The location of blood pressure measurement significantly impacts signal quality and readings
the verdict
SUPPORTED
the evidence backs this
confidence 94/100
Evidence confirms that the anatomical location of blood pressure measurement—such as peripheral sites versus central arteries or varying positions on the upper limb—significantly affects pulse wave morphology, signal stability, and absolute pressure readings.
