Key result
Hyperventilation disorder was associated with increased variability of resting tidal ventilation compared to healthy controls (median CV of VT 36% vs 26%, P=0.020).
Case-Control (n=37)
Absolute Event Rate: 36% vs 26%
p-value: p=0.020
Patients with hyperventilation disorder exhibit increased variability and complexity of resting ventilation without increased chemical drive.

May aid recognition of hyperventilation disorder; leaves open diagnostic utility and mechanisms in prospective cohorts.
Bokov et al. (2016) conducted a case-control in Hyperventilation disorder (n=37). Hyperventilation disorder vs. Healthy subjects was evaluated on Variability of resting tidal ventilation (coefficient of variation of tidal volume) (p=0.020). Hyperventilation disorder was associated with increased variability of resting tidal ventilation compared to healthy controls (median CV of VT 36% vs 26%, P=0.020).
