Normal Blood Pressure

  • Systolic 100-140 mm Hg.
  • Diastolic 60-90 mm Hg.
Pulse pressure is the difference between systolic and diastolic blood pressure.
Normal pulse pressure is 30-60 mm Hg.
Mean arterial pressure is the product of cardiac output and total peripheral resistance. It is the tissue perfusion pressure.
Mean arterial pressure = Diastolic blood pressure + 1 /3 of pulse pressure.
Normal mean arterial pressure is approximately 100 mm Hg.
To confirm the presence of hypertension, multiple BP recordings should be taken with a mercurial manometer on several occasions. Home monitoring and ambulatory monitoring are preferable as they eliminate anxiety.
