can someone clearly tell the difference between shallow breathing and hyperventilation-?

You can breathe as fast and shallow as you want and that's just what it is called "fast and shallow". Hyperventilation does not describe a breathing pattern, it describes what is occurring with gas exchange in the lungs. "Ventilation" refers to carbon dioxide diffusion into and out of the lungs. If you are hyperventilating, this means that you are blowing off too much CO2. If on the other hand you are hypoventilating, then you are retaining too much CO2. Hyperventilation can be caused by many things including pain, fear, anxiety, and stimulating drugs.

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).

OK SERIOUS ANSWER HERE!!!\n\nThere are 2 systems in our bodies.  Voluntary and Involutary..\n\nVoluntary: is your nervous system... i.e. When you are breathing really slow your heart doesn't need as much oxygen so it slows down.. When you are breathing really fast there is more oxygen so your heart beats faster..\n\nInvoluntary: Anything that is coltroled by your actions rather than on its own.. i.e. walking, talking, reading, etc. \n\nWhen you have to think about something It makes the switch from Voluntary to Involutary..\n\nThis is the reasoning behind your being able to conrtol your heartbeat..

alkalosis.  Hyperventilation is breathing off the acid.

The system that controls the inflation and deflation of your lungs is both INVOLUNTARY and VOLUNTARY.\n\nAs an aside, your lungs have no muscles. It is your DIAPHRAM that does all of the work to make you breath.\n\nThat muscle is involuntary all of the time. You do not have to think about breathing to do so. In your sleep, while watchin tv, etc. However, you can choose to take a deep breath, or hyperventillate or even hold your breath briefly.\n\nYour body will not allow you to self hold your breath. After a certain point, you WILL breathe no matter what as the involuntary part kicks back in and overrides the choice to not breath.\n\nSo, no muscles inlngs, the lungs are inflated by the disphram muscles and they are both voluntary and involuntary.

It varies\nAdults: 12 to 20 breaths per minute\nSee the link for the rates for newborn, infant, preschool children, older children & adults\nvolume of oxygen per minute\nAnd much more on the respiration rate

For a very short time, yes. People tend to forget about what's called "dead air spaces". Yes, you're exhaling some co2, but a good deal of that exhalation is still o2 ( it's not all used in a breath) and even more so in dead air spaces. These are areas in your body from the top of your lungs to the tip of your lips, that don't do any gas transfer to or from the blood stream. It's still normal, oxygen rich air in there.\n I also disagree with what one person has stated here, that artificial respiration is only a method to get the lungs moving. \n It IS in fact a method of oxygenating the blood stream and keeping a victim viable in the absence of their breathing on their own.

Everything is fine.  It is just the changes in pressureas the plain goes up and down.  When the plain is taking off swallow or chew gumm to help them adjust to the lower amounts of pressure, and then when it is landing hold your nose closed and try to breath through it until you feel the pressure change.  don't do it too hard though and stop once the pressure changes in your ears.  Repeat this as necessary.  It can be pretty confusing and weird at first huh?  Nothing is wrong with you though.

How do you know you're breathing? You just do.

if she's having oxygen at 3 when her prescription is just 2 L/min then you should be concerned. carbon dioxide is the main reason why people breath since the brain signals the respiratory organs that theres CO2 in the body, upon breathing the CO2 is expelled. in you sister's case, the brain would think that she doesnt need to vbreath since she has enough oxy due to the apparatus until such time that the brain will forget to send a signal to the respi organs and she will also forget to breath, literally.

well theres one for pulse and one for oxygen saturation.  check also with respiratory tech infor

Take a deep breath in, but don't hold it, just keep the air in your lungs for about 3-5 cycles (the time it would take for you to breathe in and out 3-5 times). \n\nA hiccup results from your brain thinking your lungs aren't getting enough oxygen, so it forces oxygen in until something turns the trigger off. Holding your breath doesn't turn the trigger off, because the hiccupping is centered around the inhale, but holding your breath = pausing the exhale. But if you keep your lungs in a posture of continuous inhalation, the hiccups stop immediately because the brain realizes the lungs are fully saturated.

First of all, rebreathing into a paper bag is no longer the recommended treatment for hyperventilation, as CO2 levels can rise too quickly or can exacerbate a larger problem.\n\nThere are many causes for hyperventilation--lack of O2 is just one of them.\n\nRebreathing exhaled air increases the CO2 in your lungs which prompts you to breathe deeply rather than quick shallow breaths. You are using one of your body's many feedback control systems to return to normal breathing patterns.

A one word synonym for fast breathing that comes to mind is the word "hyperventilating." \n\nHope that's what you were looking for.

think about it..\n\nhyper = too much\nventilate = breathing\n\nthey're breathing too fast and taking in too much oxygen.. While we need oxygen, we also need carbon dioxide (which we breathe out).. its a balancing act..\n\nso breathing into a bag reintroduces the carbon dioxide and balances the gases in your blood.

No....your breathing rate doesn't jump that fast...and if you've been running for a while, you'll be exhaling as fast as you inhale....

Ventilation - the physical act of moving air in and out of the lungs.\n\na)  Passage way resistent would reduce the volume of air that could be inspired - either by hyperinflating the lungs thereby not allowing new air to fill the lungs with breathing OR by the simple resistence itself, no allowing air in (but its usually the former).\n\nb) Decrease lung compliance would reduce the inspiratory volume and therefore decrease ventilation.\n\nc)  If the lungs did not secrete surfactant, the surface tension of alveoli would be much higher and it would not be able to inflate normally.  Therefore ventilation would be reduced again.\n\nSo after I help you with your homework, are you going to buy me lunch?
