Abstract: A rescue unit adapted to be towed by a snow mobile or the like includes a frame and attached skis. A patient support section is carried by the frame and includes a movable cover. An attendant support section is also carried on the frame longitudinally spaced from the head of a patient carried on the patient support section. The cover preferably includes first and second portions, the first portion being hingedly connected with one side of the frame and limited in its opening movement. The second cover portion is telescopically movable with respect to the first cover portion, and preferably has a transparent section for viewing the head of a patient being carried on the unit.
