SYNOPSIS The effect of voluntary hyperventilation was assessed in 22 cluster headache patients (8 in a cluster period and14 in a remission) and 19 healthy individuals. Using an ear oximeter and a capnograph with a nasal probe, the oxygen saturation (SaO 2 ) and the end‐tidal CO 2 were monitored continuously. During the hyperventilation per se, cluster headache patients and controls showed absolute values of end‐tidal CO 2 and of SaO 2 Of the Same order of magnitude. In the posthyperventilation phase, however, the average of the lowest SaO 2 levels was lower in controls than in cluster headache patients. In the posthyperventilation phase, headache patients outside the cluster period showed a trend more similar to that of the controls with respect to SaO 2 than did those inside the cluster period. The observed discrepancy might, if reproducible, be a consequence of an altered chemoreceptor sensitivity in cluster headache patients during the bout.
