay there. As a result, I would wake with the mask blasting air everywhere and I not able to breathe against it. The only resolution was to turn the machine off and back on. I purchased the Sandman Duo ST machine because of the very small and light size of the machine, the description of the “adaptive algorithm” in the machine, and the synchronization feature. It would be much more convenient for travel, and seemed it would possibly resolve issues I had with my previous machine. First, this is NOT an auto-titrating machine, as I had believed from the description of the “adaptive algorithm. Thus, because my pressures were determined as min/max auto-titration, the settings in the Sandman when I received it were way off. Fixed EP/IP pressures were not determined during my sleep study. I could not breathe with these settings, and short of a new hospital sleep study, trial and error were necessary to find pressures that promote good sleep. Are they the “correct” pressures? Neither my doctor nor I can really tell given the limited data the software provides. That said, with this machine I am sleeping very well. I turn frequently during the night and my respiratory rate changes significantly with position and other factors. Though breathing is fully synchronized by the machine, the sensitivity is such that the second I “exhale against the inflow,” the machine switches to exhalation and resynchronizes. My partner reports that I do not snore and, more important, don’t seem to have uncorrected central apnea episodes. Bottom line is that once the pressures and other settings were determined, this very compact machine really does the job. Another real plus is that I have always had to use the humidifiers on previous machines only in pass-over mode. Even on a heat setting of 1, I experienced drown-out. With this machine, I am able to set humidification level where I need it, currently at 4, and experience no drown-out. The humidity sensor really works. Going from an auto-titrating machine with only min/max titrated pressures to a fixed-pressure BiPAP was quite difficult, and gave a bad first impression of the Sandman. Had I had a prescription with correct pressures for this type of BiPAP in the beginning, I would have immediately known this machine is a champion. With correct settings now in the Sandman, I have given up all thoughts of going back to my auto-titrating machine.

Received my Sandman Duo ST BiLevel CPAP Machine a few days ago. It was easy to setup and operate. The machine operates perfectly giving me a restful sleep for the first time in many years. I live overseas and the machine arrived 6-days after ordering. I was able to track the progress of the shipment via UPS and was able to call UPS for a last minute change of delivery as it was arriving on the weekend when my office was closed. It was rerouted to my home so I could use it immediately. Thanks all for the speedy order and delivery.
