Psychophysiological assessment of respiratory function in panic disorder: evidence for a hyperventilation subtype

Psychosomatic Medicine
M T Hegel, R J Ferguson

Abstract

Previous research has found differences in respiratory function between panic disorder and other anxiety disorder populations. These differences have been explained as reflecting either a) a specific feature of panic disorder, b) merely a sign of increased general arousal, or c) a result of population sampling error. The current study addressed the question of such differences by using improved methodology over previous research. A preliminary evaluation of respiratory symptoms during panic attacks was undertaken as a means of identifying a respiratory-sensitive subtype of the panic patient. Seventeen panic disorder patients (PD), 18 patients with generalized anxiety disorder (GAD), and 20 normal control (NC) subjects were administered a psychophysiological evaluation composed of baseline, stressor, and recovery phases. Panic patients were measured for the severity of respiratory symptoms during panic attacks. End-tidal CO2 (EtCO2) and respiration rate were measured throughout the psychophysiological evaluation. PDs demonstrated significantly lower baseline EtCO2 levels than the GADs and NCs, in spite of being equivalent to GADs on baseline anxiety levels. Moreover, panic patients reporting a high level of respiratory symptoms ...Continue Reading
