1. __pulse pressure_ is the calculated as systolic pressure minus diastolic pressure and indicates the additional pressure the artery when ventricles are contracting.

2. _systolic pressure_ is in the arteries at the peak of ventricular while

3. __diastolic pressure_ is the pressure in arteries during ventricular relaxation.

4. _MAP_ can be calculated as diastolic pressure plus one-third the pulse pressure because the ventricles spend more time in diastole.

5. __blood pressure_ is the force per unit area exerted a blood vessel wall by the blood, and it fluctuates with the alternating contraction and relaxation of ventricles

Explanation:

To study arterial pressure, two values are taken:

Systolic pressure, SP, is the maximum pressure exerted by the heart while beating

– Diastolic pressure, DP, is the amount of pressure in the arteries between beats

Pulse Pressure, PP, refers to the difference between systolic arterial pressure and diastolic arterial pressure.

PP = SP – DP

PP is an index of arterial distensibility. The main determinants for PP in each ventricular ejection are the cardiac output, heart rate, stiffness of large-caliber arteries, and the early reflection wave of the heartbeat. PP is a measure that reflects the vascular elasticity of the arterial wall.

Generally speaking,

• PP>40mm Hg is normal
• PP>60 mmHg is a cardiovascular disease risk factor

Mean Arterial pressure, MAP, can be defined as the mean pressure during the cardiac cycle. It is usually a little bit lower than the mean between SP and DP.

• MAP > 60 mmHg is enough to keep organs well perfused.
• MAP< 60mm Hg is a risk that certain organs will not get sufficient blood supply and it will become ischemic.

Blood pressure is the strength applied by the blood against the vessel walls as it flows.  This pressure is determined by the blood pumping force and its volume, and by the vessel size and flexibility.
