Prone Positioning in ARDS: Predicting Neurological Complications Via Cerebral Hemodynamics

Who May Qualify: - Age≥18 years - Meet the diagnostic criteria for ARDS(Acute Respiratory Distress Syndrome),with PaO₂/FiO₂\<150 mmHg,and requiring prone ventilation - Expected duration of mechanical ventilation\>48 hours - Written willing to sign a consent form obtained Who Should NOT Join This Trial: - Presence of contraindications to prone positioning(e.g.,head and neck injuries,spinal instability,severe intracranial hypertension) - Severe neurological diseases(e.g.,cerebral hemorrhage,cerebral infarction,intracranial space-occupying lesions)that may affect the monitoring of cerebral hemodynamics - Life-threatening ARDS - Patients who are unable to undergo neurological assessment - Poor image quality or absence of images Always talk to your doctor about whether this trial is right for you.
