To solve a problem that a time for storing an extracted organ is limited to four hours by a storage method most frequently used for human heart transplantation, while natural water based on physiological salt solution for extracted organs has been used as a pre-treating liquid before the storage, and a problem that the extension of the organ storage period is needed, because the acute shortage of donors for increasing recipients becomes a large problem.

This method for extending the organ storage period and for improving the efficiency of revival is characterized by using carbon dioxide as a gas for stopping the life activity of the organ.
