Methods for reducing the probability of formation of thrombosis of deep vein, to elevate the concentration of atmospheric oxygen, and concentration of nitrogen.For monitoring of oxygen partial pressure, to control the degree of displacement of oxygen / nitrogen air arrival in response to oxygen partial pressure.To remix the atmosphere in the areas occupied and non occupied of the aircraft.For lowering the oxygen partial pressure to below the natural level and to adjust the concentration of nitrogen and oxygen within regions of an aircraft.The present invention relates to a method and arrangement to adjust the concentration of nitrogen and oxygen within regions of an aircraft.The method includes separating nitrogen from ambient air on board an aircraft.Through establishing a supply of nitrogen with high concentration and then discharge of nitrogen with high concentration from the supply to a region susceptible to fire.Uninhabitable, the aircraft, where the nitrogen with high concentration is stored, by means of reducing the capacity to the atmosphere in the same support combustion.Oxygen is also separated from the ambient air, through establishing a supply of oxygen with high concentration which is discharged in a cabin of the occupants of the aircraft.In this way, raising the level of concentration of oxygen inside the cabin to a level higher than the oxygen concentration that occurs naturally in the internal pressure of the booth tryThe.When it is determined that low oxygen concentration is required in the cabin of the occupants, the nitrogen with high concentration in storage is moved into the passenger cabin.By diluting the environment with high oxygen content.
