+### MAP (Mean Arterial Pressure)
+#### Mean Arterial Pressure or MAP is the average blood pressure within the arteries during one cardiac cycle (systole and diastole).
+#### Unit:- mmHg
+
+
+#### Parameters required:-
+| Parameters | Unit |
+| ---------- | ---- |
+| Systolic Blood Pressure | mmHg |
+| Diastolic Blood Pressure | mmHg |
+
+#### Interpretation range:-
+| Range | Interpretation |
+| ----- | -------------- |
+| <60 mmHg | Vital organs are poorly perfused |
+| 60-65 mmHg | Vital orgaans are borderline perfused |
+| 65-70 mmHg | Vital organs are adequately perfused |
+| 70-100 mmHg | Vital organs are well perfused |
+| >100 mmHg | Vital organs are hyper perfused |
+
+#### Formula:-
+$$
+\text{MAP} = \text{DBP} +  \frac{1}{3} \times\text{(SBP - DBP)}
+$$
