After allowing a brief period for patient acclimation to the catheter, a baseline of resting pressures is obtained during at least 30 s of restful breathing devoid of swallows. This allows for evaluation of the resting EGJ pressure and EGJ morphology. At the conclusion of the baseline testing period, we have the patient take three deep breaths to aid in the evaluation of the EGJ morphology (Figure 8.1).
