a novel disposable sensor for measure intraabdominal pressure background measurement of intraabdominal pressure iap is realized with the krons method however this technique has drawbacks like an infusion of water into the bladder of the patientobjective the prove a new novel disposable sensor in the way to measure the iap dsiap this one addresses some limitations of the kron methodmaterials and methods the dsiap was tested in vitro and clinical settings the proposed technique was compared with krons method through pearson correlation and blandaltman analysis for in vitro tests 159 measurements were taken performed by simulating the iap in the bladder for the clinical test 20 pairs of measurements were made in patients with routine iap monitoring in the intensive care unitresults in vitro measurements showed a strong correlation between the dsiap and the reference r 099 pvalue 22 1016 the bias and 95 confidence intervals were 0135 and 08211091 cmh2o respectively measurements in patients with dsiap versus krons method shown a very good correlation r 0973 pvalue 546 1013 while the bias and confidence intervals were 0018 and 34613496 mmhg respectivelyconclusions the results suggest that the proposed dsiap showed a profile similar to pressure transducers already in clinical use while overcoming some limitations of the former
