Choosing a blood pressure machine from their ever increasing number is often difficult due to lack of performance data. We have evaluated a new automated non-invasive blood pressure recorder, the Infrasonde D4000. In comparison with the Hawksley random zero mercury sphygmomanometer the Infrasonde showed less variability for both systolic and diastolic readings. However, it was found to record significantly lower mean systolic and diastolic pressures.
由于缺乏性能数据,从数量不断增加的血压计中选择一款往往很困难。我们评估了一种新型自动无创血压记录仪——Infrasonde D4000。与Hawksley随机零汞血压计相比,Infrasonde在收缩压和舒张压读数方面的变异性更小。然而,发现它记录的平均收缩压和舒张压明显更低。
