| 摘要 |
A post-operative, arterial patency monitoring system for monitoring patency of an artery of a limb is described, the system comprising one or more probes (2A-2C). The system further comprises means for processing the probe output signals to produce a first arterial blood supply metric and a second, different, arterial blood supply metric; means for using a predetermined function that takes as its arguments at least the first and second arterial blood supply metrics to produce a combined arterial patency metric. The first and second arterial blood supply metrics may be different ones of skin color redness, skin temperature, arterial blood supply strength or peripheral pulse rate. A probe positioning apparatus (40) comprising a visual indicator is also described. |
