Calculating the mean arterial pressure (MAP)

MAP, or mean arterial pressure, is defined as the average pressure in a patient’s arteries during one cardiac cycle. It is considered a better indicator of perfusion to vital organs than systolic blood pressure (SBP). True MAP can only be determined by invasive monitoring and complex calculations; however it can also be calculated using a formula of the SBP and the diastolic blood pressure (DBP).
2...the pressure exerted by the weight of the atmosphere, which at sea level has a mean value of 101,325 pascals (roughly 14.6959 pounds per square inch).
5..(2)Area over in which force acts.
The same force can produce different pressure depending upon area in which it acts.
When the force acts over a large area,the pressure produced is less.
Pressure = Force/Area
S.I. Unit of Pressure is N/m2 (or)Nm -2(pronounced Newton Metre to the power of minus two)
1Pascal = 1N/m2(Newton metre square
