(11-18-2020, 04:20 PM)Thanks I already have that and more and repair and service manuals but so far no clue on what these setting really do and under what condictions to use them.Rich Sleeprider Wrote: Phalaronic, the titration protocol you attached was for Philips BiPAP Auto. It's better than the ones I've been using, so thanks. Do you have the BiPAP Auto SV from that publication?

RE: Deep tech help with Phillips ASV machine settings
Any success in searching Supplier #2 inventory? They have low hours ASV/SVAuto types possibly even now if a newer machine is determined to be needed by yourself.
If I come across any tidbit of setting info I will pass it on. It does seem I end up with a DreamStation SVAuto tomorrow. I don't mind passing on what I glean out of it. BTW what settings are you using currently on your machine? If these are off any it can throw the whole therapy effectiveness out the window.

Rich, I'll try some brief replies, and you can ask clarifying questions where needed. BPM is the backup breath rate. Guidance is to set this at 2 or 3 bpm less than your normal median rate from CPAP or to set it to auto. Most users just use the auto setting, however, there are reasons for setting this value if spontaneous respiration is very unreliable. A typical value is 12 BPM for an individual with a spontaneous rate of 15 bpm. We would not use a setting of off for anyone that needs the backup rate and in any SV mode. Ti gets more complicated, but typical values are 1.2 to 2.2. We may use a shorter time of inspiration for someone that has COPD that needs expiration time preserved due to impaired lung function. The idea is to give sufficient time for inspiration but not let it drag on to where the patient does not have time to exhale. If we assume 15 breaths per minute, the breath cycle is 4-seconds per breath. A normal breath would allow for 1.5 seconds of inspiration, leaving 2.5 seconds for expiration. If the normal breath rate is 12 bpm, then with a breath cycle of 5-seconds, Ti might be 2.0 leaving 3.0 seconds for expiration. The idea is to create an normal breathing rate and generally a I:E ratio of less than 1.0 Mask resistance settings are less important than this guidance suggests. Different masks have different volumes, and setting this value correctly may help the machine to compensate for that volume in achieving flow and pressure. Philips also says to leave it at 0 or off for non-Philips masks. How important could it be?

RE: Deep tech help with Phillips ASV machine settings
Your EPAP min is very high for ASV. That does not mean it's wrong, but it affects expiration pressure which increases flow limitation. I don't recall how you got to these pressures, but you are on the bleeding edge of individuals using ASV. If you want to try the Resmed ASV, Supplier #2 might be a possibility. Using your Philips, have you considered starting titration over and seeing what happens at lower pressures?

RE: Deep tech help with Phillips ASV machine settings
I Have the Titration instructions, and as per the instructions I raised the EPAP min until I can almost stop all obstructions, and the raised the Pressure support currently it is 5.5 to stop most of my Centrals and as much Hypopnea as I can.
I have been trying lower epap min but my obstruction climbed to a 6+ AHI level.My sleep studies have reported that it takes 10 to stop my snoring and most of my obstructions. I had pushed for all zeros and was getting them at 13.5 and 19 but it seemed to have cause some Gastritis caused by CPAP. And there are other disorders that can be caused by CPAP, this has had been an eye opener…I NEVER in the seven years I have been on CPAP heard or read all of these. As I was having some Digestive and gastrointestinal problems, lately so I looked into it and here is what I have found: Digestive and gastrointestinal problems are not commonly thought of when you mention obstructive sleep apnea. Although CPAP therapy is one of the most successful methods for treating and reducing the symptoms of sleep apnea, there are a host of CPAP side effects that may follow after constant use of sleep apnea equipment. If you wear a CPAP mask and use a CPAP machine, these issues might sound familiar to you. Aerophagia This is the medical term for eating or swallowing air. This generally occurs when the CPAP pressure is too high for you and can result in gas and bloating. Discomfort: Wearing a CPAP mask can sometimes cause discomfort when trying to sleep. The mask can feel bulky and constrictive, and the hose can get in the way of trying to sleep in positions other than your back. Exhaling can also be uncomfortable if the pressure of the sleep apnea equipment is too high. Claustrophobia Many people feel claustrophobic while wearing a CPAP mask because the mask fits snug around your nose. The feeling of claustrophobia can be even worse for those who wear a full-face mask that sets around your mouth and nose. Mask Leak If your CPAP mask does not fit properly or isn’t properly cleaned, it can cause leakage. When there is a leak, there is a high probability that your CPAP machine isn’t able to reach its set pressure. Dry, Stuffy Nose or Nosebleeds Having a dry or stuffy nose is a common side effect of CPAP because air from the machine is being blown into your airway. This constant flow of air can also cause nosebleeds to occur. Skin Irritations Because CPAP masks fit snug against your face and are worn repeatedly, your skin can become irritated. This CPAP side effect can result in skin irritations such as rash or pressure sores. Dry Mouth Suffering from a dry mouth is yet another common CPAP side effect for those with a full-face mask, as well as patients with a nasal mask who breathe out of their mouths. Infections If a CPAP machine or CPAP mask isn’t properly cleaned on a routine basis, infections, such as lung or sinus infections, can occur. Headaches Although headaches are not a common CPAP side effect, they can occur if the machine’s pressure is set too high or if you have a blockage in your sinuses. Lung Discomfort Some patients who use CPAP therapy complain of a burning sensation in the lungs. This is often a result of dry or cold air being inhaled from the CPAP mask. This CPAP side effect can possibly be reduced by using warm humidification. Dizziness Some complain of dizziness after wearing a CPAP mask. While the mechanism for this symptom is not clearly known, some believe that this might be due to the pressure change in the middle ear. The symptom should be short lived if due to CPAP therapy. Shortness of Breath While another common CPAP side effect is the complaint of shortness of breath, this feeling is usually sensorial. It is merely the sensation of not getting enough air because a functional CPAP machine never reduces the amount of air that can be inhaled. Even though there are side effects related to using sleep apnea equipment, it’s important to be compliant with continuing to wear it. Not using your CPAP mask and machine as prescribed can cause larger, more severe health problems such as fatigue, high blood pressure, heart arrhythmias, heart failure, heart attack, or stroke. How to help Prevent CPAP Side Effects If you’re experiencing any of the CPAP side effects mentioned above, don’t give up on the treatment just yet. There are solutions to these common problems. Try these different strategies to reduce or completely halt your CPAP side effects. So as you can see I am fairly well informed. Rich SleepriderYour EPAP min is very high for ASV.

RE: Deep tech help with Phillips ASV machine settings
I'm of a mind that you might want to back down the EPAP and PS Min a little, maybe several small reductions, to see if it becomes more comfortable. Check OSCAR stats as you do this to see how it affects apnea events. Weigh events vs comfort and attempt to get a balance.
I see OSCAR stats have you at 2.x AHI but the SVAuto is giving almost all its got to get to events lingering. Subpar if I were asked. As is according to OSCAR, these settings are not cutting apnea down to reasonable levels. Is it possible you need to go to some other treatment machine, because this doesn't look acceptable.

RE: Deep tech help with Phillips ASV machine settings
Thanks for the summary of your titration progression. You already know all the basics I could possibly contribute. This is an excellent history of your progression, but unfortunately, I can't improve on your work. You have done everything right. I wish I could improve things to accomplish your objectives, but you have taken all the right steps and clearly understand the titration protocols. I was trying to address the questions you addressed in the original post, and will leave this conclusion. Zero events is an unrealistic and unnecessary goal. We often make changes in therapy settings to increase comfort, reduce events and other objectives, and have to make compromises. When therapy is within range of "efficacy", these trade offs can be very subtle. It seems you might be at that stage.

I suffer from hay fever which can cause some blockage, at least that is what I believe as I some times wake up and coff up a mess. Now you have raised some questions: So here is a overview: [attachment=28201] And a couple of good nights with the first weeks of going for zeros not the epap and pressure support settings: [attachment=28203] [attachment=28202] So what is wrong??
