What is ecmo and how does it work?
147820
ECMO (Extracorporeal Membrane Oxygenation). It's a life support system that circulates the blood through an oxygenating system. It's similar to the heart-lung machine used during open heart surgery. ECMO has been used for treating patients with severe smoke inhalation, people with irreversible heart failure, and people in acute respiratory distress. It's a fairly advanced topic.

I don't mean to be contrary, but I think the previous answer missed the question, or device being described.  There are portable oxygen tanks, where the oxygen is generated back at a chemical plant, and just released.  Those need tank refills.  I think you want to know about the actual home based oxygen generators (not too different in size from a home electrical generator), that plugs into the wall, and never needs to be refilled, like the one my grandmother uses.  \n\nThese are often called "concentrators" instead of "generators", because they concentrate the oxygen already in the air.\n\nThese generators use air as the source, and enrich the amount of oxygen in the air, releasing the nitrogen and other components back to the environment.  The main method for doing this is by compressing the air, and leveraging the different physical properties for components within air (oxygen, nitrogen, etc).\n\nThe main components include a compressor (hence why they are inherently noisy), to push the air across membranes or sieves.  The speed of absorption through the sieve is different for different gases in the air.  The concentrator uses this to increase the concentration of oxygen, before it is delivered to the user.\n\nThey are pretty neat devices.

HOW IT WORKS \n\nThe Egg Diet is a low carbohydrate diet that works by nutritional fasting. Nutritional fasting is where you cease eating certain, but not all, nutrients. In this diet, the only nutrients that we cannot consume are carbohydrates. Carbohydrates are the fuel for fat cells. By eating unlimited quantities of eggs, steak, cheese, and other foods that are low or void of carbohydrates, we can starve ourselves of fat fuel. \n\nNormally, when you eat carbohydrates, they are reduced to a simple sugar called glucose. In addition to your fat cells, all the other cells in your body also burn glucose. Excess glucose that is not used by the other cells is converted to fat and stored in the fat cells. When you don't eat enough carbohydrates to keep all your normal non-fat cells happy, your body has no choice but to start pulling from its fat reserves and converting the fat back into glucose. The important thing to remember is that this happens even if you have been stuffing yourself full of steak, cheese and eggs. Knowing this, we can lose fat while eating all we want of low carbohydrate foods. \n\nNormally, a person's diet is extremely high in carbohydrates (sugars and starches) and other nutrients. We more or less consume a balanced diet every day consisting of the four basic food groups - meat, milk, bread, and fruits and vegetables. While a balanced meal is a very nutritious meal, it is not acceptable for dieting. It is a long standing joke that pizza is a balanced meal. It contains all four food groups - the crust (bread), pepperoni (meat), cheese (milk), and tomato sauce (vegetable). However, if you were to just eat pizza all the time, your waist would swell up like a water balloon in no time at all. The part of the pizza that makes you fat is the crust. There is no other ingredient that does this. \n\nWITHDRAWAL SYNDROME \n\nBecause we are so used to eating carbohydrates by the shovel full, most of us are addicted to them. As such, you can expect to go through carbohydrate withdrawal when you first start this diet. Actually, the term addiction and withdrawal probably isn't the correct term to describe it, but you can pretty much plan on getting weak or sick when you first start the diet. This sickness usually manifests itself as simple weakness. Some people get a little nausea and others may get headaches. It usually only lasts for a day or two. If it becomes unbarable, you can always pop in a lifesaver candy to spread it out over several more days. What is actually happening during this period is that your fat cells are shifting gears from "Forward" to "Reverse". \n\nKnowing this, you shouldn't get too worried if you get a little sick when you first start this diet. However, as with all diets, you should consiult with your doctor before starting it to see if it is OK for you. While you are there, have the doctor test your cholesterol level. Then, after you have been on the diet for a while, go back and have it tested again and compare the results. For many people, their cholesterol will be lower after they have been on the diet a while. This flies in the face of all the anti-egg people who say that eggs are bad for your cholesterol level. I say that the proof is in the pudding. \n\n\n\n--------------------------------------------------------------------------------\n\nSugars are in the carbohydrate family - and so are starchy foods like bread, flour, pasta and potatoes. While sugars are the fastest substances that your digestive system can process into Glucose, starches are the next fastest. So fast in fact, that to your digestive system, there isn’t much difference. It takes only a few minutes to process certain starches, like bread for example, into Glucose. \n\nFats, on the other hand, are very complex molecules. Your digestive system has to really work hard to process fat into Glucose. Consequently, a lot of unprocessed fat simply passes on through and never gets converted. Ano

I believe it developed on time as a practical ecomonic choice or industry standard.\n\nYou would want to use a very low pressure if possible but still it needs to be high enough to actuate instuments and control devices.

Every one seems to have it right, it's just a basic pump , it pumps blood around the system, like a central heating system ,  nothing really very clever about it, all you have to do now is explain what a Central heating system is all about. Good luck !!.

I assume this is based on the principle of Osmosis. I would like a bit more data before answering further.

his applies only to transfer pumps since we deliberate add a gas load to the chamber and measure the quantity of gas issuing from the mechanical pump's exhaust. The method works as long as the gas chosen is not condensable, not captured in the foreline trap, does not dissolve in oil and is present in sufficient quantity to be measured.\n\nIf the mechanical pump has gas ballast, make sure it is off. Note the chamber's steady state pressure under the gas load. Put a bubble flow meter on the pump's exhaust, and measure the flow rate in cc per sec at atmospheric pressure. Using the gas in = gas out (at constant chamber pressure) principle, the gas entering must equal the measured throughput. If more precise numbers are needed, measure the exhaust gas temperature and the barometric pressure and re-calculate the quantity of gas at STP with Boyle's and Charles' law combined:\n\n(P1 x V1) / T1 = (P2 x V2) / T2\n\nExample The measured flow of gas at the pump's exhaust is 2.3 atm cc per minute from a chamber at a measured pressure of 1.4 x 10-5 torr. The exhaust gas temperature is 32°C and the barometric pressure is 750 mm Hg. What is the (corrected) effective pumping speed from the chamber?\n\n2.3 atm cc per min = (2.3/60) atm cc per sec\n= (2.3/60) x (760/1000) torr.liter per sec\n= (2.3/60)x (760/1000) torr.liter per sec at 750 torr and 32 °C\n= (2.3/60) x (760/1000) x (750/760) x (273/305) torr.liter per sec at STP\n= 0.0257 torr.liter per sec\nEffective pumping speed\n= (0.0257/1.4x10-5) liter per sec\n= 1838 liter per sec

The basic theory is that if you pump steam into a place where there is a piston, the piston will move up.  Then you release the steam and the piston will go down.  You connect the piston to something to get movement, such as some gears that turn the propellers or connect them to the wheels.  It's a bit more complicated than that, but that's basically how it's done.
