title: Calculation of the percentage of a narcotic gas to permit abolition of the high pressure nervous syndrome.
abstract: A theoretical method is derived for computation of the interactin of pressure and a weak anesthetic such as nitrogen or other narcotic gases in a two-dimensional material so as to prevent signs and symptoms of the high pressure nervous syndrome. A ratio of one part nitogen to 9 parts helium (pressure) is derived, which is in excellent agreement with previous human experiments in men at 31 ATA, with PO2 = 0.5 ATA.
