MODE OF EXECUTION OF DIVING WORKS WITH USING AIR FOR BREATHING Russian patent published in 2006 - IPC B63C11/00 

FIELD: the invention refers to diving works.

SUBSTANCE: the mode of execution of diving works with using air for breathing is fulfilled by way of submerging to a working depth, a diver's work during 30-60 minutes and decompression. At that the submergence of divers is carried out in accord with the stepped regime of decompression taking into consideration the nitrogen diffusion gradient of no more than 250 kPa to notice any expressed manifestation of nitric narcosis. The decompression is fulfilled in such a manner that during the whole period of its extension with the exception of its final stage the nitrogen strain in liquid mediums and cell structures would not prevail the value of the exterior pressure and in time of conducting the final stage of decompression it would make an average value of permissible nitrogen supersaturation for cell structures of the diver's organism equal 40 kPa.

EFFECT: such execution of the mode provides reducing of the risk of development of decompression disorders.
