Changes in Fingure-Pulse Volume (FPV) during CO2 inhalation were studied in patients diagnosed as having Anxiety disorder with history of panic attacks. Waxing and Waning of the FPV was observed in all the cases after CO2 inhalation, and this pattern was significantly intensified during panic attacks during the study. The significance and the mechanism underlying the same is discussed.
