A Better Heated Hose? HC604

Post by Maskedmechanic » Thu Jul 28, 2005 6:09 pm

Looks like someone is listening to the many conversations here about heated humidification and heated hoses. Here is the link to a new cpap with a computer controlled heater plate and heated hose. https://www.cpap.com/productpage/fisher ... -cpap.html

I have the Fisher Paykel HC221 LE. I wonder if the heated hose would work on it. It looks a lot like the unit I have. Probably not. They probably made it where you have to buy a new machine to get the hose to work. They could make a lot more money that way!!!!!!

I doubt if the F&P HC 604 has a "better" heated hose than the Aussie heated hose which, thankfully, can be used with all kinds of machines.

That is a nice step in the right direction, though, for a cpap manufacturer to include a heated hose with one of their machines. Too bad they didn't just produce a heated hose a la the Aussie one...to be used with any machine. Or maybe that hose can be?

Mechanic, can the hose be bought separately and used with other brands of machines? Or does the hose itself have to get instructions from the computer heater plate?

Wonder if F&P realized they don't really need a "computer driven heater plate" with a heated hose. More of their "ambient tracking" idea, I suppose.

tater pie, I think you nailed it - probably got to buy that particular F&P machine to use their heated hose. I'll stick with the tried and true, Aussie heated hose that doesn't limit me to one machine - and a straight F&P cpap, at that!

The computer controls the function of the heated plate and the heated hose depending on flow and room temperature. During a mouth leak event for example, the heater plate would be getting maximum power to get am much humidity into the system as possible and the hose power would be low since the time the air has in the hose is low due to the high flow. If there is no mouth leak and the room cools, the hose gets more heat to keep things from cooling down. This is much more sophisticated that you are thinking. Basically the system is told by the patient the highest temperature air they are comfortable with. The machine then provides the highest absolute humidity it can, using computer control of the heated plate and heated hose, with zero rainout regardless of room temperature changes. Nothing available now can do this.

Older Fisher Paykel systems can not be upgraded to include this technology. This is a totally redesigned unit.

The hose is not made for use with anything other that the HC604. There is no stand alone kit of any sort coming out anytime soon as far as I know.

Wish I could do a better job of explaining this. I need to learn a lot more. I understand there are clinical studies that demonstrate that cpap, even cpap with heated humidifiers can dry out the sinus enough restrict air passage through it. Fisher & Paykel has some of these on their site I think. When this occurs, the cpap pressure is reduced below the blockage and sleep disordered breathing occurs even with cpap. Patients then open their mouths, the flow from the cpap increases since the air can just zip out the mouth, causing the sinus to block up even more and the result is obviously a seriously compromised therapy. Occasional mouth leak is very common (almost all cpap patients have mouth leak occasionally).

Thanks for a wonderfully clear explanation, Mechanic.

Will be interesting to see if this really works as planned should there be a long leak session of heated humidifier's water temp high and hose temp low.

Occam's Razor comes to mind.

Many years ago I worked for a subsidiary company of F&P, I used to know Gary Paykel himself (son of one of F&P's founders, Maurice). I once owned a house on a residential estate in a place called Pakaranga - this whole residential estate was once part of Gary Paykel's family home (now the Paykel house just occupies a small half acre or so on the top of the hill in the middle of the estate )

(Gary has put on a bit of weight since I saw him last - but so have I )

Great company that has grown & grown. Started of in NZ grew into the Australian market & now establishing a presence in USA & other countries.

The were always a 'quality' company plus were driven by innovation. However a few folk in the Sleep Studies Clinic I am involved with, feel that F&P were a bit slow to listen to suggestions although the new 604 looks like one very smart machine.

I hope to try it out soon.

Hmmmm time give me ole mate Gary a call - I can just see it now - ring ring, ring ring, "Hello Gary Paykel speaking", Hi Gary ow are ya goin mate ? - "Who is that ?", its me yer ole mate Doug from MEC, "Doug who ???" ......
