Summary

The purpose of this study is to understand the relationship between intracranial pressure and airway pressures during mechanical ventilation. This study is a single-center, prospective cohort study to be conducted at Beth Israel Deaconess Medical Center. The investigators will recruit patients with severe brain injury (GCS 8 or less) who receive intracranial pressure monitoring and mechanical ventilation as part of their routine medical care. The primary endpoint is the change in intracranial pressure as a function of positive end-expiratory pressure. There is only one study encounter with safety monitoring for up to 24 hours after. No additional follow up is required.

PEEP Titrated Mechanical Ventilation

Subjects will receive a sequential, step-wise increase in positive end-expired pressure from 5 cmH2O to 15 cmH2O and back down to 5 cmH20. Pleural pressure and intracranial pressure will be measured at each increment. PEEP will be increased by increments of 5 cmH2O. The physiologic measurements will be obtained at regular intervals (within 5 minutes at each PEEP level) throughout the PEEP titration period. The mode of mechanical ventilation (pressure or volume control), inspiratory time and fraction of inspired oxygen (FIO2) will be determined by the critical care team caring for the patient. In the event that PEEP is set \> 5 cmH2O, measurements will be obtained from that starting point and increased to a maximum of 15 cmH2O. At the completion of the study patients will be returned to the PEEP level they were on prior to titration of the ventilator.
