Heated humidifiers and bacteria

Humidification in CPAP Therapy
The following information is provided by Fisher & Paykel Healthcare

Frequently Asked Questions
Q. Is it possible for a patient to catch an infection from a humidifier?
A. The environment in the heated humidifier chamber under most operating conditions is such that the majority of pathogens are rapidly killed.

Even if pathogens were able to exist in the humidification chamber, they would not be able to be transported to the patient. The humidity travels from the chamber in vapor form, which is too small for a bacteria or virus to travel in.

Relative Cell Sizes of Bacteria, Virus, and Water Molecules

Q. Will treatment with nasal steroids prevent nasal symptoms from occurring?
A. Nasal steroids assist in the prevention of allergy induced histamine reactions in the nasal airway.

They do not alter the clinical nasal response to cold dry air (10). Heated humidifiers heat and humidify the air so that airways can be maintained under optimum conditions and are not adversely affected by the increased flows of CPAP therapy.

Q. How can the sleep lab maximize patient comfort and minimize nasal symptoms during titration?
A. Using heated humidity will maximize patient comfort and minimize nasal symptoms during titration. Heated humidity can easily be used during titration by including a heated humidifier in-line with the titration system.

Q. Do patients who live in a very humid environment still need a heated humidifier for CPAP system?
A. Often people who live in a humid environment will have air conditioning systems and dehumidifiers operating, so the air which is passing through their CPAP system is cold and dry. This causes an increase in the occurrence of nasal symptoms and may result in patient discomfort.

Exactly! That's why I'm more comfortable with my h/h and if I turn it down too low (like last night) my throat is irritated.

BTW Gary, why do you make your text so big and green?

I type big and green because the default type is so tiny I can't read it.

Gary, on the top of the page you have a row of buttons that can help you change the default size to a size you can read better.

this is normall and green. See what it looks like when you chage font sizes.

Yes, that does make everything bigger EXCEPT for the text that people write. Any other ideas to get that text bigger?

Thanks,
Gary

Hold down the CTRL key, and roll the wheel on your mouse.

If you don't have a wheel on your mouse, go to VIEW up in the menu bar, and under TEXT click on larger and then go spend 10 dollars for a mouse with a wheel. Cheap and very easy to use. Best option I know of.

I tried the mouse wheel technique and that works for some text on some sites. Unfortunately, it does not work for the text here. I would be curious to see if it works on this site with your mouse wheel or VIEW then TEXT SIZE. Oh well, guess I will have to just be like the jolly green giant and be big and green!

Ctrl + spinning the mouse wheel works on this site for me to make text bigger/smaller. I'm using Firefox as my web browser.

The mouse wheel trick doesn't work for me if I use IE to look at this site. Actually, I don't use IE for anything anymore, except one or two sites that won't work right with anything but IE.

RG -

Mouse wheel works for me, too. Using Firefox for the internet, and IE for obsolete sites .

Just for the record, I like your large, green letters...for once, I can actually read a post without leaning forward to my monitor LOLOL (I have ooollllld 51 year old eyes)

I also tried rolling the wheel and it didn't work..I have no problem in other websites with that...strange it doesn't work here*shrug*

RG, not only are you an expert on matters CPAP but you have just impressed me that you have FireFox as well - now that is smart on smart

PS all you others here who use FireFox, take a bow. I heard that Microsoft are so alarmed at the stampede of browsing folk to FireFox, that they will incorporate its best ideas in their next 'Longhorn' version of MSIE.

I do admire the way MS supports the clever little guys beavering away in their garages (yes I was being sarcastic about MS, please excuse me )

Anyone wanting a great browser with some outstanding features & anti pop-up anti-spyware features just google firefox.

Cheers

DSM

rested gal & dsm,

Totally off the subject of this board but I have a problem with the Firefox browser. I used it for a long time until recently. I decided to d/l a new theme, it did not load correctly and has now made the browser unusuable. I have tried uninstall/reinstall but I always get the same messed up version. How can I get rid of this and get it to load correctly?

Hope you can help.
