Respiration Noise - cam - 01-25-2013
Hello all.
I have used a Fisher Paykel 604 for the last 5 years. In spite of it falling off the night table twice when I first started using it, it remains perfectly functional. Extremely quiet, with no respiration noise whatsoever and the water chamber easily lasts over 10-12 hours without running empty. It has humidity and temperature controls.
I recently contacted the supplier for another slimmer unit and was given the Resmed S9 Autoset to try out. I find as does my wife, the respiration noise (inhale) is quite irritating as is the fact that the water chamber only seems to hold a fraction of the water that the 604 held and consequently after 6-8 hours of use the water level drops to within 1/2 inch of the bottom.
I love the slimmer, streamlined shape of the Resmed unit especially when travelling but I really do miss the 604. I am tempted to take it out of storage every night!
Is there a comparable unit out there?

For the inhale noise, make sure the filters are in correctly. Make sure the humidifier lid is firmly shut.
For the humidifier level, they've much improved how these things work. If I understand it correctly, it can detect the humidity level in the room and adjust the humidity to your mask based on that. In my winter dry house, I have little to no water left in the morning. In the summer, it's as if it was never on. You can experiment with turning the humidifier down to conserve water.
The next one to recommend would be the Respironics Pro Auto. I think that's the name. There's also the Icon but the software is not cheap. I think you can use SleepyHead with it, though.

Thanks Paula.
This is actually the second machine and both machines make the same respiration inhalation sound. The manufacturer and supplier say this is normal. I guess I am used to the FP 604. I thought perhaps someone could recommend another unit since this one is on loan to me to try it out.

Hi cam, welcome to the forum!
Here are important things to look for in a new machine:
http://www.apneaboard.com/wiki/index.php?title=Archangle:Machine_Choices
It seems many ResMed S9 AutoSets are a little noisy at some pressures and others are not. Some users are not bothered by the noise as long as the machine is placed lower than the bed (but on a low platform, or inside a box which has no top, so the machine's filter will not get dirty quickly from drawing air from too near the floor).
Take care,

I did make a recommendation. The PRS1 Auto and the Icon Auto.
RE: Respiration Noise - zonk - 01-26-2013
there,re more happy S9 Autoset users than other machines
many switch to S9 Autoset after tried other machines ... not the other way around
read the reviews, S9 Autoset is the most popular apap machine
if data is important to you, you cannot pass S9 Auotset
provide more data on machine screen including unintentional leak (only available on Resmed machines)
S9 Autoset supported by two readily available software, Resscan and SleepyHead

Hello All.
Well just returned both of my new Resmed S9's and picked up a PRS1 to give it a try and it's very quiet in comparison but doesn't seem to have the same volume of pressure at my recommended setting of 9. Also the outflow seems to be somewhat blocked and so I find I can't breathe out freely.
Not sure if there is something wrong with this unit but I intend to call the supplier tomorrow and ask. For the time being, I have switched back to my FP 604.

I can't think of any physical reason why this could be happening. The machine pretty much maintains the pressure of 9 cm regardless of the volume of air you inhale.

There's a feature called A-Flex that lowers the pressure when you exhale. The maximum setting is 3.

You must have a very understanding supplier!
Maybe the motors in these newer machines spin at a different frequency. You and your spouse may have adjusted to the pitch of the sound coming from the old machine and learned to "tune it out". Now you've got a machine putting out a sound with a different pitch and quality and it's annoying you. We have an air filter in our bedroom that puts out a white noise. It pretty much drowns out the noise from the CPAP machine. The only time I can hear it is sometimes when I first put the mask on. I figure I'm breathing at a faster rate, and as I relax in bed the breathing rate relaxes and the noise level drops. It may just be that it takes a few minutes for the brain to adjust to the noise and tune it out.
We're talking about a very low level of noise here, but it is audible.

The supplier thinks I should give it a couple of days. Perhaps it is just a matter of getting used to it. I've set the flex at 3 but they said if that doesn't work, just turn it off.
