Gas altering convective thermoregulation blanket

A convective thermoregulation blanket comprising:

• an interior surface;
• an exterior surface, wherein a portion of the exterior surface is configured to be in contact with a patient;
• an inlet opening extending between the exterior surface and the interior surface of the convective thermoregulation blanket, the opening configured to receive a supply of thermal regulated convective air;
• a filter coupled to and extending across the inlet opening between the exterior surface and the interior surface, the filter configured to filter harmful airborne contaminants in the supply of thermal regulated convective air.

A convective thermoregulation blanket comprising:

• an exterior surface, wherein a portion of the exterior surface is configured to be in contact with a patient;
• a plurality of interconnected distribution channels located internal to the convective thermoregulation blanket, the plurality of distribution channels including a primary distribution channel having an interior surface;
• and
• a first inlet opening extending between the exterior surface of the convective thermoregulation blanket and the interior surface of the primary distribution channel to deliver thermal regulated convective air into the primary distribution channel;
• wherein at least a portion of the primary distribution channel comprises a filter material, the filter material configured to filter unfiltered thermal regulated convective air in the primary distribution channel and to provide the remaining plurality of distribution channels with filtered thermal regulated convective air.
