Exploration of the Appropriate Combination of Positive End Expiratory Pressure and Tidal Volume Using the Intratidal Compliance Volume Profile in Children

Exploration of the Appropriate Combination of Positive End Expiratory Pressure and Tidal Volume Using the Intratidal Compliance-volume Profile in Children

In children under 6 years of age undergoing regular surgery during general anesthesia, the intratidal compliance profile is evaluated when different tidal volumes are applied at different positive end expiratory pressures.

Then determine the most appropriate combination of positive end-tidal pressure and tidal volume.

Inclusion Criteria:

• Children undergoing surgery > 1 hour under general anesthesia

• American society of anesthesiology physical status I, II

Exclusion Criteria:

• Previous lung surgery
• Bronchopulmonary dysplasia, respiratory distress syndrome
• Other interstitial lung disease
• Laparoscopic surgery
• Thoracic surgery, abdominal surgery
