[CPAP] Interpretation of ResMed S9 Autoset results

[welshmike]

Thanks again zonk.

I was successful in using ResScan immediately after I started using my S9 in December 2013 and could see the detailed data and graphs for the first month.
I'll make sure that I download all data tomorrow

I prefer to use my GNU/Linux/Ubuntu operating system to Windows and tried the Linux version of SleepyHead downloaded from http://sourceforge.net/projects/sleepyhead/ some time ago but had no success. I'll try it again on Ubuntu and will also try the Windows version on my Windows system.

The S9 SD card stores up to 30 days of detailed data and 7 days of flow data, also up to 365 days of summary data
If you erase the data on the machine and SD card, you cannot retrieve the old data. Tomorrow is another day, ensure the SD card inserted correctly in the machine and stay there all night otherwise we're back to square one
Always select 'discard' when prompted during download in lieu of 'overwrite'

SleepyHead is easier to download, just click on 'import' and you done

Reformatting the card on your computer doesn't matter. The machine will just reformat it again when you put it in. I hope you saved the data that was on it before you erased it. ResMed's greatest flaw is how it keeps data. As in it doesn't.

zonk,

Below is a link to an image of last night's graphs seen on ResScan. Please be aware that I'm making new adjustments to the Resmed S9 Autoset after I have managed to adjust the facemask strap tensions so that I no longer get facial bruising and pain.
I am aiming to get back to my long term absence of obstructives over the last 10 months but this time with none of the bruising.

What do the numbers on the graphs below mean please, e.g. above the Events bars?

Hi welshmike
I'm not knowledgeable about this sort of stuff, I recommend schedule an appointment with your sleep doctor

Hi welshmike, welcome to the forum!

For some reason I cannot open/view your jpg file.

The numbers above the event bars are the lengths in seconds for each event. The minimum number will be 10, because an event is not flagged if it lasts less than that.

Tale care,
--- Vaughn

Hi Vaughn, this might helps

[welshmike]

Hi zonk,

Thanks for the reference.

My "sleep doctors" are a UK National Heath Service respiratory consultant and respiratory nurse technician at my local hospital. They are overloaded with work having responsibility for the care of many hundreds of respiratory patients. My case is not one such that I would get an appointment to see them in less than a month although I will have been using my ResMed S9 Autoset for twelve months by mid December and will be called for an appointment before year end.
So it has been a situation of me taking personal responsibility for my use of my ResMed S9 Autoset.

When I was diagnosed with OSAS in December 2013 my driving licence was taken away and I was given the machine to control my sleep apnoea. I was told to use it for a month and then take the SD card to the respiratory nurse technician so that she and the consultant could decide if I met compliance criteria and whether I could apply for my driving licence to be restored.
I decided that waiting for a month to get feedback about my apneas was unacceptable and I then went down the path of finding out how I could get daily feedback. Hence my postings on other forums and this forum leading to the use of ResScan and the critical adjustment to my natural supine sleeping position to one of being on my side.
I was very happy that as a result of seeing the SD card data and graphs produced by ResScan every day I had satisfactory improvements in a reduction to zero of obstructives and fewer centrals.
However my recent loosening of my mask straps to stop facial pain and bruising has affectively made a new start to my use of the machine.

Hi Vaughn,

Thanks for the info about the number (= seconds).
Those 41 seconds of Centrals may look alarming but are possibly the result of my Beta blocker and other medication and my past training in underwater breath holding. I'm not alarmed them (edit: those Centrals) but must eliminate those Obstructives.

Regards
Mike
P.S. The following may or may not be relevant.
The medication I was prescribed some years ago to treat my hypertension has also slowed down my pulse rate and reduced the strength of heartbeats. This has resulted in my pulse being capped at 90bpm and an insufficient supply of Oxygen during strenuous exercise causing early onset of lactic acid in my muscles and muscle pain

I referred earlier to underwater breath holding and did some online "research" into my Central apnoeas.

I came upon "Cheyne–Stokes respiration /ˈtʃeɪnˈstoʊks/ is an abnormal pattern of breathing characterized by progressively deeper and sometimes faster breathing, followed by a gradual decrease that results in a temporary stop in breathing called an apnea" and also in this thread http://www.apneaboard.com/forums/Thread-...ng-Pattern and Post # 3.
"Some cases, as in certain types of athletes and scuba divers of a certain age, a longer breathing pattern is developed that mimics CSR but actually isn't and is not dangerous. I know this one from personal experience, being a skip-breather form years of diving."

I was a Scuba diving instructor for 30 years, practised breath holding for up to 4 minutes while swimming lengths underwater in the training swimming pool and skip breathing (but not during ascents) when diving in open water.
Also being a regular freestyle swimmer in the swimming pool I had adopted an abnormal breathing pattern.
