Conversely, the oxygenation index and blood pH showed a decreasing trend (all P < 0.001).

Trend analysis showed that as mechanical power increased, PaO2, PaCO2, serum creatinine, blood urea nitrogen, potassium, hemoglobin, white blood cell count, respiratory rate, minute ventilation, tidal volume, plateau pressure, PEEP, oxygen concentration, and peak airway pressure all showed an increasing trend.
