G'day I'm in Toowoomba Qld and use a Puritan Bennett GoodKnight 420E with a DeVilbiss 9100D heated humidifer, a SleepZone heated hose and a Resmed Ultra Mirage Full Face Mask. I also use the Puritan Bennett Silverlining 3 software. I got my first machine in April 2004 and had it replaced under (exte...

My 420E broke off at the sensor nipple in June last year when it was well out of warranty. The agent in Australia eventually replaced the machine after about 2 months of argy bargy. I had to hire a Respironics Remstar auto M series for the 2 months and was interested to find that the 420Es gave much...

Yesterday I gave figures for my new PB 420E for comparison with my old one and with a rented Respironics M-Series with C-Flex. I sad: "With my new 420E, over the first 19 days (after which I got a cold), my 90% pressure was 7.0, average pressure was 6.2, overall AHI was 0.2 and average acoustic vibr...

I just came across where Kajun said in answer to 4 easy questions: "2) How many machines have you owned? 2, my original PB 420E and a replacement generously provided through our hosts here when my original broke (the hook-up nipple for my sensor tube snapped)." I had my original 420E from April 2004...

When I started on CPAP, I bought a Puritan Bennett GK 420E. At that time PB didn't make a humidifier for it, so I got Devilbiss (9100D) with heater (9200) - they come sparately for people who just want a passover humidifier. It must be one of the most efficient humidifiers around, because the air ha...

Thanks for the reference to the original paper. The 41 "normal" subjects were in fact a control group for a different study altogether. The rough and ready way they were selected may have been OK for that study which focussed on 110 mild-moderate sleep apnea patients. It's another matter to treat th...

The reason why we classify normal as being <15 is due to a study our lab ran which looked at what normal was in a group of asymptomatic normal subjects. This is also at the bottom of our sleep reports Normative data: In an Australian study1 of randomly-selected asymptomatic normal subjects aged 30 ...

I'm a bit surprised at this. Do you have a source?
Anything I've seen in Aus goes with <5 = within normal limits; 5-15 = mild; 16-30 = moderate; 30+ = severe.

Thanks for posting these articles dsm. The RSNH study should be compulsory reading for all sleep clinics! I had no idea I had sleep apnoea. My wife used to complain about my snoring, but I didn't really believe her - I never heard it! When we moved to a larger town in 2002 and started with a new GP,...

I've had good success with my Devilbiss 9100/9200. I use it with a PB420E auto. See https://www.cpap.com/productpage/1306 It has a large surface area and makes the air go up and back four times on the way out. You can get just the humidifier as a passover unit, or you can also get the heater base. N...

As noted in previous posts, I can run a 420E with a "piggy-backed" heated hose no problems with a Powertec MP3240 power supply rated at 100 to 240V input and 12V 4A output that came with my 420E purchased in Australia. That power supply would work quite happily in the US too. It's made in China so t...

I'm another lucky one. I use a PB420E and have found no systematic relationship between the amount of alcohol consumed and either average pressure or AHI.

I'm 67. Been using my 420E for 18 months.

I use a PB420E with Ultra Mirage Full Face Mask no problems.

I bought a Xantrex power supply similar to the one described at the following site: http://www.xantrex.com/web/id/61/p/1/pt/5/product.asp Haven't had to use it yet. My PB 420E should go for two or three nights on it if necessary - without heater. Heater uses too much juice and apparently the electro...
