When your heart contracts or beats,the blood is forced through the blood vessels increasing the pressure. Thisis the highest pressure in the cycle or what is referred to as SYSTOLICBLOOD PRESSURE. In between beats, your heart relaxes and your bloodpressure decreases. This is referred to as DIASTOLIC BLOODPRESSURE.This complete series of events which occurs in a single heartbeat isknown as the CARDIAC CYCLE.Your Digital Blood Pressure Monitor will automatically read your bloodpressure and display both systolic and diastolic readings on the screen.Your systolic will be positioned as the upper number and the diastolicreading will be the lower number.(systolic) 120/80 (diastolic)Blood pressure is measured in millimeters (mm) of Mercury (Hg) and isgenerally recorded with the systolic pressure (120) listed first and thediastolic pressure (80) listed second. The numbers are typically separatedby a slash mark ( / ) as shown above.Both pressure readings, the SYSTOLIC and the DIASTOLIC, are neces-sary for a physician to evaluate the status of a patient’s blood pressure.Please contact your physician for specific information regarding your ownblood pressure.
