A Novel Method (CiMON) for Continuous Intra-Abdominal Pressure Monitoring: Pilot Test in a Pig Model

Table 2

Statistics of comparison between different device readings in the 25° head-up elevation position.

Device	Bias (mmHg)	Precision (mmHg)	Limits of agreement (mmHg)	Percentage error
IAPCiM−IAPspie	−1.1	1.1	−3.2to1.0	11.0
IAPCiM−IAPdir	−0.5	2.7	−5.8to4.8	26.3
IAPCiM−IAPivp	−1.0	2.2	−5.4to3.3	19.9

Mean difference between different device readings (bias), precision (standard deviation), percentage error (%), and limits of agreement in the 25° head-up elevation position. CiMON balloon-tipped catheter pressure (IAP_CiM), Spiegelberg balloon-tipped catheter pressure (IAP_spie), direct intraperitoneal pressure (IAP_dir), and intravesical pressure (IAP_ivp) measurement.
