- Measurement ticks can be added to the tubing or cathéter to aid in identifying where the end of the tube is located. Timing for inflation can be initiated by having the tube contain a pH sensor that détermines a location différence between the esophagus (pH 5-7) and the stomach (pH 1-4) based on the différent pH between the two anatomical sources, or can be derived or verified from the expected pressure in a contained (Le., esophagus) versus a less-constrained space (Le., stomach).
