Summer Canada 500 feet alt.
Winter Mexico 5000 feet alt
I switched to an ASV 12 days ago. AHI 0.2. Last two days were 0. It has been a year of frustration but now feel great! Appreciate all the help I received!
Many thanks bonjour. First night AHI is O.1. It will be interesting to see what happens when I move from 500 feet altitude to 5000 feet in October.
Thanks bonjour. They have admitted that they have screwed up. Scary stuff. I am scheduled to pick up an asv tomorrow but i am concerned about their competence in setting the machine up correctly.
I cant believe I am asking this question. I picked up a resmed asv loaner, device number 662 on Friday. I used it once and entered the results in sleepy head. It is showing centrals. I thought the machine eliminated centrals completly. Also the machine didnt feel any different than my current aircurve 10 vauto.
I looked at the front of the machine and it says aircurve 10 vauto. I looked on the resmed site and their asv has asv on the front. The lady at the outlet thinks its an asv. What gives??
Where can I get the best price in Canada for an asv machine? There are cheap prices in the USA but my understanding is that either the government or the manufacturers make it difficult to import one.
On May 3rd my sleep doc changed my settings to ps4 over 5.0-14.0 and changed them slowly to the current ps4.0 over 5.0-11.0. My ahi has gone down slowly. Median minute vent has gone from 5.88 in early May to 6.25 recently.
The last year has been a struggle bonjour. In May 2018 I felt awful -tired, not sleeping well, needing afternoon naps. My Doctor of 30 years could not find anything wrong so I got a new Doctor who referred me immediately to a neurologist/ sleepDoctor who immediately set up a sleep study in mid July 2018. Got the results in mid September - Ahi of 67 made up principally of hypopneas and to a lesser extent obstructives ( I used to sleep on my back). I had no centrals. Then he put me on a cpap machine. A second sleep study recommended a pressure of 20. Had trouble keeping my mask on. I switched to a Resmed 10 curve v auto. I then went to Mexico where I winter at 5000 feet until April 15, then back to Toronto - 500 feet.I found that the high altitude increased my Ahi significantly and my readings were in the high twenties, and mainly centrals. I used acetazolamide which brought my AHI down to the mid teens. My sleep docs strategy is to get my centrals under 5 at 500 feet in the summer and then use acet in the winter at 5000feet. Currently my AHI is around 8 with almost all centrals and one or two obstuctives and the odd hypopnea. We are slowly reducing pressure . He has also suggested a mouth piece which I have refused. The last thing I need right now is screwing around with my teeth/mouth. I have suggested an ASV machine but he is reluctant, but will agree if I push him.
My take right now with my one year of experience is that I have Treatment- Emergent Central Sleep Apnea whereby the centrals are being caused by my sleep apnea machines and the most effective treatment is via an asv machine. I also expect that I will need different settings at 5000 feet, perhaps including acet.
I feel a lot better than I did at 5000 feet but i still get brain fog and am tired. I need an afternoon snooze around 2 hours and sleep around 8 hours a day. My memory Has become worse
I live in Canada, my province does not cover asv machine so I have to pay the total cost. Based on the US model, I would qualify. I wake up several times a night but I do not have shortness of breath. It usually happens when I have obstructives or a bunch of centrals. When the wind starts blowing, my wife can tell that I am having an obstructive.
Thanks for your response Sierra. You may recall that I spend the winter at 5500 feet and 6 months at 500 feet where my sleep doc is and I am seeing him once a month. My current settings are ps 4, 4.0-11.0 and my ahi is dropping- last night it was 6.5 My winter ahi was around 15 plus as I have trouble with altitude. He prescribed acet. which brought my winter afi down to around 8. His plan is to continue to slowly reduce pressure till we hit the sweet spot while at 500 feet and use acet.at 5500 feet. After 10 months I am getting tired of this process. I have suggested an asv but he prefers the current process. My current thinking is to ask for a 30 day asv trial when I see him next week which I think he will agree to.
I have been treated for sleep apnea for 10 months . I started with an ahi above 40- mostly centrals and now are down to 8,mostly all centrals with the odd obstructive and hypopnia. Iam currently using an aircurve 10vauto. I seem to be stalled at this level.
My question is - will an ASV machine eliminate my centrals? I do not have heart problems. I would appreciate hearing from current ASV users who have gone through the process. What are the pros and cons, if any.
It worked. Many thanks.
