sleep study using cpap - sleep4 - 10-07-2020 Hi folks: Can I use the Resmed 10 Autoset to do a sleep study. What I mean by that, is to use it to only find AHI without giving actual pressure? ie: similar to the sleep study kits that are sent home (ex: ResmedĀ ApneaLink Air) Thanks RE: sleep study using cpap - Gideon - 10-07-2020 NO. Anything you get from the AytoSet will have at least 4 cmw support. If you get greater than 5AHI at that pressure you can conclude that you definitely have apnea. if less than 5 only that you are 'well treated' at 4 cmw. This can be done to see if it makes sense to do another sleep study to see if you are actually apnea free. RE: sleep study using cpap - sleep4 - 10-07-2020 Ok, so you would set min and max pressure to 4 and check the AHI index for the night? would you do any other setting for the test, ERP, etc? RE: sleep study using cpap - Gideon - 10-07-2020 EPR will lower the pressure of 4 to 4, in other words it will have no impact. Personally I would check OSCAR charts as they are far more complete than just the AHI. RE: sleep study using cpap - sleep4 - 10-07-2020 yes, I understand ERP now. so basically setting min and max to 4 will enable to test for apnea with OSCAR data? Is this something that people usually do to save on the sleep test? Thanks RE: sleep study using cpap - Sleeprider - 10-07-2020 You are not listening. Using a CPAP pressure of 4-cm means you are receiving positive pressure therapy. The only thing you are testing is whether 4-cm is sufficient to treat obstructive sleep apnea if you have it. A sleep test is done without the benefit of positive pressure, and measures respiration rate, flow, volume, effort, sleep state and arousals using a variety of sensors. No sleep study is conducted using the therapy used to treat OSA. That would be a titration test. RE: sleep study using cpap - Gideon - 10-07-2020 Honestly no, since that suggestion is usually delivered with the fact that very, very few actually are 'cured' of sleep apnea. Once you have a pap that has detailed data you don't need a sleep study, except for a very specific purpose such as proving efficacy for an ASV. OSCAR data is sufficient to determine therapy direction, and has at times led to non-pap solutions. Also because most adults have issues with breathing at a pressure fixed at 4 cmw. |
