Abstract
A method for platelet preservation comprising placing a composition comprising platelets in a gas mixture comprising xenon and oxygen under pressure of about 0-10 Bars at a first temperature of about 18° C.-37° C. for a first period of time, and then subsequently cooling the composition to a second temperature of about 0,1° C.-6° C., and holding the composition under the pressure and in the second temperature for a second period of time.

A method for platelet preservation that can be used to extend the life of useable platelets beyond five days comprising the steps of:
- a) placing a composition comprising platelets in a gas mixture comprising xenon and oxygen;
- b) maintaining said composition comprising platelets in the presence of said gas mixture for a first period of time and at a first temperature until said xenon in said gas mixture has at least partially saturated said composition comprising platelets;
- c) cooling said composition comprising platelets that is at least partially saturated with xenon to a second temperature, said second temperature being less than said first temperature;
- and,
- d) holding said composition comprising platelets at said second temperature for a second period of time.
The method as defined in claim 2, wherein said composition is placed into a bag or container permeable to said gas mixture and said composition is exposed to said gas mixture in a hermetically sealed chamber.
