how does a paper bag help hyperventilation?
397876
Hyperventilation is when you breath so much that you blow off too much CO2 and your bloods partial pressure of O2 goes up (not because you have too much O2, but because you've removed/blown off too much CO2).  It is usually caused by anxiety, fever and aspirin poisoning (Sherwood, 1997).  CO2 is an important buffer in the blood and is needed to maintain the internal pH around 7.4.  Blowing off CO2 leads to respiratory alkadosis (blood is too basic; Sherwood, 1997).  Breathing into a bag forces you to re-inhale the CO2 you've blown off so that the carbon dioxide levels in your body do not fall off too much (or that's the theory anyways).

this is supposed to work for the respiratory system.\n\n1. cut of the top part of a large  plastic soft drink bottle right above where the label starts. don't throw away the cap/cover.\n\n2. punch a hole in the cap/cover.\n\n3.get tubing or connect straws in such a matter that it forms a Y. make sure if u are connecting straws to seal any gaps.u can use rubber cement to seal it.\n\n3. push the tail of the Y through the bottle cover (while it is on the bottle) that u made a hole in. seal it well so no air can get in easily.\n\n4.get  2 small balloons and use rubber bands to fasten them to the branches of the Y, 1 for each branch.\n\n5. to complete the project, get plastic wrap and use it to cover the bottom of the model(the open part of the plastic bottle where u cut). use masking tape to fasten it.\n\nif it is done correctly, when u blow through the straw poking out of the bottle cover the balloons will expand and then deflate.\nThe balloons are the lungs, the tubing the bronchii, the plastic wrap the diaphragm and the bottle the lungs.I hope this explanation helps;i tried to make it as clear as possible.

Air pressure and density. Sort of like when you fly, your ears pop.\nAs you get higher, air pressure and density are lower, than on normal ground level. This less pressure caused stress to build up in the bag as the air in the bag has more density than the air surrounding it.

This is the only real way to instantly cure the hiccups! Look no further!  The Hughes/Green method cure's the hiccups EVERY time GUARANTEED!  You will be amazed!  Hundreds of instantly cured hiccuper's have sent in their testimony's of deliverance! Files are available for researchers! Carefully understand both the HOW and the WHY of this method. If you don't get the WHY you might not get the HOW. Here's how to cure the hiccups:\n\n"Hughes/Green Hiccups Cure"© 1997\n\n(1) Pour a TALL glass of water.\n\n(2) Hold your breath... ***\n\n(3) IMPORTANT...PINCH YOUR NOSE CLOSED.\n\n(4) Slowly, take 10 - 20 swallows of the water...while holding your breath with your nose pinched closed.\n\n(5) When you can't stand it any more....you'll know by that overwhelming drowning sensation -- after a gasp, take a deep breath and relax.\n\nThis cures the hiccups 99 percent of the time - guaranteed! It's a proven medical remedy! (A second treatment could be necessary for stubborn cases.)\n\n*** For stubborn cases, try EXHALING COMPLETELY and then taking 10 - 20 swallows.\n\n      NOW: HERE'S WHY IT WORKS: Hiccups are caused by an uncontrollable spasm in the diaphragm, (the "breathing" muscle). Often, this spasm is triggered by irritable conditions in the smooth muscles of the stomach or the esophagus. The "Hughes/Green Hiccups Cure" forces an increase in the carbon dioxide levels in the diaphragm itself, as well as in the stomach and esophagus. By swallowing, you are making the muscles work -- so they use up their available oxygen and replace it with carbon dioxide. By temporarily discontinuing to breath, you prohibit new oxygen from entering your body and thus create an anaerobic condition in the spasming diaphragm muscle. When the spasming diaphragm and stomach are deprived temporarily of oxygen and encounter the higher levels of carbon dioxide ... you feel that scary drowning sensation! BUT this causes the spasming muscles to relax! The hiccups go away! Essentially, you are "tricking" your body into thinking that it's drowning ... and it decides to use it's resources for something other than hiccuping. The rather "scary" drowning sensation caused by this method is NECESSARY for the method to work. If it's not just a little bit difficult ... it doesn't work.

you should try aerobic exercise...\nAerobic Exercise\nAerobic exercise provides cardiovascular conditioning. It strengthens the heart and lungs, and improves the body's ability to use oxygen. Over time, aerobic exercise can help decrease your heart rate and blood pressure, and improve your breathing (since your heart won't have to work as hard during exercise).\n\n\nExamples are:-\nJogging \nRowing \nSkating \nCycling (stationary or outdoor cycling) \nSwimming \nWalking \nCross-country skiing \nAerobic dancing

Suck in as much air as you possibly can - so much that it prevents the hiccup spasm occuring - and hold it as long as you can.  Simple, effective.

Hiccups are a spasm of the diaphram.  Hold your breath and while doing so, take your middle knuckle and hold it against your windpipe.  This keeps any air from getting through.  It has always worked for me.  It's probably the same principle as people telling you to try and drink water while you are holding your breath, however I think it's more effective than drinking water, because you aren't allowing any air to get in.

I had anxiety problems once in awhile and I just told a doctor. He gave me medication for any time the feeling accured. I also learned that when I had anxiety attacks, which wasnt often, to breathe in a paper bag for awhile. The carbon dioxide you breathe in, with less oxyagen in you system calms you down. Hope I helped you out. advise, see a doctor for sure.

If you are hyperventilating or have eratic breathing, it would help control that as you can't breathe and swallow at the same time. (If you do you'll drown).

Which activity is the best exercise for increasing heart rate?  Scootering, walking, running, skating?  \n\nWhich material is best for protecting something fragile? Take potato chips and wrap them different ways - bubble wrap, packing peanuts, etc.  Mail them to yourself.  Which ones are intact?  Take pictures before, during wrapping, and after you receive them.\n\nAlso, check www.dicovery.com.  It's the discovery channel web site and they have a lot of ideas.  \n\nThe show Mythbusters can also give you some ideas, but be careful, some of them should only be done by professionals.  You might be able to take one of their ideas and modify it, though.\n\nGood luck!

People tend to hyperventilate (breathe fast, without giving the body time to process the air exchange) when stressed.  This causes low levels of carbon dioxide in your blood.  In the past, the remedy was to breathe into a paper bag, thus reducing the amount of oxygen you were taking in and increasing the CO2.  Breathing through a paper bag is NO LONGER RECOMMENDED because this can quickly lead to too much carbon dioxide in your blood stream. \n\nNowadays, to increase your carbon dioxide, you need to take in less oxygen. To accomplish this, you can breath through pursed lips (as if you are blowing out a candle) or you can cover your mouth and one nostril, breathing through the other nostril.

called a rebreather and it circulates your air and scrubbs it clean so you have air to breathe , closed loop system. its a large backpack thing and it requires special training. james bond thing is cool but non existent.

Breath in very slowly\nTake as much air as your lungs will hold.\nHold this air for as long as you can.\nRelease the air slowly.\n\nYou will find that you will calm down with the breathing exercise.  While simple, it really does work.\n\nHave a lovely rest of the day.
