• Pulse sounds


  Sounds in brachial artery
• Systolic blood pressure


  Upper value, greatest amount of pressure in arteries, contraction of ventricles, ventricular systole, force blood in arteries
• Diastolic blood pressure


  Lower value, lowest amount of pressure in arteries, relaxation of ventricles, ventricular diastole
• Unit of blood pressure


  mm in mercury
• Systolic BP value


  • 90-140 mm
• Diastolic BP value


  • 60-90 mm
• Equipment used

  • Stethoscope, sphygmomanometer
• Measuring blood pressure

  1. Cuff around arm above elbow

  2. Stethoscope under cuff at brachial artery

  3. Inflate to 180 mm

  4. Listen for pulse

  5. Record 1st beat = systolic BP

  6. Record 1st point where pulse is no longer heard = diastolic BP

  7. Record: lying, sitting, standing, after exercise
• 1st heart sound


  Lub, low-pitched, closing of auriculo-ventricular valve, ventricular systole
• 2nd heart sound


  Dub, high-pitched, closing of semilunar valves, ventricular diastole
• Place stethoscope at heart apex, between 5th & 6th rib, slightly to the left
