The difference between CPAP, BiPAP, and auto-CPAP

A reader asks "I've been on a CPAP for years, but my sleep specialist is putting me on an AutoPAP. In the meantime, my DME has me on a loaner BiPAP and I feel a lot better even after one night's sleep.Also, does the difference in machines do anything in reducing long term complications"

CPAP, continuous positive airway pressure, delivers a single continuous level of pressure. CPAP is usually effective in treating obstructive sleep apnea. BiPAP delivers a higher pressure while breathing in, and a lower pressure while breathing out. BiPAP can be used to treat obstructive sleep apnea and is sometimes effective in treating central sleep apnea. I t can also be used to assist ventilation in various pulmonary and neurological disorders. Auto-CPAP can be used in 2 different manners: 1) to vary pressure during sleep for a person who has varying pressure requirements (for example, needing a higher pressure during REM sleep) and 2) can be used on a temporary basis to do a CPAP titration. In cases in which patients have had a CPAP titration in the sleep lab but I'm still not quite sure of the exact optimal pressure, I sometimes send them home with an auto-CPAP machine for a few nights. The machine generates a computerized printout that helps me pick the right pressure.
In OSA, the differences in the machines make no difference in reducing complications as long as the patient is compliant with treatment and receiving an effective pressure(s).

I have been using a bipap for three years. But i awaken with GERD that i do not have durung the day. Is there a solution?

If you've been on any breathing assistive devices, its important to be re-evaluated annually. Reflux may indicate a need for swallowing studies, but it depends on why you are using the Bi-Pap - if its for a neuro-muscular breathing disorder, a specialist in PM&R/Pulmonary, or Pulmonary/Neuro is critically important - they're few and far between.

I just googled CPAP/BIPAP and lucky for me I got your blog. I'm a medical interpreter and some times acronyms drive us crazy, because they change/repeat etc. The information was perfect, I was interpreting for a south american lady and it allowed me to give her the best definition ever!!
Thank you so very much, I just book marked your blog, I'll check it all later.
Thank you, thank you, thank you!

I have worn out 2 CPAP machines and a Healthdyne PSV over the last 20 years, and now am using a Respironics M series BiFlex with Humidifier. I use a chin strap but still wake up with evidence of mouth breathing. Current pressures are 19/8. Is there anything else you might suggest to get a good night of sleep?

desparate mouth breather OSA - been using chin-ups to tape my mouth shut - but i do not recommend this method

Laura said...

my doctor recommended a sleep study. they decided i needed a cpap machine but my insurance changed and now doesn't cover any of the cost. can i use a bipap machine instead of the cpap?

davidwhite214 said...

@Laura: As far as i know that it is okay to use a BIPAP also than of CPAP machines if you can't afford the cost of the CPAP.

Denise said...

I too as Laura stated above attended sleep study and am supposed to use CPAP but not available to me due to insurance although I had a dear friend pass away last year that was using a purchased BIPAP that here husband has so graciously offered to me to use. Is this typically accepted to do the same as long as it is calibrated & programmed as needed?
Thank you, Denise

BiPAP or APAP, which is better? I am having OSA and central apnea since the last many years with gradual memory loss and glucose intolerance.

can i have some more details on this?

Having used both if your dr will give you a bipap you will sleep better and have much less air bleed...the mask fit is the most important consideration and nose and mouth mask works the best... if you can use it you will get max benifit...

I HAVE BEEN USING A CPAP FOR MANY YEARS ALONG WITH A HUMIDIFER ATTACHED. MY SETTING IS 13. IN THE MORNING I CONTINUALLY WAKE UP WITH EXCESSIVE DRYNESS IN MY MOUTH.
ANY SUGGESTION TO THIS PROBLEM WOULD BE APPRECIATED. I HAVE ALREADY SET THE HUMIDIFER TO IT'S HIGHEST LEVEL AND STILL HAVE THE SAME RESULT. HOW ABOUT A SWITCH TO A BIPAP MACHINE?

MY CPAP IS SET AT 13 AND I HAVE SET MY HUMIDIFER AT IT'S HIGHEST SETTING. ANY HELPFUL COMMENTS ARE APPRECIATED.
WOULD A SWITCH TO A BIPAP HELP WITH THIS PROBLEM?

I have a RESMED SP-9 CPAP machine, new last Dec. I was told I need a BIPAP machine, after a 2nd sleep study. They gave me a loner to try before they give me a new RESMED BIPAP machine. The loner is only the left hand side of the machine, it clips onto the right side of my existing CPAP machine. Every word & number is identical on both machines, except the serial #. Can the RESMED SP-9 be used as both a CPAP or a BIPAP, by programming the SD card? If so why would anyone want me to purchase a new machine?

Tony Wilson said...

I just switched from a CPAP to an AutoPAP and have been able to ditch the chin strap.I attribute that to the lower pressure during exhale. The incoming air doesn't have to have a place to go (which was through my mouth).

Thanks for all of the great information. I just went through two sleep studies, and they found that I too need the BiPap Auto SP machine. I'm looking forward to getting some good nights sleep, without being hooked up to wires!
