pH Probe

November 10th Tye will have one more test called a pH probe that the surgeon requested. He will be admitted to the hospital for 24 hours.

This is pasted in from the internet to describe a pH probe study.

A pH probe study is a test done to find out if acid from the stomach is coming up into the esophagus (food tube).
In this test, a thin, flexible tube is passed through the nose, down the back of the throat, and into the esophagus. The tube is carefully taped in place. The end of the tube is attached to a small recording machine. This recorder has a belt that may be buckled around your child's waist or carried over a shoulder.
A pH probe study takes 18 to 24 hours. The tube is left in place for this time. You will be asked to keep a diary of your child's activity during the study. The doctor will use the diary to compare the computer reading with your child's activity.

I am still not convinced that this will tell us any more information than what we have. I will be calling the GI tomorrow to get a little more information. It's my understanding that Tye needs the surgery because he is aspirating. This test will measure how many times he is refluxing but has nothing to do with the lungs and how ofter he aspirates:(

Tye's surgery is tentatively scheduled for either December 4th or December 11th.
