Abstract
A non-invasive method and system for assessing the survival of a transplanted flap involve the following steps. A control unit instructs a variable-frequency current generator circuit to generate a constant current at a fixed frequency and pass the constant current through a detection electrode. The detection electrode detects a bioelectrical impedance of the skin to which the flap has been transplanted, and the bioelectrical impedance of the skin is compared with a pre-defined threshold value. If the bioelectrical impedance of the skin exceeds the pre-defined threshold value, it is determined that an abnormal condition has occurred.

A non-invasive method for assessing survival of a transplanted flap, comprising the steps of:
- A. generating a constant current at a fixed frequency, and passing the constant current through a detection electrode;
- B. detecting with the detection electrode a bioelectrical impedance of a skin with a transplanted flap;
- and
- C. comparing the bioelectrical impedance of the skin with the transplanted flap with a pre-defined threshold value, and if the bioelectrical impedance of the skin with the transplanted flap exceeds the pre-defined threshold value, determining that an abnormal condition has occurred.
