To evaluate blood pressure (BP) and pulse rate (PR) measurement range and determination time of selected non-invasive blood pressure (NIBP) monitors.
Seven oscillometric NIBP monitors underwent laboratory-based simulations of high and low BP and PR values to determine the outer bounds that each monitor could measure. Reliability was determined by devices' ability to detect simulation signals of chosen BP/PR values. Determination times were analyzed using One-Way ANOVA followed by post-hoc Tukey honestly significant difference.
All monitors reliably reported 50-180 mmHg and 80-140 bpm simulations, except Connex which provided the narrowest ranges (only reliable at 140 and 230 bpm; 50-180 mmHg). B125 and Efficia CM120 had the widest ranges for PR (30-240 bpm and 30-220 bpm, respectively) and systolic BP (30-250 mmHg for both). Connex presented the quickest mean determination time (19.23s), followed by B125 (24.14s).
NIBP monitor performances varied considerably outside mid-range BP/PR and there were significant differences across determination times. NIBP devices that strike a balance between range and speed may provide the greatest clinical utility.
评估选定的无创血压（NIBP）监测仪的血压（BP）和脉搏率（PR）测量范围及测定时间。
七台示波法NIBP监测仪进行了基于实验室的高低血压及脉搏率值模拟，以确定各监测仪能够测量的范围边界。通过设备检测选定血压/脉搏率值模拟信号的能力来确定可靠性。使用单因素方差分析及事后检验的Tukey真实显著差异法分析测定时间。
除Connex监测仪提供的范围最窄（仅在140和230 bpm可靠；50 - 180 mmHg）外，所有监测仪均能可靠报告50 - 180 mmHg和80 - 140 bpm的模拟值。B125和Efficia CM120的脉搏率测量范围最宽（分别为30 - 240 bpm和30 - 220 bpm），收缩压测量范围也最宽（均为30 - 250 mmHg）。Connex的平均测定时间最短（19.23秒），其次是B125（24.14秒）。
在血压/脉搏率范围的中间值以外，NIBP监测仪的性能差异很大，测定时间也存在显著差异。在范围和速度之间取得平衡的NIBP设备可能具有最大的临床实用性。
