What is a systolic or diastolic pressure?
Systolic blood pressure is considered the maximum pressure against the arterial walls during cardiac ventricular contraction. This is the number we see on the sphygmomanometer at the first heart beat we hear while performing a blood pressure examination. Diastolic blood pressure is the number we see on sphygmomanometer on the last beat we hear. Diastolic pressure measures the minimum blood pressure occurring against the arterial walls due to ventricular relaxes. These two numbers identify the blood pressures parameters. As i mentioned earlier the normal range blood pressure readings for an adult are 120/80. Why do we need to know blood pressure? By knowing the blood pressure readings we are in able to identify heart activity, functionality, risk of diseases that might occur in the future and any possible emergency that might occur in a dental operatory. Blood pressure readings are a major factor in discovering early cardiovascular mortality that’s why dentists and dental hygienists hav
