Sizing the lung of mechanically ventilated patients

Sizing the lung of mechanically ventilated patients. Critical Care 2011, 15:R60

Mattingley, J.S., et al


This small observational study was motivated by our belief that scaling the tidal volume in mechanically ventilated patients to the size of the injured lung is safer and more "physiologic" than scaling it to predicted body weight, i.e. its size before it was injured. We defined Total Lung Capacity (TLC) as the thoracic gas volume at an airway pressure of 40 cm H2O and tested if TLC could be inferred from the volume of gas that enters the lungs during a brief "recruitment" maneuver.
