This method can also be performed by only two first responders: the chief plays the role of the first team member, and the only team member deals with the board (neither the head nor the ankles are gripped). This is rather traumatic for the casualty, but can be used when there is non suspicion of trauma, either in emergency (e.g. to transport a cardiac arrest when advanced life support cannot be performed on site), or when the first responders are lacking.
