Impact of Early Mobilization on SAH Patients Physiological Parameters

Not yet recruiting

Interventions: Device: lung ultrasound
Device: Transcranial Doppler
Device: near-infrared spectroscopy (NIRS)
Device: clinical examination

Brief Summary: The aim of the study is to evaluate the physiological response to out-of-bed mobilization in patients admitted to the intensive care unit for subarachnoid hemorrhage. More specifically, the aim is to measure the impact on cerebral perfusion, lung aeration, cardiovascular and respiratory parameters.

Detailed Description: In patients with subarachnoid hemorrhage, the mobilization strategy has been little studied. Several studies have already evaluated the consequences of mobilization in bed. Because of the deleterious consequences of prolonged bed rest, and in line with recommendations, practices have evolved towards early out-of-bed mobilization, which has shown benefits. However, the physiological consequences of out-of-bed mobilization have not yet been assessed. The aim of this study is to measure the impact of early out-of-bed mobilization of patients admitted for SAH on neuro-cardio-pulmonary physiological parameters.
