Devilbiss DV57D Setup Manual

[LaserBoi]

Does anyone have the Devilbiss DV57D Clinical Setup Manual?
There are some Devilbiss machines in the manual section, but this is an
AutoBiPap and there are some settings that the other manuals don't have listed. Even though I live in Singapore, and the US law doesn't apply here, they still will not give me the manual.
I am currently waiting for my ENT doctor to try to get it, but if anyone has it I would appreciate it.
Thanks,
Michael

Hi Michael,




We don't yet have a copy of that manual, but if anyone does find it, please email it to apneaboard@gmail.com so we can make it available to our members.

Thanks.

Hopefully my ENT will be successful, and I will surely email a copy.
Thank you for your reply and to all that are on the board that help us all with anwsers.

Hi LaserBoi,
WELCOME! to the forum.!
Hopefully, you are able to get the manual you need for your machine.
Much success to you as you continue your CPAP therapy.

Hi LaserBoi, welcome to the forum!

Your profile says EPAP=4.5 and IPAP=13.

The difference between EPAP and IPAP is called Pressure Support (PS).

If EPAP=4.5 and IPAP=13, then PS = 8.5

Another way of writing "EPAP=4.5 and IPAP=13" would be "EPAP=4.5, PS=8.5"

If your prescription is EPAP=4.5 and IPAP=13, then I think the amount of PS (8.5) would be unusually high.

The amount of PS we use can sometimes affect how many central apneas we have per hour, which is called the Central Apnea Index (CAI). If the CAI is only 2 per hour or less, I think it probably would be considered fine, unless the central apneas were sometimes lasting a very long time, such as longer than 60 seconds.

Most machines do not attempt to treat central apneas. Usually, the CAI needs to be at least 5 or 10 before health insurance companies would cover an upgraded machine called an Adaptive Servo Ventilator (ASV) machine which can treat both common obstructive sleep apnea and the less common central sleep apnea.

If your PS is 8.5, this would tend to increase the volume of air you are breathing and the amount of Oxygen in your system. I suggest you ask your doctor to prescribe a "recording" Pulse Oximeter so you can occasionally monitor your Oxygen levels (SpO2) while asleep, to verify your average SpO2 when asleep is not much higher than 96%.

SpO2 in the range 94% to 96% is widely considered ideal. I think 98% or above, if lasting most of the night, may be too high, perhaps unnecessarily increasing oxidative stress and the number of "free radicals" in the blood, perhaps lowering the effectiveness of any prescription medications you may use, and perhaps accelerating aging, atherosclerosis, etc.

Actually, we don't need a prescription to buy a Pulse Oximeter, but if you do get a prescription your health insurance may pay a portion of the bill, if you get it pre-authorized.

I bought one at Supplier 19, which I bought one from and regard highly. (Link to Supplier List is at top of all forum pages.) The wrist-mounted pulse oximeters with separate finger sensor cup are more comfortable and more stable, and I think are less likely to fall off or give questionable readings.

If your SpO2 is too high for much of the night, I would suggest asking your doctor to consider raising EPAP to 5 or 6, so it would be a little closer to 13.

Take care,
-- Vaughn

ADDED: I just realized that you might be in Auto BiPAP mode, with your max IPAP set to 13.

If that is the case, then your PS will probably spend all or most of the time well below 8.5, and EPAP may be self-adjusting to 5 or 6 most of the time.

If your machine is in BiPAP Auto mode, what are the settings for Min PS and Max PS?
