The Value of End-tidal Capnography in Gastrointestinal Bleeding

Gastrointestinal bleeding is a condition that frequently presents to emergency departments and can be fatal if diagnosis and treatment are delayed. The working mechanism of end tidal capnography is simply to detect the respiratory carbon dioxide level. In our study, the investigators aimed to determine the severity of gastrointestinal bleeding by using the Glaskow Blachford Score and AIMS65 score in cases presenting with gastrointestinal bleeding, to determine the end tidal carbon dioxide value by capnography in these cases and to determine its effectiveness in evaluating mortality and morbidity in gastrointestinal bleeding.
