A comparison of differential oscillometric device with invasive mean arterial blood pressure monitoring in intensive care patients

Abstract

Non-invasive beat-to-beat mean arterial pressure (MAP) in finger arteries recorded by the differential oscillometric device was compared with MAP recorded invasively from A. radialis in 22 patients after cardiac surgery. Based on all 132 paired measurements, the MAP values measured at the radial artery were 2.7 ± 4.9 mmHg higher than those measured on fingers. Among 22 patients there were 8 patients receiving inotropic support, their difference being 2.1 ± 5.6 mmHg. The present study revealed that the mean discrepancy between the invasive radial pressure and finger pressure was small; however, patient data sets showed marked variability in average pressure differences when examined individually.

Noninvasive Techniques for Blood Pressure Measurement Are Not a Reliable Alternative to Direct Measurement: A Randomized Crossover Trial in ICU

“…However, several studies found that BP measurement in the brachial artery by both intra-arterial and auscultatory methods provided different results [27]. Moreover, comparisons of radial IBP with wrist or finger OBP did not produce uniform results, as expected [19, 22, 23, 33]. Unfortunately, in clinical practice decisions are often based on the BP values that are available, regardless of the method (NIBP or IBP) or the site (radial or brachial artery) where BP is detected.…”

“…This may result in greater risks of erroneous clinical decisions—for example, unnecessary use of inotropic support and blood transfusions in hypotensive patients or, conversely, delayed antihypertensive treatment in hypertensive patients [13, 19, 28]. Unfortunately, the literature is not consistent about the range of accuracy that can be considered acceptable in critically ill patients.…”

Accuracy and Precision of Continuous Noninvasive Arterial Pressure Monitoring Compared with Invasive Arterial Pressure

“…Thirteen articles [25][26][27][28][29][30][31][32][33][34][35][36][37] were excluded after full-text review for failure to meet the inclusion criteria or insufficient data for meta-analysis (appendix 3). The remaining 28 studies [8][9][10][11][12][13][14][15][16][17][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54][55] were included in the systematic review (fig. 1).…”

Mean Arterial Blood Pressure Monitoring Among Pediatric Patients after Open Heart Surgery

“…This tool was developed by the researchers after reviewing the related literature (16)(17)(18)(19)(20)(21)(22) . The tool was utilized to assess definite items related to MAP.…”
