Implementation of Neuro Lung Protective Ventilation "NEUROVENT"

Phase N/A Results N/A

Trial Description

Patients who experience lung injury are often placed on a ventilator to help them heal; however, if the ventilator volume settings are too high, it can cause additional lung injury. It is proven that using lower ventilator volume settings improves outcomes. In patients with acute brain injury, it is proven that maintaining a normal partial pressure of carbon dioxide in the arterial blood improves outcomes. Mechanical ventilator settings with higher volumes and higher breathing rates are sometimes required to maintain a normal partial pressure of carbon dioxide. These 2 goals of mechanical ventilation, using lower volumes to prevent additional lung injury but maintaining a normal partial pressure of carbon dioxide, are both important for patients with acute brain injury. The investigators have designed a computerized ventilator protocol in iCentra that matches the current standard of care for mechanical ventilation of patients with acute brain injury by targeting a normal partial pressure of carbon dioxide with the lowest ventilator volume required.
This is a quality improvement study with the purpose of observing and measuring the effects of implementation of a standard of care mechanical ventilation protocol for patients with acute brain injury in the iCentra electronic medical record system at Intermountain Medical Center. We hypothesize that implementation of a standardized neuro lung protective ventilation protocol will be feasible, will achieve a target normal partial pressure of carbon dioxide, will decrease tidal volumes toward the target 6 mL/kg predicted body weight, and will improve outcomes.

Conditions

Interventions

  • Lung Protective Ventilation Procedure
    Intervention Desc: Neuro lung protective ventilation for patients with acute brain injury is designed to target a normal partial pressure of arterial carbon dioxide and decrease initial tidal volumes toward a target 6 ml/kg predicted body weight PBW (range 6 to 8 ml/kg PBW)
    ARM 1: Kind: Experimental
    Label: Lung Protective Ventilation
    Description: Subjects with acute brain injury (traumatic brain injury and non-traumatic brain injury) will receive neuro lung protective ventilation which targets a normal arterial partial pressure of carbon dioxide with the lowest tidal volume possible (6 to 8 ml/kg predicted body weight). Protocols for oxygenation and weaning from the ventilator will also be followed.
