When using the Habashi technique of Time Controlled Adaptive Ventilation (TCAV) method in the APRV mode, the release phase occurs when expiratory gas flows through the artificial airway creating a slope angle with the deceleration of gas flow. The resultant slope angle reflects the elastance of the respiratory system and provides real-time assessment of lung mechanics…

Driving Pressure in APRV Using TCAV Method
Recent data in a meta-analysis of randomized controlled trials of acute respiratory distress syndrome (ARDS) suggest that driving pressure (ΔP) may be a critical factor in outcome, with a ΔP <14 cmH2O being a better predictor of survival. Previous studies have focused on ΔP; however, little to no data exist for ΔP with the mode Airway Pressure Release Ventilation (APRV).
