- The patient positioned supine and in a 30° head of bed angle. IBP, intra-bladder pressure; LIAP, lower intra-abdominal pressure; UIAP, upper intra-abdominal pressure; HOB, head of bed, IAP, intra-abdominal pressure; COVA; coefficient of variance; LLA, Lower level of agreement; ULA, Upper level of agreement. a
r = Pearson product-moment correlation coefficient.
