Air hunger.: The symptoms suggest possible hyperventilation as a cause of a blood ph shift and the sensation of air hunger. An easy way to test this hypothesis would be to hold a paper bag over ones nose and mouth to enable rebreathing of ones exhaled air which contains a high concentration of carbon dioxide. If hyperventilation caused the symptoms, they should resolve quickly as the blood ph is corrected.
