When to Use. The dynamic compliance (C DYN) of the lung model for each group was calculated as follows: C DYN = Vt/ (peak airway pressure positive end-expiratory pressure [PEEP]) ( Tables 1 and 2 ). Oxygen consumption varied directly with Vt and inversely with compliance, increasing from 4.8 +/- 0.07 L/min with the HC-500 mL Vt model to 6.2 +/- 0.05 L/min Range: 2 to 6 l/min. Did someone say, "5 of PEEP?" In order to better solve the phenomenon of low oxygen in the corner of return airway caused by abnormal gas emission in goaf during shallow coal seam mining, by analyzing the source and reason of low oxygen phenomenon, a prediction model of oxygen concentration in the corner of return airway based on genetic algorithm (GA) and random forest (RF) technology was proposed.
