Caserias Posted March 5, 2017 Posted March 5, 2017 I wonder if your room becomes isolated from any gas coming in or getting out, -you will of course consume all the Oxygen in the room to the last bit- my question is that how can we delay it, does opening closets, opening your water bottle or killing some of your own cells makes a difference? Should i boil drinking water to save myself?
Sensei Posted March 5, 2017 Posted March 5, 2017 (edited) Should i boil drinking water to save myself? There is just up to 14-16 mg/L of Oxygen dissolved in water in 0 C according to this article http://www.fondriest.com/environmental-measurements/parameters/water-quality/dissolved-oxygen/ That's ~20 times less than in 1 L of air.. How about plants? They consume CO2 and release O2.. You would have to check how much CO2 single plant consume, and how much release O2, then check how much single person would consume O2 divide one by other, and you know minimum quantity of plants do you need. How about electrolysis of water with f.e. Gold electrode? It would release Oxygen in amount controlled by current. But you would have to figure out what to do with Hydrogen also produced in the process. ps. Someone who is in a panic, consume much more Oxygen than during normal breathing..

Will it give me at least someting?

You might use over half, well into which time you will have been struggling, but you won't get a whole lot further before your demise. http://www.geography.hunter.cuny.edu/tbw/wc.notes/1.atmosphere/oxygen_and_human_requirements.htm Edited March 5, 2017 by J.C.MacSwell
mistermack Posted March 6, 2017 Posted March 6, 2017 (edited) The bad news is that you will probably die of the effects of carbon dioxide, before the lack of oxygen kills you. Concentrations of one percent can make people feel ill, and some people will start to die once you pass five percent in the air. I suppose the people to ask are builders of submarines. They must have a some rules about air quality, and examples of people dying in closed rooms. Edit : Of course, NASA will have full data on what happens when the air runs out. Whether they have posted it on a website is another matter. Edited March 6, 2017 by mistermack
John Cuthber Posted March 7, 2017 Posted March 7, 2017 What you need is a lot of sodium peroxide, or a sink.
Sriman Dutta Posted March 25, 2017 Posted March 25, 2017 If you consider the idea about plants, you need to think that it's a CLOSED room. There won't be enough sunlight to support photosynthesis. So forget it. But electrolysis of water is a sound idea. It can give you a good deal of oxygen provided that you have enough of water and the electric bill won't trouble you. But the fact that there will be a concentration of carbon dioxide in the room due to respiration can cause suffocation. An excess of carbon dioxide will kill you. The situation will be critical in the presence of a lighted firewood or something like that, because it will produce carbon monoxide due to poor ventilation, and carbon monoxide will reach the blood stream to form carboxyhaemoglobin and that is poisonous enough to take your life. By the way, you might like to carry oxygen cylinders.
John Cuthber Posted March 25, 2017 Posted March 25, 2017 If you consider the idea about plants, you need to think that it's a CLOSED room. There won't be enough sunlight to support photosynthesis. My room has windows.
Sriman Dutta Posted March 25, 2017 Posted March 25, 2017 If there are windows, there is plenty of oxygen and there will be no need to struggle for survival.
John Cuthber Posted March 25, 2017 Posted March 25, 2017 If there are windows, there is plenty of oxygen and there will be no need to struggle for survival. Are you labouring under the delusion that oxygen permeates through glass or that all windows can be opened ? Obviously, you could try breaking a window- but that's not in the spirit of the question.
Sriman Dutta Posted March 25, 2017 Posted March 25, 2017 I get your point . You mean that the windows are made of transparent glass, through which sunlight will enter.
John Cuthber Posted March 25, 2017 Posted March 25, 2017 Maybe it's a cultural thing. Where you live are windows generally glazed?
