KINS 2295 Lecture Notes - Brachial Artery, Stethoscope, Pressure Measurement
Document Summary
The step by step procedure for measuring blood pressure: measure the circumference of the subject"s arm to determine what size cuff to use, wrap the deflated cuff around the subject"s arm (1inch above elbow joint). Place the rubber bag over the inner arm, with arrows placed over the brachial artery to ensure proper positioning. Attach the manometer to the cuff: locate the brachial artery by gently pressing down on medial edge of the biceps tendon to feel it pulse. Phase 1: the period marked by clear, tapping sounds are present represents the systolic blood pressure. Phase 2: the period during which murmur of swishing quality is heard. Phase 3: the period during which sounds are deeper and increase in intensity. Phase 4: the period marked by the abrupt muffling of sound, where soft blowing quality is heard. When all sounds have disappeared, the cuff should be deflated rapidly and completely.
