    Oxygen will not run out while you're on an airplane. The issue isn't so much running out of oxygen as it is not enough pressure at altitude (Not only do your lungs need oxygen, they need pressure to force the oxygen into your blood). You are able to breathe on an airplane while it's at cruise altitude because the engines compress air from outside increasing it's pressure and that air gets pumped into the cabin at the pressure needed to be comfortably breathe. The cabin is sealed and the air is regulated by a valve, usually at the very back of the airplane. So provided that there are no big holes in the cabin (windows blowing out for example), the airplane will maintain pressure. So there is a constant supply of air that will not run out for the people on the airplane.

    If there were a problem and decompression and you had to use the oxygen masks that drop down, there's about 15 to 20 minutes of oxygen with those masks. If the masks do come down the pilots will be descending the airplane to an altitude that you will be able to safely breathe.

    Your doctor won't call CPS because they are under privacy acts to not share your personal info. with anyone. Unless you were abusing the child. I don't think that this is normal to this extreme. I have an 11 month old and a 3 week old colicky baby who cries all night, and I just keep thinking "it will get better" I don't imagine giving them away or running away. I do wish that grandma would take them once in a while so I could get some sleep. But that's as far as it goes. I like being a parent but there are times when I think that I should have waited longer. I think you need to talk to a professional. And perhaps giving this baby up for adoption would be the right course of action if you really think that she/he would have a better life and that you can't handle being a parent & don't see yourself changing. Of course there is the father's say in the matter. I hope you watch this because it only takes 5 seconds to shake a baby to death or brain damage, and it can happen so fast that you don't even know what you're doing until it is too late. Think about it, would you rather have a parent that does not want you, or be given up for adoption to a family that wants nothing more than for you to be a part of their lives? If you really do not want this baby, give her up for adoption. The sooner the better. Good Luck.

    Airplanes never leave the atmosphere, therefore there is always oxygen available. At 30,000 feet, the amount of free oxygen is less than at sea level, the planes use supplemental enrichment systems to keep the O2 level at about 20.5%. The amount of available oxygen outside the plane is more than adequate to keep the engines burning, and is sufficient to support life, although not ideal.
