[Successful treatment of diaphragm pacing-induced obstructive sleep apnea syndrome with nasal CPAP].

Abstract

We report a 71-year-old female patient with primary alveolar hypoventilation syndrome who received diaphragm pacing (DP) and developed obstructive sleep apnea syndrome (OSAS). Application of nCPAP markedly improved her nocturnal hypoxemia. The monitored polygrams before and after the application strongly suggested that the main mechanism of OSAS was an imbalance of activity between upper airway dilator muscles and pump muscles. Moreover, paradoxical movement of the rib cage is not necessarily due to upper airway obstruction. Monitoring of tidal volume and arterial oxygen saturation is essential for the diagnosis of DP-induced OSAS.
