ABSTRACT
Currently, more than 2200 patients in the Netherlands receive chronic ventilatory support. In the majority of patients this leads to increased survival without any complications. Nevertheless, in case of ventilatory support via a mask, problems such as skin irritation, leakage and claustrophobia can occur. In case of tracheostomy, it can lead to increased pulmonary secretion. Diaphragm pacing with an external pacemaker might be an attractive alternative to prevent these symptoms as it can replace ventilatory support by mask or tracheostomy. Current indications are patients with spinal cord injury or with congenital central hypoventilation syndrome who are chronically respiratory insufficient. In our experience, patients can be completely or partially weaned from mechanical ventilation when using the diaphragm pacer. In the Netherlands, the technique is only performed at the University Medical Center Groningen.

Respiratory insufficiency developed in a man aged 68 after cardiac surgery and in a man aged 60 with COPD and a history of cigarette smoking after an attack of 'flu', while in a woman aged 70 with non insulin-dependent diabetes mellitus it had been present for years. All three had bilateral diaphragmatic paralysis. The diagnosis is based on the triad orthopnoea, paradoxical abdominal movements during respiration in the recumbent position and a decrease of the vital capacity in the horizontal as compared with the sitting position. The patients' physical condition could be improved with the aid of (noninvasive) ventilatory support.
