Formula for converting bladder pressure into intra-abdominal pressure

Measured water column height (cmH2O)/ 1.36+5mmHg.

Intra-abdominal pressure refers to the pressure in abdominal cavity, which is usually used to evaluate the severity of abdominal diseases. Bladder pressure refers to the pressure in the bladder, which is usually used to evaluate the condition of bladder function.

This formula is based on the principle of physics, that is, the density of water and the acceleration of gravity are fixed, and the intra-abdominal pressure can be calculated by measuring the height of the water column. Divide the measured water column height by 1.36 and add 5 mm Hg to get the approximate intra-abdominal pressure.
