ABSTRACT
Objective To explore the rat's abdominal pressure decending law by applying quantitative analytical technique.Methods Intra-abdominal hypertension rat model is made by Nitrogen aeroperitonerm.Nitrogen is exhausted the abdomen at fixed quantity and fixed time cell.MP-100A-CE type physiological monitor is used to record the changes of intra-abdominal pressure.The pressure numerical average value at different time are recorded,and the volume of Nitrogen exhausted and the pressure of intra-abdominal scatterplot are drawed.Regression analysis is used to study the functional relation between them.Results The regularity of the intra-abdominal pressure decrease was as followsIn Intra-abdominal Hypertension condition,discharge little Nitrogen could cause intra-abdominal pressure decrease greatly.Then the rate of decay is slowed.Intra-abdominal pressure(y)and Nitrogen in the abdomen(y)present decrement exponential function relation,the formula isy=36.3190?0.9769x,and the pressure-volume index is-0.01.Conclusion Regularity of intra-abdominal pressure decengding is exponential function between intra-abdominal pressure and Nitrogen volume exhausted from the abdomen.
