If you have been to the ResMed site and looked up there Adaptive Servo Ventilator (ASV) you would indeed find that this machine is a type of ventilator that is made specifically treat Central Apneas and Complex Sleep apnea, and Cheyne-Stokes breathing pattern, this machine has a computer in it that monitors and samples your breathing pattern and and then does whatever it takes to have your body maintain that breathing pattern through out the night. Most nights my average pressure is 12.2 but when I down load the data I find that many times during the night the pressure will go up way higher than that, to prevent me from having an apnea. It isn't unusually for it to go up to 20 or 25 or what ever for what ever length of time needed just to prevent you from having an apnea. A CPAP machine is not capable of doing that. Setting your pressure up high on a CPAP or BIPAP machine can indeed make Central Apneas worse in some people. CPAP and BiPAP machines are not the same as the ASV machine they are not ventilators. They do have special algorithms that they use to control the servo motors that run their machine and they are not about to release that information to anybody! Have you had a in lab sleep study done? and have you been told you have central apneas? That is the only way to tell if you are actually having central apneas, and the only way to get the ASV machine is to have an ASV titration study done, and have the script for it.
To put it simply these machines are a type of ventilator, and even if your brain is not telling you to breath, a ventilator can make you breath, just like when you do emergency CPR on a person, you breath into a persons mouth or nose and fill the persons lungs with air, and when the person stops blowing air into the persons lungs the lungs contract ( natural position) and the air and carbon dioxide comes out, and then the person blows air back in and fills the persons lungs, well a ventilator does the same thing, but allot better, and these ASV machines are very sensitive and monitor your breathing and give you just the right amount of air that it senses, that you need. All I can say is that it works! Read up on the machines and read up on human anatomy it all makes sense! I hope this has helped you! I do wish you luck! You are right about SSI tjhey not going to pay for one of these machines, unless it is proven that this machine is needed! These machines are very expensive! But if your having central apneas they are worth there weight in gold! I started off on CPAP and then CPAP with supplemental, Oxygen and then BiPAP with O2, in a year in a half I had 5 in lab sleep studies done, and every time they increased my pressure and all I it doing is making me worse! Well finally my sleep doctor got sick and I had to see differnt sleep doctor, I then found out that the sleep center had been recommending that I be put on the ASV machine from the very begining, but ,my old sleep doctor did not believe in the ASV machines he thought the techonology was to new and not proven, so he just kept raising the pressure and I just kept getting worse, because my central apneas kept increasing. Soon after I had my sixth sleep study, an it was an ASV titration study and I was put on the ASV machine, my night sweats disappeared and the nocturia stopped and in about 90 days the extreme fatigue and unrelenting tiredness finally was lessening its grip on me, and with in a couple of more months it was gone!
I wish you well and Good Luck to you White Beard
???? What is so painful about putting air into a persons lungs? If a person is being intubated that could be uncomfortable and painful, but just putting a mask on a person face and increasing air pressure. ??????
