Identification of Quality Measures for Performance of and Interpretation of Data From Esophageal Manometry. The catheter is then be gently removed.The catheter is gradually withdrawn to compare the pressure at the UES with that of the esophagus and throat. Finally, to test the UES, you will be asked to sit up.If peristalsis is normal, your healthcare provider will see rhythmic changes in pressure moving downward. You will take additional sips of water to measure changes in esophageal pressure as you swallow.

Doing so allows the healthcare provider to measure changes in the sphincter pressure from a closed state (before swallowing) to an open state (after swallowing).

As the catheter is withdrawn to the LES, you are asked to take several sips of water.

The sensor is set at zero to serve as the baseline for comparison.

Testing begins when the two last sensors are correctly positioned in the stomach.

At this point, you need to refrain from swallowing to ensure the calibration is correctly set.

The healthcare provider then starts to calibrate the catheter sensors.

The catheter is then taped in place and you are asked to lie on your side.

Once the catheter is past the UES, it is quickly fed into the esophagus and stomach.

Doing so opens the sphincter, allowing the catheter to enter with minimal resistance.

To move the catheter past your UES, you will be asked to sip water through a straw.

You may be asked to tilt your head down to help ease the catheter in.

As the catheter is inserted, it will reach a point of resistance as it makes an acute angle into the throat.

Before inserting the catheter, the tip is lubricated with the topical anesthetic.
