Two strategies to treat central sleep apnoea in heart failure. Adaptive servo-ventilation (left) targets both hyperpnoea and apnoea (two arrows). Positive airway pressure (+) maintains airway patency, attenuates reflex pulmonary afferent nerve initiation of hyperpnoea by lung congestion, and, by reducing both left ventricular afterload and end-diastolic wall stress, augments stroke volume to shorten the hyperpnoea cycle length and diminish hypocapnoea-induced apnoea. If apnoea is detected, back-up inspiratory support is provided. Transvenous phrenic nerve stimulation (right), as applied by Ponikowski et al.,15 stabilizes breathing specifically by preventing apnoea (single arrow). Intrathoracic pressure remains subatmospheric (–).
