[edit] Summary

The effects of Sodium Nitroprusside(Nipride), a peripheral vasodilator, on the finger photoplethysmograph (PPG) and blood pressure (BP) of a sedated subject. As expected the PPG amplitude increases after infusion and additionally the Respiratory Induced Variation (RIV) becomes enhanced.

The subject is under general anesthesia and mechanically ventilated. The mechanical ventilation can make the RIV easier to detect. Two single breaths are highlighted.

The original figure was provided by Kirk Shelley, Yale Medical School and modified by Stephen Linder, Dartmouth College.
