May reduce observer bias in BP measurement; leaves open whether Infrasonde adoption improves hypertension outcomes.
Does an infrasonic recorder (Infrasonde) reduce observer bias in systolic blood pressure measurement compared to standard cuff-mercury sphygmomanometers in elderly hypertensive men?
The Infrasonde is a reliable alternative device for systolic blood pressure measurement that helps eliminate observer biases such as terminal digit preference associated with standard cuff recordings.
