Very bad idea. Start a thread stating what problems you are having. If you feel "out of breath a lot with my cpap", then your system may not be set up for optimal treatment. Members here (except xxyzz) can help you.

Subject: 130 infant deaths and 91 blindness cases. 1300 in study

By: Martha Garcia | Published: April 15th, 2013
Nearly two dozen universities failed to properly warn parents that a national oxygen study may put their premature infants at risk, federal officials say.
According to a letter (PDF) issued by the Department of Health and Human Services (DHHS) to the University of Alabama at Birmingham, the lead institution in the study, research institutions involved in the study did not offer informed consent to the parents of the premature infants.
The study involved 1,300 premature infants between 24 to 27 weeks of gestation. Researchers evaluated the results of increased or decreased oxygen through a continuous positive airway pressure (CPAP) treatment to determine the levels of oxygen saturation and neurological effects on premature infants.
According to the letter, the institutions involved were aware of the potential adverse affects the treatment may have on the infants, including blindness and even death. The DHHS Office of Human Research Protection says the institutions had sufficient evidence to know such treatment may cause serious consequences, but never properly informed parents participating in the study about the potential risks. The office considers the failing a violation of regulatory requirements for informed consent.
The study took place between 2004 and 2009 and 130 infants of 654 in the low oxygen level group died, while 91 of 509 infants in the high oxygen group developed a serious eye problem, which can result in blindness.
The study, published in the New England Journal of Medicine in 2010, was financed by the National Institutes of Health and involved 23 high profile Universities, such as Stanford, Duke and Yale.
The consent form only mentioned risks involving abrasion of the infants skin, and claimed there was a potential benefit of decreased need for eye surgery if the infant was assigned to a certain oxygen level group.
DHHS officials say the consent form should have highlighted that the risks of the trial were not the same as the risks of receiving standard care, so parents could make a more informed decision.

Wow, 2013, i hope they correct this before 2020. I'm not going to wear my child's mask until they do. Jim

first time post. 2 months on resmed 10. first 4 hours of use i was a different person, wide awake. sleep disturbed 186 per hour on side. 18 per minute on back. i set my tube temp to 70 and within a couple of weeks i noticed it wasnt cool air any more changed to 68 but no difference. also was getting tired all day and falling asleep. i had a cough the other night and about blew the mask off my face. i then realized it wasnt venting. even with hose off of machine plugged end of hose and could not exhale. vents would close. took it to the office and showed them what it was doing. tech hooked it all up and it was working as it should. last night it was working good for a few minutes. cool air and all. then warm air. not venting again. turned light on and observed humid air going up the tube re breathing my own breath again. note Ive been taking mask off in my sleep then putting it back on and resetting machine. please take note you should not be getting that warm air while using machine. lucky to still be alive.

Welcome to the forum and to CPAP! You've posted at the bottom of a thread that's several years old - you'll more likely get advice/help if you start a new thread. Also, it's helpful to those offering advice if you fill out your equipment profile (go to User Control Panel in the top left corner of the page).

My own comment would be that if your bedroom is cool at night, and you've set your tube temp at 70 (or 68), you're asking the machine to heat the air for you. Personally, I leave the heat turned off, as I prefer to breathe air the same temperature as the room.

Did you soak it when you got it? I soak new mask parts for at least 60 mins in soapy water (I use Dawn). Then, spray with white vinegar and let sit for 3-5 mins, rinse very well, air dry. There should be NO smell.
