Continuous Blood Pressure Measurement

摘要: Cuff blood pressure measurement has changed very little since the beginning of this century and provided an immense amount valuable data on outcome risk. Restrictions technique make it limited value in sleep, exercise or at work, although there are now devices which inflate deflate automatically. Perhaps biggest problem is alerting defence reaction engendered by observer even cuff inflation with automatic devices. For reason have been many attempts to develop systems track non invasively. We used pulse wave velocity follow beat changes (1). This similar not so far proved adequate for ambulatory use, all indirect severe problems calibration validation.
