Trouble adapting to ResMed AirCurve 10 ASV

[JanetW]

I was on a Cpap for a year and my numbers were not getting better. In fact, my central apnea was getting worse. So I had a tritation study at the sleep institute and found that I needed the ASV Machine.  I received my machine this week and the first night was okay but the next three nights were very uncomfortable. I wasn’t expecting the air to push so hard and gets worse around 3:00 am. Last night my events were 10.4. I have two questions - how do I find out what my central apneas were versus the obstructive? I don’t see it in the back office anywhere.  Also, does the forced air get easier with time? I dread going to bed!

Thanks,
Janet

We use data to give suggestions on treatment.  You need to download OSCAR from the top of the site.  you ;need a sd card they are inexpensive to have in the machine while you sleep to get the info. from the sd card to the computer.  please post a nights charrts.

Should I purchase a specific brand or size SD card to be compatible with my machine?

Thanks

For the Resmed 10 series, you are limited to an SD card size of 2GB to 32GB. Any brand will do.

I suggest requesting your sleep study detailed report, and titration if done. Post redacted version. Include Oscar data if possible. And access the clinical menu to find your settings. There's mode then either a single EPAP pressure if on ASV, 2 EPAP pressures on ASV Auto, 2 PS pressures. IPAP is hiding in the algorithm, is not manually set, and is the sum of EPAP and PS.

Clinical menu access if you need it: Click and hold both Home button and the Dial together for about 5 seconds.

Once we find at least the basics, we can help you tune your ASV to work better quickly.

Here is our SD Card Wiki. The standard card in a 4 to 32 GB size will work fine. Available on Amazon, or stores like Walmart. Be sure it is in the card slot while sleeping. You will need a SD card reader if your computer does not have one. Also easily available.

Regarding your ASV, it is likely it is set on default values. This can result in a very disruptive range of pressure changes and we can optimize it, however we would be much more comfortable seeing an Oscar Daily Details chart to know your settings and how you are responding to the therapy. If all else fails, be sure your settings for Essentials is set to Plus. This will provide a more detailed on-screen therapy report. We can use that information to get you on track. This quick tutorial shows how to access the clinical settings. Enter the clinical settings and scroll down to Essentials, and make note of the settings for EPAP Min, EPAP max, PS min and PS max. If Essentials reads On, then highlight and click with the control knob and set to Plus. Use the Home button and Exit Clinical Settings. https://www.apneaboard.com/resmed-airsen...setup-info

Once we have your OSCAR screenshot(s), we all be able to help you more. ASV does not report central apneas because it essentially stops them by ventilation. All of the apneas reported as Unclassified Apneas to OSCAR with an ASV are obstructive.

The air pressures can be adjusted. But you can also help avoid the forced air by breathing slowly and in a relaxed manner during the first 90 seconds when starting the ASV. That is when you help set the backup rate that takes over if you have a central apnea. If you avoid breathing too fast when starting out, you will probably have much more comfortable nights. That is what I found out after using an ASV for a while.
