I have Central Apnea. Was diagnosed in November. I was put on a Cpap machine in August (resmed Airsense 11) Immediately my events per hour were between 55 and 70. In December they did a second in hospital test and confirmed the diagnosis of Central apnea. It took almost two months to get the insurance to agree to a ASV machine. (resmed aircurve10 asv) Recieved it 2/1/23. The first readings I got were last night and the events had dropped to 2.4.

You have been MUCH more help to me than the therapist that was assigned to get me set up with my cpap machine. They wanted me to just accept that they know best, and not to know about the machine, how it works and what it does. You've really helped me become educated, adjust settings, and I'm doing much better because of your help. Thank you!

Brother, this one video has helped me more than the sleep therapist and doctors I've dealt with in the past 5 years. These so-called professionals just send people out the door with a cpap and don't do shit else.

I have both obstructive and central apnea, AHI at sleep test 7 years ago was 145. Nurse said highest she'd ever seen. I jokingly describe central apnea as "my brain trying to kill me." Is now well treated with AirCurve 10 ASV and 1.5 liters oxygen, only ox now at night. AHI is now 1 to 2. I got off daytime ox when I moved 2 years ago from 5000 feet above sea level to 2500 feet above sea level. 4 years ago I had surgery inside my nose, while they were up there they found and removed a piece of a plastic toy that had been in my Middle Meatus for probably 50 years. I don't recall it going up there but I breathed better once they removed it. I have an endoscopic photo of it up there, that my surgeon gave me, if you'd like to see it.

Thanks mate for the ASV tutorial. I was curious about what the difference was between ASV and BiPap. I am so happy for Fred and commend Susie for all she has done to get Fred on the right path. Heaven knows this poor man has been through so much.

Hey Nicko, I have been using a Res Med ASV for over 5 years. Cheyne-Stokes and Complex Apnea, etc. No one ever explained to me as you just did how this all works. I recall looking at the display for hours and trying to make sense of MV and Tidal Volume and all that. Now I think I can understand what is going on! Now it is time for me to replace the motor in my Air Curve 10 ASV and I understand a whole lot more then when I first got prescribed for ASV. Been a CPAP user for more than 20 years. Thank you so much! Bill in California

WOW! I'm really surprised that a BIPAP machine can control central apnea using pressure changes alone. When you mentioned Adaptive-servo ventilation, I picked up on the word "ventilation" and envisioned something more on par with a hospital ventilator... something that takes over the patient's breathing. An ASV is just a very smart BIPAP machine that can sense that pattern and adjust the IPAP/EPAP differential and actually fix CA! That's amazing!

Awesome story. I was very fortunate having a great sleep doctor. My untreated ahi was 74. For the machine titration, cpap failed to make any difference so I ended up with the Aircurve 10. After a few weeks my ahi remained between 10 and 30 so my sleep doc ordered a second machine titration with bipap with a backup rate and ASV. The ASV option ended up working for me with my AHI consistently being around 1 or less. Dealing with insurance was a bit of a pain though but worth it in the end

I love this explanation, Nicko. _Thank you._ One thing comes up in my mind when I read about ASV,. bipap and other more complex algorithms than straight CPAP. US Patients are essentially penalized by ResMed for having to use ASV or BiPAP. The machines are much more expensive. Ironically, the hardware is identical. It's only the firmware that's different. This was borne out during the pandemic when a firmware was made available to unlock regular AirSense 10's so they could be used by hospitals where there was no access to more complicated breathing assistance machines. It disappoints me that ResMed penalizes people who have more complex XPAP needs by making them pay more for essentially the same hardware with different firmware. This aligns closely with the "right-to-repair" and "right-to-health-care" movements that large corporations don't like. I'm curious where you stand on making people with more complex issues pay more for essentially the same machine.

Thank You. Recently diagnosed with OSA AHI 35. Started with CPAP for 1 week doing fine with AHI in 3.6 and then did an ABG with Pco2 in 54 compensated so switched with Bipap( same device as yours). Used one day AHi at 1.3 and then boom….. AHI 23.4. Looks like treatment emergent CSA….. if I fail in next couple of days I will switch to ASV

Congrats on helping them that's fabulous!! 👏 I've sent so many people to your channel bx I work for a DME company and they're always looking for help and I've tried very much to help all my patients and you're my best kept secret I share with everyone thank you for all of for knowledge

Holy molly. I felt so bad for Fred but then bam, you show us how he switched modes and then his AHI goes waaaaay down. This is amazing.

WOW 😀👍 Priceless information. I joined Sleephq's site and analysed my first cpap data. In our country public healthcare is free, and they borrow cpap devices free as handicap aid. Instructions and examine too. But this can take year, because lack of resources. On private healthcare can get quick, but it costs thousands. I found this channel and bought first ResMed 10 personally. Not without reason; my snoring stopped and sleepiness past away. Sorry my english. THANK YOU!

Every time I watch one of your incredibly informative and educational videos...I go dig through my SleepHQ data to compare what I’ve learned to my own info. Of course, there are times when I’m left scratching my head, having a wtf moment trying to figure out why they said I have osa but most of what I see is central...considering contacting the doc to see if they can look at this data and explain...and if we need to make any changes. So grateful you are giving us the tools to help take control of our health care.

I had tears of joy for him when you showed the results for the asv

Great explanation of how servo ventilation (from ResMed literature) and other modes work for central apnea, Cheyne-Stokes or hypoventilation. I just wanted to add that at the end, they waveform (ventilation) kicks in by either the back up rate that is set by the clinician or the minute ventilation. When it senses the apneic period, the pressure support increases meaning the machine will make the inspiratory pressure greater to more simulate a breath so the machine is basically giving you a breath like a ventilator during that time. Anyone feel free to object if i said anything incorrectly. Philip, keep up the great work. I would say about half of the patients that needs some type of PAP therapy device, do not wear it because of the different reasons out there that are not fixed for the patient or explained. Its great to see how you are helping patients become more compliant by explanation....at least someone is doing it! I will take a look at the site since I have been out of the RT loop for a bit doing IT work but I am back to being an RT and love it.

Thanks for this video, I have been using a Resmed CPAP and Now APAP for 20 years and NEVER had such a clear explanation of what it is and how the machine interacts with Sleep Apnea. I also learned from watching one of your other videos that I don’t have to be locked in to Resmed price gouging for service and repairs and can purchase an after market turbine for my Resmed Airsense 10 directly from you. Thanks again for your instructional videos, web site and for the after market spares and advice you have. 👍🏼

ASV has really helped me. If anyone is unhappy with their numbers on their biPAP, I highly recommend giving ASV a try.

In America and had a home sleep study a year ago with the results getting me a CPAP. After the DME provider and pulmonologist reviewed my data, I was given an overnight lab test. It showed complex apnea but it was too late in the study to hook me up to a different monitor. So after a third sleep study, I was prescribed an ASV unit last Dec. Grateful for how well my local DME provider and insurance company worked together since I had CPAP for a couple months before switching to the high prices ASV. I tried a few months ago to download my info to SleepHQ but couldn’t get it to work. I need to try again as I find myself extremely tired the last few months. Thanks for getting in the weeds and explaining exactly how an ASV works!

This was superb. I have been on ASV for 8 years for complex apnea and never really understood how it works. This description was brilliant with great graphics and slow enough delivery to be grasped. Thanks so much for this great production! Subscribed!

I have dysautonomia. My neurologist said that the 1st clue that I had dysautonomia was the diagnosis of Central sleep apnea courtesy of the sleep specialist/pulmonologist. Unfortunately, since that diagnosis I have then received several more diagnoses that should have clued into me getting a diagnosis of dysautonomia. The pure craziness is that the diagnoses/symptoms of dysautonomia all started after having MERS (middle eastern respiratory syndrome- caused by a coronavirus) even though I live in the USA, never traveled outside of the eastern seaboard much less leave the country, I didn't travel in the time before diagnosis of MERS or had known contact with anyone who had the specific virus.

From the States, but love your channel. I'm a ResMed AirCurve BiPAP user. What a difference it has made! My nocturia is completely resolved. Research revealed that sleep apnea (I was diagnosed with an AHI of 45.9) causes nocturia. Wish I had been diagnosed years ago. Thanks so much for your informative videos.

Thanks for the video Nick! I was diagnosed with CSA with an ahi of 124 about 8 months ago. I still struggle to wear it for even just a few hours each night. I've been trying to learn as much as I can, but this video alone taught me more about asv than my Dr has. Appreciate ya!

Thanks for the very clear explanation of Cheyne-Stokes and how the ASV handles it.

I was diagnosed with central sleep apnoea after my first brain surgery for Chiari malformation (ironically). This is what started my career in sleep science. Thankfully neurosurgery has dropped my AHI from over 30 to 0. Now I’m dealing with hypersomnia with sleep instability seen in CAP EEG. I used ASV for awhile but found it really difficult years back so committed to using my experience to help others and gives me great empathy to what emotions some may have starting PAP therapies.

Wow My H is now in need of cpap..Im retired RRT and im now just getting into trying to determine all the information for best machine etc. Found your videos and you are such a huge help! Funny I had the same reaction like holy shit that this discussed mans case got better with another piece of equipment. Really incredible and brings all my knowledge back from my hospital work days. TYSM My main concern is the mixed apnea for my H and the air sense 11 they want to prescribe. We are new to this and thinking to use the 10 with the sd card? Ugh computers are not my thing but I see the value in collecting the data!!

I have watched many of your videos and would like to thank you for giving people the information and education we need! Keep up the great work sir.

I had a sleep test and was stop breathing 32 times a hour. Ive been on cpap but still tired all the time. Trying my BPAP tonight. Hopefully Ill get my physical energy back.

I lived in Singapore and the suppliers I called in to for Resmed, told me they only have a Aircurve 10 VAuto, and they don't carry any others..... I have CSA, I just had a loan set (for a fee) and it's reporting I have CSA (AHI 20+) as the bulk, and I am still trying to figure out the settings, hopefully it "reminds" my body to breathe.... Will logon to your website now. Thank you for doing what you are doing to help everyone

I am on BIPAP ASV...My current 90 say average is .09 Yes that is right. Less than 1 event an hour.

This was an excellent explanation of what happens when you have central apnea and it really incredible how this person problem got resolved. This was very important teaching and done in a way that understandable. Thank you. Truly love your channel

Thank you for the great information that is in your video. I have been on CPAP since September, 1998 and tonight is the first time I have seen this information. This is great.

Very well explained 😁 ! Since i've been following this channel, I learned a great deal on sleep apneas.

He must feel like a million finally ! Great success story ! Love your channel Nicko! Because of you I didnt give up on my cpap last year and became successful sleeping ! I feel so much better ! Thanks again sir !

I was put on a bipap about 6 years back and I just never noticed improvement after a couple years. My sleep study showed 58 events per hour that were almost all classified as central events. Now that I’m getting another sleep study I’m going to keep this info in mind because I wonder if I was getting proper treatment with the bipap and that’s why I ended up just not using it anymore. Thanks for the info

Wow great informative video. These machines when used correctly are life changing. Thank goodness for ASV.

I have no experience with complex apnea and ASV devices whatsoever and found the video very interesting and informative. At the moment CPAP is working well for me but I see this as something for me to be on the lookout for in myself and anyone who I find out is struggling so I can get them to a sleep specialist if their therapy isn't working. Thank you.

So awesome to see you so passionate about helping these patients! Good on you, mate!

Best Sleep Apnea Info out there! Thanks for all your time educating us.

Very interesting topic and well explained. I definitely felt focused on the topic and walked away educated instead of confused. This is why I follow your channel.

Thanks, you are the King of CPAP knowledge. Keep it up mate.

I use resmed Aircurve 10 ASV on ASVauto mode and have been looking for an explanation about it and CSA. Thanks for the explanation of why the machine works so great for me!

One tip to lower your CA. Disable ERP, be careful on high pressure. If i put my pressure high and Erp enabled I also get CSR..

Great tutorial, thanks Nicko, great turn around.

Thank you very much. I suffer from Central and Obstructive apnea as well. I have been on a Dream Station ASV for 3 years with not good results. I just had a new sleep study that I hope will result in a new machine and different settings. My AHI averages 14 but my daily AHI ranges from 9 to 28. I have terrible mask leaks and aerophagia as well. Your videos are helping me understand my condition and possible solutions.

So much great info. Much more than I ever receive locally by my physicians or sleep clinic staff,. Thank you!

Thank you! Wow, this video exactly captured my situation. My pulmonologist mentioned an ASV machine but decided to go with a BIPAP (my CPAP machine wasn't doing the trick). I've had the BIPAP machine for two weeks...and my AHI is worse! AHI's in the 30-50 range. She lowered the max pressure and it didn't have any effect. I'm sending this report to her to see if we can arrange for an ASV machine. Thank you again.

Wow, I'm new here and kinda new to the cpap life, I just started using my dream station 2, I used the dream station 1 for a while before it got recalled. One month in I still feel like crap, not sleeping well and I don't even know what type of apnea I have. I guess as time goes my doctor can look at my dream mapper data. It's overwhelming to say the least, thank you for your videos, I have a lot of research to do

Thank you for all this info, sounds like something I might have to look into. Cheers Cobber have a great day

I’m being tested soon because they think I don’t have obstructive apnea but central apnea. I’ve learned so much from this tutorial. I have never seen my readings not have I been given any info about apnea at all. Hopefully your site will help me learn obviously more than from my Dr. Thank you

Incredible vid mate.... You got skills, nice job

I was diagnosed with central/complex sleep apnea 15 years ago. I started of with the Resmed VPAP adapt SV. I loved that machine. It was a tank and weighed close to 3 times as much as my ASV. I think I slept better with the older machine although the results on paper on similar. It seemed to react faster to events than my ASV. I attributed it to the separate monitoring tube that went from the just below the mask back to a separate port on the machine.

That's awesome, Nick. Will check my data tomorrow for CSR... I have an appointment next week with a sleep neurologist to review my SD card. This is really invaluable. My ahi isn't this bad, but it's weirdly variable from 1.4 to 21.

the second graph makes mine look like im absolutely breathing at random as opposed to stable

Wow! Thank you so much for this video. It did more to help me get any sense out of my data than anything I've seen before.

Fantastic explanation of this technology and so clearly presented! Thank you for the tremendous job you do and help you provide.

Excellent demonstration and explanation. This has improved my understanding of my CSA. Thank-you! 😊😊

Wow. This tutorial is very helpful to see someone receive relief with their apnea issues. I've been on an ASV unit for nearly 4 years after cpap and bipap equipment for the previous 15 or so years. My AHI varies from 13 to 23 with an average of 17. I recently had my 7th sleep study and the report is that I do not have sleep apnea. I find this hard to believe after such a long time. I have been sleeping for 6 weeks now with no pap equipment and I find that I am very fatigued and require a nap each day. Also, my smart watch picks up a lot of severe snoring which was not there with the pap equipment. I do not know what to do at this point. I am trying to get an appointment with the Pulmonologist who read my sleep study to see if there may have been an error with the sleep study. I am 76 years old. Crazy huh? Help.

A great explanation of fairly involved respiration characteristics. Thanks Nicko! I have decided to continue breathing!

Well explained & informative as always. Cheers

I pick up my CPAP on Wednesday. I doubt it's going to work. I believe I have Central Apnea. I have never been much of a snorer. If Apnea is the underlying cause of my issues then I have had this since I was a little boy. I hope that when I get the CPAP it will track my data to give us a clear indication of the type of Apnea I have. I think the Doctors always just assume it's OSA because its the most common. I'm also about 50 lbs overweight. I have not been this fat my whole life. I use to be really fit and skinny as a rail and had all the same issues I have now. We just never linked to to Apnea until last week. I pray to Jesus this works because I don't know where to turn if this dont fix my issues.

Great video, I'm getting an AirCurve, but I don't know which model yet, so I have sent an email to the DME company to find out which. I feel I am armed with more knowledge watching your informative videos.

Great job helping out the person. So their doctor prescribed the wrong machine? And why aren't all these features in all devices. It's just software right? These machines need to determine the issue and adjust so patients are not wasting time.

Amazing video! detailed,no bs, very valuable info. Side q: ASV machines are $3.5k?? why are these things so much $, out of reach forr anyone without good insurance?

Ihave central sleep apnea I was upgraded to a BIPAP ST about 6 months I still have to take meds for the chronic fatigue.. I need we understood what this condition really is.. I was just told that my brain falls asleep and i stop breathing at times throughout the night.. I just came across your channel.. I've never heard of ASV? THANKS FOR SHARING YOUR KNOWLEDGE!

How wonderful that such improvement was achieved!

Thank you for explaining in < 15 minutes what no sleep doctor or therapist has been able to explain in all the years we have been dealing with my husband's sleep apnea! He was finally approved for ASV recently after fighting for it with three different sleep doctors and probably 6 different sleep studies. The difference has been dramatic and hopefully life-changing.

I have complex sleep apnea, and my body fights my bipap. I didn't use it for over 2 years because of the recall. I recently corrected the issue by removing the foam. But since nothing negative happened during the 2 years I am questioning my diagnosis! I will continue to use my machine, but wonder if I need to!

Nick; my DR. told me that I may have a touch of Central Sleep Apnea along with regular sleep apnea. My AHI dropped like a rock since I got my Air Sense 10 to under 10 episodes a night.

I have BOTH CSA and OSA..per my Dr from my recent visit, I have half and half events each night..my initial test was 10 episodes per hour in July 2021..

Great videos Nick and greetings from India Your videos are very helpful I was diagnosed with severe OSAS with untreated AHI of 65.3 and oxygen level dropping to 72%. I have been using resmed airsense 10 since a week and my AHI is below 5. The sleep apnea along with Factor V leiden was causing me to develop clots.1

What a captivating information! Thank you!

Well done Fred!!!!

It sounds like these videos are mostly being seen by patients. I’d like to stress to people if you develop new cheyne-stokes respiration (or a lot of central’s are showing up in your compliance data), it’s important to be seen by a cardiologist to find the cause. ASV shouldn’t be used by people who develop a level of heart trouble where the LVEF is less than 40%, so you should get an echocardiogram before using ASV.

How does one get a detail report with the graphs/breathing report? I don’t have a doctor (self diagnosed)! All the doctors I went to see for my insomnia just wanted to prescribe Sleeping pills, told me to go for walks, which I do to stay in shape. I did my own research and the reason my brain didn’t want to fall asleep is because it knew it would starve for oxygen! So, I purchased a brand new ResMed 10 (Auto). I have my pressure set at 7.8-8.8. It goes up,to 8.5, avg. AHI are less than 1.

I was just diagnosed with complex sleep apnea. I should be getting my airsense 11 in about a week. I subbed to your channel to learn how to maintain my device and learn to read the data when I begin my therapy.

Aaaand of course, the ASV is 4 times as expensive as Bipap! The change is probably only software which is a high R&D cost but minimal long term cost.

So interesting! Stay on the cutting edge!

1. Do you think a standard Auto Cpap can tell the difference between Central and Obstructive Apneas? I have an Airsense 11 Autoset. It is reporting few events, nearly all of which are "Central." But I feel like it is not helping me much at all. I had a sleep study two years ago. The report said I had "moderate to severe" apnea and all my apneas were Central. They prescribed a CPAP. When I found out what "central" apnea was, I questioned whether I needed and ASV. Three doctors (all in the same office) simply said "Ok, then your apneas are obstructive." One told me, "Your insurance company is never going to pay for an ASV."

Thanks for the information. I appreciate it

I have been diagnosed with central apnea. CPAP did not work for but after a second sleep lab test I was prescribed ASV. It works great and I can use for several hours. The problem I have is with my partner, she cannot sleep because of the sound of my breathing or sound of machine. She gets up early and wakes me at 4 or 5 AM and says I can put on the nasal pillow mask. I put it on but will get up at 7 or 8 AM so I only get 2-3 hours per night of ASV sleep. My event index in the lab tests were 60-70 per hour. So my worry is I’m getting too many hours per night (5-6 hrs) with deprived O2 due to central apnea and not using ASV. We don’t want to sleep in separate rooms but I don’t know what else to do.

Could you make a detailed video explaining exactly how I can interpret the information shown on the Sleep HQ dashboard

probably added years onto this mans life, if your not proud about what you do. you very well should be.

I’ve just started on a cpap . My test results was 107 for 5yrs sleep. I’ve been using cpap for 5 days, I’m getting 5hrs still 2but my events are around 55 to 70 over my first 6 days. My specialist in hospital said ut needs to be below 20. I’m on a setting of 12.

This is useful! I did a home study and diagnosed with moderate osa. But now on cpap both numbers are low but my central ai is higher than my other numbers. I’m really struggling to get through the night even on lowered pressures.

love Nicks no nonsense no bullshit opinions! 😂

Thank you from 🇨🇭 for speaking nice and clear 🙋‍♀️🙋‍♀️🙋‍♀️🙋‍♀️ Silvia

My 90+ father has Cheyen Stokes (I know it just by watching him breath in his sleep). He has used CPAP for years and apnea is his single health crisis. It is now starting to affect his heart (arrythmia) and cognition. I know he is older but I totally believe his SA is behind a lot of this. They told me he has lots of of central events 65/hour (but didn't specifically state CSR). Watching this video I am sure that is what it is. It has taken forever to get him a sleep study here in Saskatchewan Canada ... but finally he got one a few weeks ago and they swapped out his Resmed CPAP for a Resmed Aircurve 10 (I'm off to his place to make sure it is the ASV). My question is .. how long does it take for the ASV machine to figure out his CSR events and find that nice smooth (flat) minute ventilation setting. He put it on for the first time last night and I noticed the big differences between the air pressures initially (he noticed too). They had set his initial pressures to 19/9 with a 10 minute ramp up, but he only had it on for a couple minutes. If this isn't an ASV machine they will be hearing from me right away. Comments appreciated.

I so love your channel. It's helped me so much.💕

Many thanks for this great video Nick! And also for the software you are running online at SleepHQ. After purchasing my ResMed Airsense 10 Autoset, without the wireless capabilities, your SleepHQ page came to the rescue nicely! I can see now all my data. The amount of info is amazing, and I am slowly learning how to use the machine, and sleep better. Great work you have done mate, deeply grateful for your instructional and honest videos. Congrats to all involved. Thank you!

Great explanation and video. What I do not understand is why dont they just make one machine that treats both OA and CA. It seems that ASV is just different algorithm to treat CA from CPAP. I think they want to make money by classifying two separate machine types ... rubbish if you ask me....

Thanks Nick. Great Vid. If money was no problem and or ASVs were the same price as a CPAP, should every one be on one instead of CPAP or BIpap? Are there any downsides? My doc will write me a scrip and I would buy it my self. I have CA and I see like 5 CAs a night. Good idea?

Great video Nick, and an excellent example of how the ASV machine treats central apnea. Doctors still seem to fart about with bilevels and so on - are they afraid to take the step to ASV? By the way, where can I get one of those great reverse-printed caps? :)

Doesnt this treatment good for all patients? It sounds like a good idea to have the goal of keeping breath air volume steady.

Thank you for your explanation and information

I'm a paramedic and was going to say it looks like Cheyne-Stokes!

you are the man thanks a bunch fella

This is scary. I thought BiPAP was designed to treat central apnea. I don't really get why it was failing here. I've just been diagnosed with central apnea and they're saying I need a BiPAP. Now I'm wondering if that's going to be a waste of time.

Thanks so much for explaining the theory behind it, so it basically breathes for/with him? Very clever. I thought my APAP was doing the same thing but I guess not!
