Measuring the air pressure of the stomach duct in the stomach and in the trachea using a water bottle to prevent misplacing / 中国康复理论与实践

ABSTRACT

@# ObjectiveTo research a way to verify whether the stomach duct is misplaced into the trachea.MethodsThe air pressure of the stomach duct placed in the stomach or in the trachea were measured using a water bottle.ResultsThe air pressure of the stomach duct was (1±0.45)cmH2O When it was put in the stomach, and was (7±2.03)cmH2O when it was put in the trachea(P<0.01).ConclusionsWhen it is impossible to draw out acerbic substances from the stomach to verify whether the stomach duct is placed in the stomach or misplaced in the trachea, measure the air pressure stomach duct by a water bottle can be used as substitute, which is reliable and convenient.
