ARDS | Acute respiratory distress syndrome |
HU | Hounsfield units |
EI | End-inspiratory |
EE | End-expiratory |
Warping | Image processing methodology to register (superimpose) anatomical structures between scans |
Severe injury | Lung tissue with irreversibly low gas content (ie, density >−300 HU) |
Unstable inflation | Lung tissue with elevated changes in EI/EE gas content and with high risk of worsening injury (ie, increasing density) at later times |
PRM | Parametric response map |
ROC | Receiver operating characteristic |
VT | Tidal volume |
PEEP | Positive end-expiratory pressure |
Cdyn | Dynamic compliance |
PIP | Peak inspiratory pressure |
