Re: Adjusting Leak Rate to increase CO2

You can always dump your oximeter data to a file and have sleepyhead read the file. I have found that combination of my computer, oximeter, and sleepyhead is finicky, sometimes it works, sometimes it does not. The file method always works.

Re: Adjusting Leak Rate to increase CO2

no mask, to my knowledge, has an anti-rebreathing valve, the f10 certainly doesn't. it has an anti-asphixiation valve, which is a horse of an entirely different color. You are completely correct. The valve flap covers the hose opening in the 'relaxed' state, but it does not seal against anything. T...

Re: Rainout despite heated hose -- aargh!

And position the machine/humidifier lower than yourself when lying down - water won't run uphill. I have the machine lower than the bed and that does help. The problem is that if I leave enough slack in the unheated pig-tail hose to move around, it forms a trap with one section lower than the rest.

Re: Adjusting Leak Rate to increase CO2

To me this is just a one axis robot, and I am tweaking the PID loop. I love the analogy. I tend to think of it in terms of tweaking the noise gain to compensate feedback amplifiers myself. Everyone told me it was impossible for me to be rebreathing, so I did my own experiment. Simply see how much a...

Re: Rainout despite heated hose -- aargh!

Unfortunately the Nuance Pro comes with about 18" of unheated mask hose. My bedroom is COLD, sometimes below 50, and rarely above 60. The last several nights I woke up to the sound of gurgling water in the mask and hose. I shake the water out and go back to sleep. I often dump cold water on myself o...

Re: Machine says high leak rate, but I disagree

Does the leak come and go, or is it constant?

Re: Does salt affect sleep apnia

The government guidelines on salt consumption keep changing. My personal, non-medical opinion is that as long as you are in good health and getting enough water and other electrolytes (potassium) you can consume any reasonable amount of salt without worry. For a normal person, excess salt should not...

Re: Ahh.. the Insurance changed.... WAPITB!

DME charges 1233.00 - $850 deductible = $383.00 Insurance then covers 80% of the balance so my "copay" is $76 From what I can tell, my insurance does that a little differently and only applies the deductible to the portion they pay. It something like this: $1233* 80% = $986 $1233* 20% = $246 (co-pa...

Re: High leakage or machine malfunction?

There should always be some leakage. It is an important part of the mask design; it keeps you from re-breathing your own air and suffocating. The leakage should be through vent holes in the mask, not around the seal. Your mask should have come with a graph that shows the typical leak rate vs. pressu...

Re: periodic breathing

Congestive heart failure? Narcotics? Did you move to a higher elevation?

Can you post a plot of your breathing pattern?

Re: What is a good AHI with ASV? Revised

Now that you have the graphs and information about right, it would be helpful if you would zoom in and show some of the deaths of the individual breaths during the CA and Hypopnea events. This will give an idea of how long they are lasting. The heavy black line above the flow rate chart shows where ...

Re: What is a good AHI with ASV? Revised

I am not a medical expert and I am jumping way ahead here, but if your breathing is too shallow, ASV may not be your best therapy option. ASV attempts to even out your breathing. It does not really attempt to get you to breathe deeper. Now that I can see your graphs in a little more detail, it does ...

Re: What is a good AHI with ASV? Revised

Out of curiosity, how did you arrive at an ASV therapy? Had you tired CPAP and BiPAP? Were the results similar? ASV does wonders for certain types of apnea (like you stop breathing for no known reason or you get into a cycles of periodic breathing) but is not a universal solution to all types of apn...

Re: What is a good AHI with ASV? Revised

EMTUnit- It might be worth getting a recording pulse oximeter to see if those hypopneas are causing any blood oxygenation problems. If they are, you may need further treatment. If your spO2 looks good, then really comes down to how you are feeling. 20 is high, but AHI is just a number. I would rathe...

Re: SpO2, Heart Rate, & AHI Reported By APAP

Do you have any symptoms like daytime sleepiness that would indicate that there is a problem? Mild CA's and complex apnea events can resolve themselves without arousal, and if the are not causing dips in spO2 levels or spikes in HR, they may not be really hurting anything. What is 'ton' of events? 5...
