The oscillometric ambulatory blood pressure recorder Daypress 500 was validated according to the British Hypertension Society protocol. Both sequential and simultaneous measurements were used. Multiple regression analysis demonstrated a significant influence of subject pulse pressure and arm circumference on device-observer systolic pressure differences. Differences between observer consecutive readings were inversely related to heart rate. Device and observer blood pressure readings were closer at simultaneous than at sequential measurements. However, both kinds of measurement led to the same final evaluation (A for diastolic and B for systolic blood pressure), provided that the appropriate grading criteria were applied for each method.
示波法动态血压记录仪Daypress 500已按照英国高血压学会的方案进行了验证。采用了连续测量和同步测量两种方法。多元回归分析表明，受试者的脉压和上臂围对设备与观察者之间的收缩压差值有显著影响。观察者连续读数之间的差异与心率呈负相关。同步测量时设备与观察者的血压读数比连续测量时更接近。然而，只要对每种方法应用适当的分级标准，两种测量方法最终都会得出相同的评估结果（舒张压为A，收缩压为B）。
