A self-propelled emergency stretcher includes an elongate frame having a set of wheels a track drive unit mounted thereto. The set of wheels includes first wheels at a front end of the frame and second wheels at a rear end of the frame, and the track drive unit is mounted between the first wheels and the second wheels. A plurality of actuators is configured to raise and lower the first wheels and the second wheels relative to the frame, so as to selectively switch the emergency stretcher between a self-propelled configuration and a manually-propelled configuration. In the self-propelled configuration the first wheels and the second wheels are out of contact with a ground surface below the emergency stretcher and the track drive unit is in contact with the ground surface. In the manually-propelled configuration the first wheels and the second wheels are in contact with the ground surface and the track drive unit is out of contact with the ground surface.
