1、 EXAMINATION OFBLOOD VESSELS*1INTRODUCTIONPalpation of the pulseMeasurment of arterial blood pressureAuscultation of blood vesselsDate2PALPATION OF THE PULSERadial artery is usually selectedPatients hand placed with the palm upwardPhysicians first three fingers on the radial arteryIndex finger neare
