MANCHESTER - Manchester Police SWAT members trained in emergency and tactical medicine this week, including the use of a product the military uses to stop severe life-threatening bleeding in battle.

Lt. Maureen Tessier said the SWAT members do monthly training and last month's training focused on emergency medicine, perfecting skills like the tourniquet placed on the left leg of wounded police officer Daniel Doherty that is credited with helping save his life after he was shot by Myles Webster last March.

Tessier said a part of this week's training session included the use of mannequins that "bleed" and continue to do so if the tourniquet or special wound material is not property applied.

The special wound material used in the SWAT training, called QuikClot, is a rayon/polyester gauze that has been impregnated with kaolin, or white clay, an inert mineral that promotes clotting. The military uses the kaolin-based material in treatment of life-threatening bleeding from external wounds that are not suitable for tourniquet application.

Tessier said the SWAT members train monthly on various skills to maintain certification. The Manchester SWAT unit is one of 12 teams in the New Hampshire Tactical Officers Association and holds membership in the National Tactical Officers Association.

The emergency medical services consultant for the Manchester SWAT unit is Elliot Hospital's Dr. Tom D'Aprix.
