Ventilatory Parameters in Acute Neurological Injury

The goal of this observational study is to test the association between baseline ventilatory parameters (in particular mechanical power (MP), mechanical power normalized to predicted body weight (MP/PBW) and driving pressure (DP) with the baseline neurological status (assessed through the Glasgow coma score) in adults patients under mechanical ventilation with acute neurological injury secondary to stroke, brain trauma or subarachnoid hemorrhage. The main question\[s\]it aims to answer are: 1. In patients with acute neurological injury under mechanical ventilation, is there a correlation between the acute neurological injury, assessed using the Glasgow scale on admission, and baseline ventilatory parameters? 2. In patients with acute neurological injury under mechanical ventilation, are the baseline ventilatory parameters altered at baseline?
