Document Summary

* palpation = measuring blood pressure at the wrist waiting to feel heart beat. * auscultation = measuring blood pressure using a stethoscope at the elbow region = same level of heart. The palpation method - blood has to travel all the way to the wrist to be detected, more blood flow needed and cuff needs to be released more to get pulse at wrist. * auscultation would give a higher value for systolic blood pressure takes longer for blood to go from the elbow to the wrist so the measurement is taken later. * you (cid:272)a(cid:374)"t get a diastoli(cid:272) (cid:271)lood pressure fro(cid:373) the palpatio(cid:374) (cid:373)ethod, but you can get diastolic and systolic blood pressure from the auscultation method. * we can hear sounds when there is turbulent flow blood flow has been partially blocked. As the pressure decreases and falls between 90-
