[Sleep apnea syndromes. Treatment with continuous positive pressure by the nasal route].
Nine patients with severe, predominantly obstructive sleep apnoea syndromes were treated during one night by continuous positive pressure under polygraphic monitoring. Three patients did not tolerate the treatment for either mechanical reasons (2 cases) or ventilatory reasons (1 case). In the remaining 6 patients, continuous positive pressure resulted in reorganization of sleep and disappearance of obstructive and central apnoeic episodes. This effect was incomplete at low pressure (2 cm H2O) and complete at pressures of 6 to 10 cm H2O. The fact that continuous positive pressure was effective against both obstructive and central apnoea suggests that its mode of action is not purely mechanical but involves the central ventilatory control, probably by a reflex mechanism. In view of its effectiveness, continuous positive pressure appears to be the treatment of choice for sleep apnoea syndromes.
