In general, the invention is directed to techniques for determining
appropriate first aid and applying first aid that is appropriate. A first
aid system receives patient status information from an input device or a
sensor, and presents first aid information as a function of the received
patient status information. The first aid system may be incorporated with
an external defibrillator. The first aid system may acquire patient
status information through an interaction with an operator, in which the
first aid system asks the operator to supply patient status information.
In one embodiment of the invention, the operator may supply patient
status information by touching a diagram representing at least a portion
of a human body.
