ABSTRACT: A computer aided health care system for use by a paramedic. Findings taken from the patient by the paramedic are assigned numerical codes by use of preprinted forms. The paramedic uses a keyboard to enter the numerical codes into a fixed purpose computer. The computer compares the findings with a number of disease definitions stored in its memory. The computer then operates a printer to list numerical codes for all treatments to be administered. The paramedic finds these codes in a treatment and diagnostic manual that gives the name of the disease and specific instructions for its treatment, in the language of the paramedic.
