Summary
editEffects of an incision on a subject under general anesthesia on the photoplethysmograph (PPG) and blood pressure (BP). This incision generated a sympathetic nervous system response which suppresses blood flow to the skin, which manifest itself in a reduced PPG amplitude. This provides a mechanism for gauging the depth of anesthesia.
The original figure was provided by Kirk Shelley, Yale Medical School and modified by Stephen Linder, Dartmouth College.
