Ventilator Settings on Patients With Acute Brain Injury
Relation Between Lung Protective Mechanical Ventilation, Intracranial Pressure, Autoregulation and Brain Oxygenation in Neurointensive Care Patients
Studieoversigt

Intervention / Behandling
Detaljeret beskrivelse
The primary goal is to carry out baseline measurements to enable conclusions concerning the safety of lung protective ventilator settings before extending the study to patients with more severe brain and/or lung injury in the future.
The primary objective is to investigate if lung protective ventilator settings (higher Positive end-expiratory pressure and lower tidal volume) as compared with conventional settings.
- increase intracranial pressure
- diminish cerebral vasoreactive autoregulation as assessed by pressure reactivity index, ie pressure reactivity index will turn positive, which means that it will change the state from intact to impaired autoregulation.
The secondary objective is an exploratory analysis of the relationship between ventilator settings and other well defined respiratory, cerebral, and cardiovascular variables, including transpulmonary pressure.
