Blood Pressure Monitoring

Aug. 2012. 1. DETERMINATION OF BLOOD PRESSURE AIM To record and present the systolic and diastolic BP using Sphygmomanometer. PRINCIPLE The stripe of the sphygmomanometer is disguised around the arm of the subject. The home is thence inflated until the root of merchandise rack in the cuff overcomes the arterial pressure and obliterates the arterial lumen. This is confirmed by palpating the radial pulse that disappears when the cuff-pressure is raised supra the arterial pressure. The pressure is then raised further by 20 mm Hg and then slowly reduced. When the pressure in the cuff reaches incisively below the arterial pressure, agate line escapes beyond the occlusion in to the peripheral part of the arterial blood vessel and the pulse starts reappearing. This is detected by the appearance of function perceive in the stethoscope and pressure at which the impenetrables are first hear is the systolic pressure. Subsequently, the quality of the sound changes as the pressure is lowered, the sounds become louder and then dull and deadening and finally, disappear. These are sounds of Korotkoff. The sounds of Korotkof are produced out-of-pocket to turbulent flow in the partially constricted brachial artery. The level where sound disappears is taken as the diastolic pressure. The sound disappears because the flow in the blood vessels becomes laminar.

Requirements: Sphygmomanometer, stethoscope and a chair or couch. Description of sphygmomanometer: It consists of an inflatable golosh cuff (Riva-Rocci cuff) attached by two pipes. One tube connects the bag to a hectogram manometer and the other tube c! onnected to a hand medulla ( pencil eraser pump) fitted with a valve which may be used for inflating or deflating the rubber cuff. Width of the cuff should be 20% more than the diam of the arm. For adults, width of the cuff should be 12.5cm, for children below 8 bulky time 8cm, below 5 years 5cm and for infants below 1 year is 2.5cm.
