Automated Versus Manual Occlusion Pressure at 100 ms With Hamilton C6 Using the Software Version 1.2.3: From Bedside to the Bench and Back to Bedside

Objectives

Occlusion pressure at 100 ms after the start of inspiratory effort (P 0.1 ) is a marker of respiratory drive and a predictor of weaning outcomes in mechanically ventilated patients. Some ventilators, like the Hamilton C6 (Hamilton Medical AG, Bonaduz, Switzerland), estimate P 0.1 automatically (P 0.1vent ) without performing an actual airway occlusion, potentially leading to inaccuracies.
