ABSTRACT:
An esophageal gastric tube inserted through the mouth or nose into the stomach of a patient. The single tube incorporates a lumen ending in a stomach catheter to permit necessary evacuation of the stomach contents including a relief passage to admit ambient air pressure to avoid undue stomach contraction. The tube also incorporates a stethoscopic lumen with a pick-up port to be located in the heart lung area of the patient to monitor heart and lung sounds during an on-going operation.
