My Wife Keep Waking up at Night!
#61
RE: My Wife Keep Waking up at Night!
Last night I change the pressure setting to 13.6/8 PS4 and this morning my wife did not report any air try to push out the full mask.
I got the figure of 13.6 cmH2O from looking at the results from SleepyHead at the 95% column of the table on the left. 
I picked the date she felt most comfortable and 13.6 cmH2O seem most appropriate.
I am planning to increase the IPAP to 18 slowly over next three months until she accustomed to slight increase of pressure over time!
Meantime, I am waiting for delivery of the Philips Respironics Dreamwear Full Face Mask Fit Pack and I shall keep you posted.

Hi Sleeprider,
Week and a half gone by, and still waiting for the new full mask to arrive!
My wife is slowly getting used to higher pressure with the Bilevel machine, and the AHI is floating between 2-3cmH2O!
Last night result from SH indicate a higher numbers of CA (Clear Airway), but the Rescan shown them to be Central Apnea events?
Are they meant to be the same apnea event, but different interpretation by the softwares?
If it is central apnea, how best to minimize them with the machine?

Clear Airway and Central Apnoea are the same thing the CA's are fairly low so I would not worry for now, if over the next few nights the number in crease then you could try reducing the Pressure support to 3 and see if they are lower.

Hi jaswilliams!
Thanks you for your response and keep you inform in a few days time with the new PS3 settings! 
Thanks

RE: My Wife Keep Waking up at Night!
Gumleafau, I have been gone on a motorcycle trip for the last week and a half, covering about 4500 miles and smiles. The last charts you posted have some CA events. I have mentioned before that your wife has a very low respiration rate, and I'm sure the CA events are related to that. If most of the events are less than 15 seconds, they are probably related to her natural low resp rate and perhaps sleep transition or movement. I am not concerned about settings, but you may want to discuss the respiration rate with the doctor as this is considerably below normal. The therapy she is using cannot affect respiration rate. Whether it is affecting her would require some monitoring with an oximeter.

RE: My Wife Keep Waking up at Night!
Thanks you from taken you time off from bike riding holiday to answered my post!
4500miles in a week and half is quite a lot of riding, so you are doing on average 450miles a day!
I am just wondering will the Resmed Aircurve VPAP ASV be a better machine to treat her CA and low resp rate!
Meantime, I will make an appointment to see a doctor and discuss about her low respiratory rate!
Keep enjoy bike riding!
Cool

RE: My Wife Keep Waking up at Night!
Since I don't know whether the low resp rate is a medical concern, I can't judge the use of ASV, but I doubt it is the therapy of choice. Clearly a bilevel with backup such as ASV or ST can help to induce an increased respiration rate in some cases. My recollection is that she tends to have very long expiration, longer than 5-seconds on average. This will easily be interpreted as apnea or hypopnea when that median interval is even longer. I think you need to rule out COPD that can make expiration restricted. Another thing to consider is a higher pressure support that can make the difference between inhale and exhale greater, and therefore improve the inspiratory volume and make expiration relatively easier. If you have tried higher pressure support I don't recall the results.

Her AHI is not that bad, and the need for changing anything should be based on an evaluation of her oxygen saturation. If prolematic, this might be improved with higher EPAP and/or pressure support, bilevel with a backup rate, or supplemental oxygen bleed into the BPAP circuit. First things first; get a pulmonary workup so a professional can determine if her tidal volume and minute vent rates are being met, then decide on an appropriate strategy only if there is a problem. The AHI at 2-3 is simply insufficient to draw that conclusion.

Can you explain why reducing the PS3 could reduce CA event in sleep apnea therapy!
