Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of intraarterial with continuous noninvasive blood pressure measurement in postoperative pediatric patients.
The purpose of this study was to estimate the accuracy, bias, and frequency response of continuous blood pressure monitoring using finger photoplethysmography in children. ⋯ Substantial measurement bias exits between this noninvasive blood pressure measurement technique and intraarterial blood pressure. Measurements of the intrapatient variability and frequency response analysis suggest that the noninvasive technique accurately tracks intraarterial blood pressure over the short term. This technique may have useful applications in settings where intraarterial monitoring is undersirable or unobtainable.
