WebbIntraesophageal pH monitoring can be used to quantify the acidity of refluxed stomach contents, as well as the reflux index (the percentage of time that the esophageal pH is <4.0). The reflux index is a valid measure that reflects overall esophageal acid exposure. In infants, a reflux index of ≥11% is considered abnormal. Webbbe utilised: percentage total time oesophageal pH<4 <5%; percentage upright time oesophageal pH<4 <8%; percentage supine time oesophageal pH<4 <3%; number of episodes pH<4 for >5 minutes <3 (Evidence grade B).
