• Esophageal manometry is a test used to measure the functionality of muscles of the esophagus(food pipe). 
• Manometry is indicated in people who have pain or difficulty in swallowing, heartburn, bringing food back up and chest pain.
• A flexible tube will be inserted through your nose, down your esophagus, and into your stomach. 
• You may have to swallow a small amount of water to help assesses how well the sphincter and muscles are working.
• For pH monitoring a thin, narrow tube with a sensor on the end that detects acid is passed softly through your nose into the food pipe and is held about 2 inches above the lower esophageal sphincter.
• The tube that comes out of your nose is attached to a recording device that is portable and can be worn on your belt or over your shoulder.
• You are expected to continue all the routine activities and press the appropriate buttons on your recorder during activities, as instructed by your nurse practitioner.
