lungs collapse and people recover right? how does the structure that collapsed build back up...why do they collapse in the first place/ what does it really mean when your lungs collapse?

First of all, when you think of lung collapse it isn't the entire organ that collapses. There are tiny air sacs in the lung called Alveloi. There are numbers of these alveloi in your lung. Everybody has some of these air sacs collapsed all the time. It is very small and doesn't effect everyday life.\n\nThere are many reasons that can cause the lung to collapse. Trauma, post surgery, pneumonia or other pulmonary infections, masses or tumors, air or fluid between the chest wall and the lung. \n\nThe reason that they can 'build back up' is that the alveloi are like balloons. If you can get air back into the air sacs with breathing exercises and other measures then they open back up.\n\nHope this helps

Sounds like the doc said, an inflamation, maybe caused by an infection.  I've had it a few times, but normally following a rib injury, which does not have to be major. You don't breathe properly, or cough, so the air in the bottom of the lungs gets stagnant.

Its takes a while to be yourself again.  Some people are doing great within weeks while others take months.  A lot depends on pain tolerance and willingness to do rehab and exercises as ordered.  If you do not do your rehab it will take much longer and your are much more likely to develop complications such as pneumonia.  It would be very helpful to have someone around for a few weeks to assist you.

I would contact your doctor who handled your case, spontaneous pneumothorax once makes you more likely for another.  But there is no way to eliminate your chances, I have seen folks come into the ER for a cough, a sneeze, and then others have no reason or way they know it could have happened.  I have seen repeated visits from folks who have problems.  I again would contact your doctor and see what he or she would like you to do.  They might have something they wish for you to do in order to fly, or swim or they might advise against it.

I'm going with B on this one.  The pulmonay arteries are taking deoxygenated blood away from the heart to the lungs to pick up O2 and drop off CO2.  This would mean that this blood is as full of CO2 as it can be in the body - at least in healthy people.\n\nC, the pulmonary arteries have just dropped off their CO2, so they don't have much. Not it.\n\nD, I think if the PCO2 were higher here than in the blood, then CO2 would diffuse out of the lungs and into the blood. Not it.\n\nE, The CO2 from the interstitial fluid is always diffusing into the veinous blood.  It's kept at a fairly constant rate, so that's probably not it.\n\nA, this could be the answer.  Honestly I don't know the PCO2 of the atmospheric air, but it would make sense to me that it's lower than what's in the pulmonary arteries because, again, CO2 that you breathed in would diffuse INTO the blood instead of out of it.

YES!  \nAbsolutely it does!\nYou are not taking in the proper amount of oxygen therefore not oxygenating your blood stream/muscles/lungs properly.

When you're breathing hard you're using your lungs, and your heart is pumping big time.  Be sure to not stop all of a sudden, but cool down eventually so your heart can slow down slowly.

Chest pains are NEVER something to fool around with. Do you have any idea how many people end up dying from heart attacks because they thing it is indigestion, just like you think, and they delay going to get medical help! Also, did you know that the symptoms of heart attacks in women are much more subtle than those in men? If you are waiting to fall over, it probably won't happen until it is too late. People of ANY age can have heart attacks. If you are overweight, your chances are higher than the general population. People also have mini-strokes and heart attacks that don't kill them, called silent heart attacks, but part of the heart muscle is permanently killed. Is it worth fooling around with the whole rest of your life. You would not take out your own tonsils or let one of us take out your tonsils, but with something as serious as your very life, you are asking rank amateurs. Please go get checked out. Better to be safe than dead.

You can't hold your breath for that long because the brain will eventually take over and make you start breathing again. It's a survival instinct built in as a safety net.

The Lungs are made up of millions of tiny air sacs called alveoli. These alveoli are like the millions of little holes in a sponge.\n\nJust out of curiosity, did you feel them in a dissection or something?

The best thing you could do in a situation like that is to report it to the one in charge of management in the hospital. I'm sure thy would love to know who they hired on. You may save someone's life in the process. You never know?  Let me know what happens. God bless.  :) Oh, and my niece had a problem with her lung collapsing and they gave her oxygen pressurized into her lungs every so often to open the lung back up. Only because she couldn't do the regular breathing treatments.

like all natural things there is a resource of oxygen stored in our boby in form of water... if the body is short of oxygen the body tries to convert water into oxygen thus stop from dieing... \n\nwhen you hold your breath initially there is a shortage of air in the body you get unconscious during this period the body starts to convert some amount of water into oxygen... and waits for our body to get external air... \n\nthis is a slow process and if your body is not strong enough to resist... then you can even die immediately...

There are many blood vessels in the lungs, but if they burst, they seal up immediately because they are so small.  You will be fine, but you should still see a doctor because a doctor will know more than me.

That happens to me too, after I make any sudden movements. I don't think you're going to drop dead from a heart attack any second now, but I do think if you don't do something about it it could lead to heart/chest problems later in life. I'm assuming it's your heart, unless you have a broken upper rib right in the middle of your chest. It's good that you've gone to a doctor to check things out, because you're better safe than sorry. If looking to be on the safe side, you should probably just drink lots of water and eat bananas or something because water flushes all of the bad toxins out of your body.

Dr. Barry Make, a pulmonologist at National Jewish Medical and Research Center in Denver, says the answer is not because we are tired or bored — although that’s the common perception. Read on for his explanation.\n\nThe most plausible explanation, and the one that is taught in medical school, is that we yawn because oxygen levels in our lungs are low.\n\nTHE TRUTH IS that we don’t completely understand why people, or animals for that matter, yawn. It’s widely assumed that yawning occurs because we are tired or bored or because we see someone else doing it, but there isn’t any hard evidence to support these beliefs.\n\nThe most plausible explanation, and the one that is taught in medical school, is that we yawn because oxygen levels in our lungs are low. Studies have shown that during normal, at-rest breathing, we don’t use anywhere near our lung capacity; for the most part, we just use the air sacs at the bottom of the lungs. If the air sacs, called alveoli, don’t get fresh air, they partially collapse and the lungs stiffen a bit. As a result, it’s believed, our brain prompts the body to either sigh or take a yawn to get more air into the lungs.\n\nBut certain aspects of yawning remain even more mysterious. Fetuses, for instances, have been observed yawning in the womb, yet it’s known that they don’t take oxygen in through their lungs. And yawning seems to be a symptom of multiple sclerosis and other medical conditions, for reasons unclear.\n\nAnother puzzling phenomenon is that some male animals, men included, yawn in association with penile erection (although it’s presumptuous to assume they’re bored with their sex lives).\n\nNext time you're in a meeting, try this little experiment: Take a big yawn, cover your mouth out of courtesy, and watch and see how many people yawn. There's a good chance that you'll set off a chain reaction of yawns. Before you finish reading this question of the day, it's likely that you will yawn at least once. Don't misunderstand, we aren't intending to bore you, but just reading about yawning will make you yawn, just as seeing or hearing someone else yawn makes us yawn. \n\nInteresting Yawning Facts\n•The average yawn lasts about six seconds. \n•Your heart rate can rise as much as 30 percent during a yawn. \n•55 percent of people will yawn within five minutes of seeing someone else yawn. \n•Blind people yawn more after hearing an audio tape of people yawning. \n•Reading about yawning will make you yawn. \n•Olympic athletes often yawn before competition. \n\nWhat's behind this mysterious epidemic of yawning? First, let's look at what a yawn is. Yawning is an involuntary action that causes us to open our mouths wide and breathe in deeply. We know it's involuntary because we do it even before we are born. Research shows that 11-week-old fetuses yawn. \n\nThere are many parts of the body that are in action when you yawn. First, your mouth opens and jaw drops, allowing as much air to be taken in as possible. When you inhale, the air taken in is filling your lungs. Your abdominal muscles flex and your diaphragm is pushed down. The air you breath in expands the lungs to capacity and then some of the air is blown back out. \n\nWhile the dictionary tells us that yawning is caused by being fatigued, drowsy or bored, scientists are discovering that there is more to yawning than what most people think. Not much is known about why we yawn or if it serves any useful function and very little research has been done on the subject. However, there are several theories about why we yawn. \n\nHere are the three most common theories: \n•The Physiological Theory -- Our bodies induce yawning to drawn in more oxygen or remove a build-up of carbon dioxide. This theory helps explain why we yawn in groups. Larger groups produce more carbon dioxide, which means our bodies would act to draw in more oxygen and get rid of the excess carbon dioxide. Howeve

You do an abdominal thrust which goes in and up at the same time.  The thrust needs to be quick and hard to try to force air out of the lungs hard enough to expel the foreign material.

when you exercise you kind of like ripping your muscles. when they get repaired on their own they become bigger and stronger. i didnt give you an answer from medical point of view, but you ask any doctor and they tell you this, but in a better description. thanks to you.
