Accuracy of esophageal pressure measured by an air-filled esophageal balloon catheter is dependent on balloon filling volume. However, this has been understudied in mechanically ventilated children. We sought to study the optimal filling volume in children receiving ventilation by using previously reported calibration methods. Secondary objectives included to examine the difference in pressure measurements at individualized optimal filling volume versus a standardized inflation volume and to study if a static hold during calibration is required to identify the optimal filling volume.

机械通气儿童最佳食管导管球囊充气量的评估。

充气食管球囊导管测量的食管压力的准确性取决于球囊填充量。然而，这在机械通气儿童中尚未得到充分研究。我们试图通过使用先前报道的校准方法来研究接受通气的儿童的最佳充盈量。次要目标包括检查个性化最佳填充体积与标准化充气体积的压力测量值的差异，并研究校准期间是否需要静态保持来确定最佳填充体积。
