BLOOD PRESSURE MONITORING : AUTOMATED OSCILLOMETRIC DEVICES

摘要: An understanding of the principles blood pressure measurement with automated oscillometric devices (e.g., Dinamap) allows a user to realize purpose and level accuracy for which equipment is designed. Good technique calls various actions: (1) using cuff proper size (too large will generally work acceptably, but too small yield erroneously high readings); (2) squeezing all residual air out before applying it arm or leg; (3) wrapping snugly around (4) instructing patient refrain from talking moving letting nothing press against during measurement; (5) keeping heart at same horizontal level. (6) When instrument malfunction suspected, first checking status (not instrument) be sure that clinical emergency not causing suspected “malfunction”; (7) repeating reading several times when suspicious and, if necessary, modifying conditions by using, example, different limbs cuffs until question resolved; (8) remembering leak in cuff, hoses, connection can cause an unexpected malfunction.
