Table 1.
Percent of participants with PetCO2 below 30 mmHg during baseline and paced breathing for the three days of laboratory measurements.
Fig 1.
Changes in drop in PetCO2 between the three laboratory measurements with 95% confidence intervals.
Changes computed by subtraction of PetCO2 during paced breathing from PetCO2 during baseline. Note. * p < .05 *** p < .001; the significance of the difference between the laboratory measurements is indicated.
Fig 2.
Changes in the intensity of symptoms of hyperventilation between the three laboratory measurements with 95% confidence intervals.
Changes computed by subtraction of symptom intensity before paced breathing from symptoms experienced during paced breathing.
Fig 3.
Changes in the perceived pleasantness of the paced breathing task between the three laboratory measurements with 95% confidence intervals.
Note. ** p < .01; the significance of the difference between the laboratory measurements is indicated.
Fig 4.
Changes in decrease in unpleasant arousal between the three laboratory measurements with 95% confidence intervals.
Changes computed by subtraction of unpleasant arousal after paced breathing from unpleasant arousal during baseline. Note. *** p < .001; the significance of the difference between the laboratory measurements is indicated.
