Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The objective of the present study is to assess the tolerance and the efficacy of transnasal insufflation to treat sleep apnoea in acute stroke patients. Trans-nasal insufflation is a less invasive method to treat apneas/hypopneas than CPAP. It delivers warm and humidified air at a continuous high flow rate (18 l/min) through an open nasal cannula. It is applied during the one night.

Summary
Brief summary
Sleep disordered breathing (SDB) is frequent in acute stroke patients and is associated with early neurologic worsening and poor outcome. Although continuous positive airway pressure (CPAP) effectively treats SDB, compliance is low. The objective of the present study was to assess the tolerance and the efficacy of transnasal insufflation (TNI), a less intrusive method, to treat SDB in acute stroke patients.
