PRS1 60 series humidifier not working well **Update**

Post by RandyJ » Fri Jan 30, 2015 12:28 pm

I switched from a Resmed S9 to a PRS1 Pro 560 (with heated hose) back in August 2014. All went fine until early December, when I started awakening during the night with swollen nasal passages, feeling like I was breathing through a straw. I switched from nasal pillows to my nasal mask, which seemed like it gave more air flow and I breathed better. After a few weeks, I noticed that I had blood (dried and fresh) in both nostrils most of the time.

I also noticed that compared to my S9, the PRS1 humidifier was using a LOT less water. With my S9 I would refill the water chamber every other day. The PRS1 seemed to go at least 4 days on a fill. So I concluded that I was getting less humidity, even with settings on maximum (3 for humidifier and 4 or 5 for temperature). After about a month of this, it became common to wake up during the night with breathing issues, one or both nostrils closed.

I talked to my ENT and he recommended Ayr Nasal Gel several times a day, which helped, but eventually he suggested having the machine/humidifier checked out, so it's at the DME now. While they have it I've been back on my S9 which is putting out all the humidity I need, and my nasal passages are getting better. No more blood, but still some issues with closing up. I considered going back to daily nasal irrigation, and may still do that, even though Dr cautioned me about using too much saline and aggravating the dryness.

I'm hoping to hear from DME that they found a problem with my machine and/or humidifier, but I'm not optimistic.

Does anyone know if this is a known issue with the 60 series humidifiers? Do people find that humidity is not what you'd expect at the highest setting?

Thanks....

Randy you might want to take a look at this thread, I believe I read somewhere the 60 could have same problem. viewtopic.php?f=1&t=102275&p=959965&hil ... ir#p959965

Did you by chance think to change the machine over to Classic mode at a setting of 5? This would eliminate ambient humidity being high as a possible culprit in the lack of delivering the moisture.

Personally...I doubt that Classic mode would change anything and I think that probably something is going on with the humidifier or hose (sensors at the hose) but would at least rule out a potential factor.

Humidifier failure isn't common for the 60 series unit but not totally unheard of.
Neither would be a possible problem with the sensor at the mask end of the heated hose....not common but not impossible either.

There are settings in both the user and clinician menus that affect humidifier operation. Once the machine is on, you should be able to turn the control dial from 1-5 for humidity settings. I keep the humidifier on 3, and the heated hose on 2. If I increase humidity to 4, the tank will nearly dry out in 9-hours.

The heated hose connects to the humidifier with a plug in the back-left of the humidifier base. You will only see the plug with the lid off. The lid lifts up and forward to detach. If that was disconnected, then the settings would not be right for the heated hose diameter, and heat. Checking connections, and verifying on the menus the heated hose is detected and configured properly is the first check. If the 15 mm hose is not automatically selected, check the connections.

Secondly, you can put the humidifier into preheat mode by holding the control dial down 4 seconds. The amber wavey light should come on. Let it work for a few minutes, then pull the water tray and feel the heat transfer disk...it should be warm. If not, then there may be a fault in the humidifier.

My PRS1 60, the only machine I have used since I started this therapy a year ago, in the winter uses up most of the tank every night, which means I use a gallon every 6-8 days, depending on the weather. Here in Minnesota, the air is very dry in winter, and quite humid in the summer, so over the summer I needed less than half a tank each night.

Last winter was a brutal winter, and the air was so dry that the tank ran completely dry nearly every night... this winter, only runs nearly dry, but there's a lot of winter left, and it could get just as brutal. I have nothing to compare the PRS1 60 to, so I don't know anything about the differences.

Provided the problem is not due to your settings - if you received a new machine in August it should still be under warranty so insist on getting it fixed to your satisfaction especially if you say it isn't using much water per night.

Good luck.

I did think of this but didn't do it. I've never switched out the humidifier cover and was afraid to break it, but I had the guy at DME demonstrate removing it for me.

When I get it back, if I"m not happy with humidiity output with heated hose I'll switch out the cover and use with regular hose in Classic mode.

Thanks, all. I'm convinced that something is not working properly, whether it's the machine's humidistat which isn't properly assessing the ambient humidity or some other reason, but it is definitely using very little water even at highest setting, so... I'll update this thread when it gets figured out.

Randy

I have both machines also. I found it almost possible to empty the water chamber in one night with the 60. The resmed chamber holds much more water. Is the heat pad on your machine getting hot at all?

Its sad to hear about the problems with the PR One's. Mine came in a box with made in America on it

I had to return my 60 to cpap.com who confirmed my blower was faulty (noisey) and they replaced it with a new one. cpap.com paid the shipping both ways too, excellent service.

Good luck

I haven't tried Classic mode with my 60 series machine but you don't need to change the lid to use a regular hose that I am sure and you may not even need to change the hose to try Classic mode. I haven't tried that part of the heated hose to see if it would allow Classic Mode with heated hose attached.

Last summer I switched out the heated hose to a regular hose on my 760 because I was going camping and was unsure how much power I would have and knew that the heated hose was a drain...regular hose worked fine on the heated hose lid.

Bob,

Thanks. I loved my Resmed machines, but with new insurance I was eligible for a new machine, and I wanted to try out the PRS1 60 series w/heated hose. It seems like a nice machine, and I like the fact that it's made in America.

The humidifier warmer plate DOES heat up, but it's putting out very little moisture through the hose, so there must be some other problem. I hope they can fix it and don't give it back to me and try to tell me there's nothing wrong with it.

Take care,


Randy

It's true you can attach a regular hose to the heated hose cover, but I wasn't sure if the machine would run properly. They gave me both covers when I got the machine, so I just figured you needed to change them out if you wanted to use a normal non-heated hose. There is also that little wire that runs under the cover and connects below. I was really afraid I'd break something.

You don't need to change out the covers. I use both hoses on the heated hose top.
I only have the heated hose top and wonder where they got the regular cover unless they took one that wasn't with a heated hose cover and added the heated hose kit.

Last week there was a power outage around 11:30pm to 2am and my grandfather woke up and couldn’t go back to sleep. I did some research to avoid the same situation and bought a product called Pilot 24. Apparantly its a back-up power supply specifically designed for power outages. Luckily there were no more power outages since last week to try it out but we did use it as a travel battery and it lasted 2 nights. Not bad
