Abstract
Patient monitoring methods comprising the steps of measuring a plurality of medical parameters, transforming each medical parameter to a function indicative of at least normal and critical levels of the parameter, comparing each function to a prescribed sequence of reference values and on the basis of the comparison generating for each parameter a corresponding danger level, selecting one of the danger levels as a vital function status (VFS) indicator, and displaying the VFS indicator. Each parameter is transformed to a sigmoid function in accordance with pre-selected maximum and minimum values and a pre-selected baseline value adapted to the patient being monitored. A maximum value of the danger levels is selected as the VFS indicator. The VFS indicator will be such that any physician can have, without any previous knowledge of the patient, a reasonably good idea as to the condition of the patient.
