Table 2 PaO2 (mmHg)

From: Comparative study between volume-controlled ventilation and pressure-controlled ventilation in prevention of postoperative pulmonary atelectasis in morbidly obese patients undergoing laparoscopic gastric sleeve surgery

PaO2 Group (V), VCV (n = 26) Group (P), PCV (n = 26) t test p value
Preoperative 86.53 ± 10.21 86.86 ± 8.41 1.316 0.134
Intraoperative 212.75 ± 20.13 225.85 ± 18.69 4.638 0.011*
30 min after extubation 82.52 ± 8.16 86.60 ± 14.42 0.823 0.346
12 h after extubation 86.55 ± 7.82 83.06 ± 14.24 1.108 0.272
24 h after extubation 87.76 ± 9.12 82.83 ± 13.93 1.176 0.166
  1. This table shows statistically significant increase in intraoperative arterial oxygen tension (PaO2) in the PCV group compared to the VCV group
  2. t independent sample t test, PCV pressure-controlled ventilation, VCV volume-controlled ventilation
  3. p value > 0.05 NS, *p value < 0.05 S
