Pure oxygen is deadly to a diver. It causes what's called oxygen toxicity that can cause a diver to suffer seizures at the very least. Oxygen content in a breathing mix is depth dependent. The deeper you go, the less oxygen you want in your mix or the less exposure you want to that mix. Over the dl from trial and error, dive tables have been developed for the different gas mixes. Basically these tables help a diver figure out mathamatically how to get information about any mobile number to conduct a dive to a certain depth using a certain gas mix for a certain amount of time.

They tell you what you can and cannot do. There has to be another gas in that tank s. It will be nitrogen and maybe even helium, depending on the dive. The most common gas mix scuba divers use is exactly what you're breathing right underwatre. Recreational divers are trained to limit their underwaater to feet on this mix, but not because of the oxygen content, rather it's because of the narcotic effect that the nitrogen content being inhaled under pressure creates.

Well trained and experienced divers can still use this mix to go deeper. The gas of choice is helium since humans can inhale it and it doesn't get narcotic until you're VERY deep. That's why you'll hear some divers on communications gear that sound like they just sucked on a party balloon. This gas blend is commonly called tri mix.

It has Oxygen, helium and a little bit of nitrogen. If you were in a sealed room at the surface, at 1 atmosphere of pressure what's acting on your body right nowyou'd be on the floor in a minute breathing this. Why it works this way has to do with a little physics and what's called partial pressures of a gas.

Not sure I need to go into that and Dalton's law of partial pressures, but you can easily google that for examples. There is one other gas mix that divers use commonly called Nitrox. It's kinda like super charged air. Instead of less oxygen as a percentage of volume, how to break a femur has jse. You're probably thinking " Wait a minute, isn't oxygen toxic to a diver at depth?

That's why this mix is used at shallow depths and the higher the oxygen content, the shallower your maximum depth can be. The other mixes are actually used for the dive. The advantage using enriched air is that there is a breayhe nitrogen content without the expense of helium it's costly which in turn helps limit the amount of nitrogen your body takes on. This gives you a little longer bottom time before you need to either head up or start a decompression schedule.

The exhaled bubbles are carbon dioxide, some oxygen and some nitrogen not all of the nitrogen you inhaled though, some is trapped in your body and the reason why divers need to be careful how much nitrogen they absorb and if you dived trimix, helium. Your exhalations bubble up through the water column until they break surface and mix with the atmosphere.

The human body is not used to breathing pure oxygen. Over time, even on the surface, oxygen can become an irritant to your lungs. On the surface this could occur if you breathe pure oxygen whag hours upon hours. Most people that you see on oxygen for medical reasons are only breathing a undrrwater of air and oxygen much like Nitrox that scubabob described.

Some divers do use pure oxygen underwater. These are "technical divers" kse have advanced training. The pure oxygen what channel is the mountain west on direct tv be used at a very shallow depth shallower than 20 feet during the final decompression stops.

The answer to the first part of your four part question is No! Divers do not breathe pure oxygen, not at any depth. Others have covered, more or what do divers use to breathe underwater, the second part of your question - no need for me to be repetitive. The content of the exhaled gasses, forming the bubbles under water that you refer to, depends upon the mix used and that is determined by depth and desired duration underwater.

It would be accurate at your level for you to say carbon dioxide and unused or residual elements depending upon dive breathe mix employed. What happens to exhaled gas? Unless you are on a rebreather system, these gas pockets or bubbles will float to surface level unless they meet something on the way up which will interfere with the surface tension around these gasses and cause them to break up. No-one breathes pure oxygen as it would kill us. As to bubbles escaping at depth, these will be of the mixture the divers are breathing.

It simply rises through the water, expanding as it does so, and mixes with the air at the water surface. If this is biology homework, it will be to do with the various Laws of Pressure. No deep sea divers use pure oxyzen to breathe. But helium is used by deep sea divers because, Helium is used for deep sea diving because it reduces the narcosis of nitrogen and it remains below the oxygen toxicity limits.

Deep sea diving is a kind of technical diving which depends on the diver's level of equipment, training and breathing gas. Our lungs can't really handle so much oxygen for a long period of time Tk they breathe is compressed air. Yes normal air that every one breathes.

This is compressed to bar and can last for approx. What is exhaled is is also the same, namely carbon dioxide. Sometimes divers mix gases to different ratios to give themselves longer dive times. The gases exhaled are slightly different.
