How Respiratory Mechanics Shapes Ventilator Settings and Outcomes in Acute Brain Injury Patients
Highlight
- Respiratory system elastance (ERS) significantly modifies how tidal volume (VT) and respiratory rate influence clinical outcomes in acute brain injury patients on mechanical ventilation.
- Higher VT is linked to lower ICU mortality in patients with low ERS, but this benefit dissipates in those with high ERS.
- An increased respiratory rate correlates with worse outcomes, particularly at low ERS; this association weakens as elastance increases.
- Optimal ventilator settings should balance driving pressure (ΔP) and respiratory rate to maintain adequate alveolar ventilation while minimizing harm.
