A stretcher including a flexible base panel sized to support a person lying thereon during a rescue or extrication operation. The base panel includes a header end and an opposite footer end, and further includes a head-supporting region and a body-supporting region. The head-supporting region is sized to support the head and shoulders of the person and the body-supporting region is sized to support a human torso. The stretcher further includes a securement strap extending from the head-supporting region along one side of the base panel and crossing over to the body-supporting region at the other side of the base panel. The securement strap extends diagonally across the shoulder and torso of the person to arrest the shoulder and limit sliding movement of the person toward the header end of the panel.
