how do asphyxia differ from periodic breathing? explain it.?
457871
Asphyxia is where one person's air supply is being choked off or in the process of BEING choked off. (Not a good thing!)\n\nPeriodic breathing is a condition originating from an earlier medical or physical problem in that person's life where they couldn't breathe normally like they wanted to. (Preemies are a good example. Underdeveloped lungs shortens their ability to breathe normally. So they had to adapt.)\n\nMost people take regular and deep breaths. Shallow breathing is common.

interesting question.\n\nthe actual point when someone "passes away" i suppose could be a little unclear based on this statement. Usually it would just be defined as when your heart no longer beats, but i suppose your brain would be able to function for a short while afterwards, depending on how you die.\nMy guess is that it would be for about as long you can hold your breath, since a lack of blood is basically equivalent to a lack of oxygen. \n\nAfter a certain point though, brain function would be impossible. This is why when people are resuscitated, it is usually almost immediately after they die, if they wait too long it could result in some serious brain damage.

You're asking about two different techniques for keeping a victim viable.\n In CPR, there is no mouth contact. The chest is compressed in regular intervals, forcing the heart's chambers to move blood throughout the body.\n Artificial respiration ( 2nd part of your question) is a method to put oxygenated air into the lungs, where it can be picked up by either a beating heart's blood flow or the flow produced by CPR.\n Artificial respiration alone, is used on a victim that has a detectable pulse, but not breathing on their own. This CAN result in a victim being revived on the spot.\n CPR is administered in conjunction with artificial respiration, to a victim that has no detectable pulse and is not breathing. The chances of immediate revival using these two methods at this point, is slim to none. It's just to keep the victim viable until a heart  defibrillator can be used to kick start the heart. So, for the first part of your question, nope, it ain't gonna happen by CPR alone. As to the second part of your question, that wouldn't happen with me. I carry what's called a pocket mask in my emergency med kit. It fits over the victims nose and mouth and I can use it to administer artificial respiration without any actual oral contact. It also has a hook up for the attachment of an oxygen bottle so doubles as an O2 mask. Never know who's infected with what these days.

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..

They are not the same.\n\nCardiac arrest is when a heart stops beating / contracting. That is when you give a CPR and either shock the heart or give appropriate drugs to treat it.\n\nHeart attack is when the heart muscles die as a result of not getting enough blood supply. Here you give drugs directed to improve the blood supply of the heart. In most cases the heart keeps beating after the heart attack. But rarely, if many of the muscle fibers are dead, the person's heart stops beating too. In those cases, cardiac arrest happens as a result of heart attack.\n\nHope its clear to you now.

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.

My wife suffered with GBS for 3 times in years 1998, July 2005 & June 2006.  The 3rd attach in this month was mild one and she recovered within 10 days only. As far I know (from doctors & Web sites) the death rate is less.  When it reaches the lungs level, the lungs may not work properly. That is only the dangerous one.  For the 1 & 2nd  time she suffered a lot to take breath (between 15th day to 21st day). She suffered to take breath only in night times.

Since none of us died, we don't know if that happens. It may be crazy survivor stories. Or it could be when your brain can't get enough oxygen, you may have synestatic experiences due to a hormone imbalance.

?? \n\nWhy would there be any disadvantages associated with adequate ventilation since breathing is occuring at a normal rate and the oxygen is being delivered to the cells?

Breathing is controlled by the autonomic nervous system as long as we don't focus on it. When a child holds his or her breath long enough for the autonomic nervous system to kick in, they begin to breathe whether they want to or not.\n\nIt's an attempt to manipulate you. Ignore it and the behavior will cease.

Breathing, the process whereby an organism (living thing) obtains oxygen from its surroundings, to take part in internal chemical reactions which break down food to release energy. Breathing also usually gives out waste carbon dioxide as an unwanted by-product of these reactions. Breathing is one aspect of respiration, which is a term that includes both physically obtaining oxygen, and also using it in chemical pathways inside cells to release energy—the process of cellular respiration\n\nMany aquatic animals obtain oxygen dissolved in the water by muscle-powered movements, such as when the forward motion of a fish or the pumping actions of its mouth and throat force a flow of water over its gills ( See also Fish). This is underwater breathing. Tiny organisms “breathe” by the process of passive seepage or diffusion of oxygen through their body surfaces. Plants also obtain oxygen by diffusion from the air or water around them, usually into the leaves.

I'm also amazed at the answers including the preceding one. It's true it's all about bouyancy. But is bouyancy affected significantly by the dissolved oxygen in the tissues? According to the ref., bouyancy is just about lung capacity, bone, fat and muscle ratios. And of course the salinity of the water. Also, panic-induced body tension can reduce lung capacity and muscle performance.  \nAnyway, a change in tissue oxygen level would happen slowly; it's a diffusive process. Second, the density difference of water with and without dissolved oxygen has to be minute since oxygen is only sparingly soluble.

yes, its called sleep apnea, you dont get enough oxygen and you pass out, it can actually be fatal

Every time you exhale, you breathe out most of the air you breathed in. While the air is in your lungs, oxygen travels from air to blood and CO2 from blood to air, in each case moving naturally to where it is less concentrated.\n\nHow long it takes the average oxygen molecule from being absorbed to being breathed out again as part of a carbon dioxide molecule is a really good question - I have no idea if anyone has even calculated it, but we can try.\n\nMost people pass out if their blood oxygen level drops below about 80% - and most people can hold their breath for maybe 4-5 minutes (the record is almost 9 minutes by Houdini, but that's someone trained and a bit freakish). That implies you use 20% of the oxygen in, say, 5 minutes - so it would take 25 minutes to use it all, if that were physically possible.\n\nBTW, I'm prettty sure it's 8-9 pints of blood. The normal O2 reading in arterial blood is around 10-13 kPa, but I'd have to admit I don't know how to convert that to a mass (or free volume) of oxygen.\n----\nOoh, here you go: arterial blood contains about 20ml of oxygen per 100cc. Your blood volume is about 5 litres, so that would mean your body contains rather less than a litre of oxygen (because not all of your blood is fully oxygenated).

I think you mean gills.\n\nThere are artificial liquids available:\nLiquid breathing is a form of respiration in which a normally air-breathing organism breathes an oxygen rich liquid (usually from the perfluorocarbon family), rather than breathing air. It is used for medical treatment and could someday find use in deep diving and space travel. Liquid breathing is sometimes called "fluid breathing", but this is misleading as both liquids and gases are fluids.\n\nNanotechnology is be used to create respirocytes which act as artificial red blood cells and could allow you to hold your breath for 1-2 hours underwater.

asphyxia: loss of air in the body/not receiving enough oxygen\n\nphilia: like a fetish or something\n\nohdear. that's sick.

They hold their breath. They can hold their breath for a very long time because they have a very efficient metabolic rate that allows them to control the amount of oxygen required by their bodies. Their heart rate drops and blood supply to external parts that do not require so much oxygen are reduced.
