"If the heated tube works with your machine I would try that.  They also make covers for your tubing which may help some.  I think the heated tube may be your answer.  Keep us posted."

Non-invasion approach that can relieve mild sleep apnea

Some people report that singing -- singing! -- really helps their sleep apnea. Dr. Stephen Park said that myology (which are exercises to strengthen muscles around the inside of one's mouth area) helps some. I think singing would be better.  If you read all the FAQs on this (click below), I think you'll agree that it makes sense for some. Maybe you.http://www.singingforsnorers.com/index.htmSee More

CPAP pressure vs. the air that escapes from the front of the mask

One of the downsides to my CPAP therapy is that whenever I face the middle of the bed, I have to block the front of my mask becuase the air that blows from the holes above my nose bugs my wife. So, my question, is if my machine is set at 13, am I really getting this much pressure, since there seems to be alot of air coming out of the front of the mask? I am guessing the reason this air blows from the front of the mask is to deal with carbon dioxide that we all exhale, but, does this air escape affect the pressure setting and the level of therapy provided by CPAP? I'm not talking about mask leaks, but, this is the air that escapes thru the holes that are naturally in the mask when it was produced. Thanks,

to rephrase your question, you're asking whether any of the prescribed pressure "leaks" on inhalation, not on exhalation, which we all know to occur, and if it doesn't leak on inhalation, why not because there are holes there? I'm fairly sure that none of the air leaks on inhalation, just on exhalation, so that if you're prescribed 13 cm of water pressure you do in fact get delivered 13 cm of water pressure, but we'll see what the pros have to say.
Not sure how the end user product flow rate works, but in the lab at 13cmwp our machines fluctuate from abou 12.5 to 13.1cmwp. I could not imagine a true consistancy in any type of airflow. too many parameters. Hose length, does it have a bend or a kink in it, type of mask, type of cpap unit. The machines job is to keep you as tuned into your sleep number as it possibly can. I think for the most part they do this well. As for the air vent in front of your mask, I would not advise covering it. This is for co2 to escape during exhalation. This will for one cause laeks in your mask by making it rise of off your face. also we would not want you to suffocate. Not a major worry but it could happen as the high amounts of co2 could cause problems.
The pressure largely depends on wheter the machine has leak compensation. If it does then it should adapt to medium leak amounts. The mask problem can usually be overcome by changing the mask to a mask that vents not directly forward. The mask should leak at around 24l per minute by itself.
The air that leaks out of nthe front of the mask. It's supposed to...1.) as a vent. To get rid of the nasty bi-products of resperation. 2.) if the power goes off you'll have some way to breathe until you wake up, and take off your mask.
I agree with the chorus. There is a continuous leak, during both inhalation & exhalation, that is compensated for by the flow generator.
So it's supposed to do that? I hadn't noticed it at first, but in the last week, it seems to have suddenly appeared? Could be just me not noticing until recently. Is it supposed to come out around the plastic tube that the longer tubing connects to?
yes all mask's have vents, of some kind.

Oh my gosh I have been dizzy for several weeks since I got my new mask. From this forum I think I just figured out that I covered the exhale hole when I got it and now have too much C02 in my system!!! No one ever told me not to cover that hole or what is was for.....yikes....
Thank you so much for this info, you really helped me out as I had no idea what that hole was for and I have been light headed for weeks!!! You would think the doctor or med equipment people would tell you this stuff....

I would expect the pros to be less than enthusiastic on the idea of water pressure..... ;-)

Besides the practical reasons for the vents, I'm glad they are there, sometimes I put my hand in front of my mask to make sure the machine is on, otherwise I'm not sure if it is. My husband has noticed the "breeze" too - I don't think it bothered him though.
