Fraction of inspired oxygen (FiO₂) was titrated to maintain peripheral oxygen saturation (SpO₂) between 88% and 92%. Subsequently, PEEP was increased in 5 cmH₂O increments every 10-20 minutes from the initial value of 5 cmH₂O. Once PEEP reached 20 cmH₂O or above, increments were made every 3-5 minutes until the recruitment level was achieved (i.e., PEEP was increased stepwise from 5 to 10, 15, 20, 25, and 30 cmH₂O).
