Lung ultrasound score evaluation of the effect of pressure-controlled ventilation volume-guaranteed on patients undergoing laparoscopic-assisted radical gastrectomy

Figure 1 Comparison of lung ultrasound scores. A-H: Changes in lung ultrasound scores of the (A) whole, (B) anterior, (C) lateral, (D) posterior, (E) upper, (F) lower, (G) left, and (H) right lung regions across time points. ^aP < 0.05 and ^bP < 0.01, compared with T0; ^cP < 0.05, vs control group.
