Hahaha:-) Yes, I remember now.:-) Fact is that Philips has never once used the name SoClean in their findings, but yes they do say "Ozone cleaning equipment" can damage the sound abating foam... So they just have to prove that Ozone does in fact damage the foam (which I imagine they can, very easily and they have the US FDA findings on their side too). Fact is that SoClean's entire net worth is pocket-change in comparison to Philips Respironics, so they must know that they simply don't have the stamina to go the long way in a court battle and be able to prevail. A very ill advised move which will cost SoClean dearly at the end.

It will be interesting to find out the details. I wonder how SoClean was even licenced to sell these Ozone generators for home use? They are so seriously dangerous.

On what grounds would SoClean be able sue Philips? For having machines that SoClean destroyed with their SoClean ozone contraption and caused Philips hundreds of billions worth of damage?:-)

Agreed. I think that Phillips will eventually go after them.

All I know is that Boston based Respironics invented its first medical CPAP machine in the mid 70s and later was taken over by Philips in the 90s and then California based Resmed started under their current name in the 80s,long after CPAP already had a market , so I am pretty sure Resmed didn't have to reinvent the wheel:-)

I only use dawn and since I only use distilled pure water, I don't worry about mineral build up .

By the way medics advise against using tap water in CPAP in order to reduce chances of water solubles and water born pathogens, getting into the lungs.

SoClean is an ozone generator and circulates the ozone through the entire circuit of your gear, from the mask through the hose and then the machine's internal turbine chamber in order to sanitize it, but it leaves dry scum from rain-out in the tube and saliva in the mask, leaving a dry residue behind, which is most likely the flaky white stuff you see blowing out.

Ozone is also known to degrade inorganic compounds like foams, and materials used in insulation, the primary reason behind another company (philips) to make their historic recall of their equipment because they found that the sound abating foam inside their machines breaks down when exposed to ozone. It could be that materials inside your machine are being broken down by SoClean ozone OR somehow external debrie is getting inside of the air circuit which is then blown out, on startup. You may also wish to read up on the US FDA's take on equipment like soClean:

"The FDA performed some testing, and found that the devices claiming to clean CPAP machines and accessories generated unsafe ozone levels in the area (probably because it leaks into the room)"

Well there is a clear scientific observation that connects patients with CHF to CSA. So they believe that CHF can lead to CSA and vice versa. Some scientists want to start studies into whether or not the development of CSA is a natural response to CHF in order for the body to moderate its PaCO2 levels...THAT is way out in the woods for me:-)

Studies also show that "treatment emergent CSA" is a thing, meaning that the long term CPAP therapy for OSA, leads to the development of CSA. (Remember that CSA itself was only isolated as a disorder back in 2008 at Mayo clinic so it is a relatively new subject and under intense study, internationally.) BUT I have also seen studies that suggest " treatment emergent CSA" will go away by itself within 6-8 weeks, after OSA CPAP therapy stops, but who would stop their therapy, unless they get an "implant surgery", like "INSPIRE" at a cost of like $30 K.??

This being said, it does not mean that people can't just develop Central Apnea without CHF (I am an example of that). There is also a clear scientific consensus that "UNTREATED CSA or OSA" will eventually lead to all kinds of Cardiovascular issues, including and not limited to CHF, however it is believed that the long term use of opiates can also be a driver of CSA.

As to O2 therapy for patients with CHF and Centrals, it makes a lot of sense because CSA folks (again like me) can watch their blood oxygen saturation level (SpO2) drop significantly overnight, if they are not using ASV therapy. I would imagine that supplemental Oxygen used in conjunction with PAP therapy for this group (CHF+CSA) would be very efficient and beneficial because CJHF itself is a cause for lowered SpO2.

Right, so if the patient's breathing is all over the place due to a respiratory issue or sickness, then Resmed's algo will be calculating faulty backup:-) This is why a Dreamstation algo has BOTH choices, an Auto Backup calculation OR a manual backup breath rate, manual Inspiratory time and even manual setting for the "RISE time", the transition time between IPAP and EPAP. Clearly they have worked a lot more on Dreamstation algo than they have on Resmed and that's only understandable, given that Respironics INVENTED CPAP therapy back in the 70s:, some 10 years before Resmed started as a company-)

I just posted a graph above that you should look at. Yes, with regular CPAP therapy provided for the treatment of OSA, it doesn't really matter because all you need is some positive air pressure to maint your upper airway open, so your machine algo does not need a breath by breath analysis, even though I personally think that it should, for efficiency and also comfort of the patient so they only receive positive pressure when their airway is open.

In the case of CSA treatment, the airway is always open , but the patient simply stops breathing (at times), so providing a "Continuous Pressure" is pointless . So the algorithm must monitor breathing and ONLY provide a breath when one is missing (a cessation of breathing lasting more than 10 seconds)...This is why ASV machines are used for the treatment of complex or CSA patients, so again I think that OSA patients too will benefit from ASV therapy just as much, in that they won't have to receive a "continuous Positive" pressure when their upper airway is open.

Anyway, all this means that I am better able to test a machine algorithm for efficacy, than I would be examining a regular CPAP machine that is always ON , providing a positive pressure.
