The diagnosis of hypotension is made by first obtaining a blood pressure, either non-invasively with a sphygmomanometer or invasively with an arterial catheter (mostly in an intensive care setting). If the systolic blood pressure is <90mmHg or the diastolic blood pressure is <60mmHg, it would be classified as hypotension. Another way to measure low blood pressure is the MAP (Mean Arterial Pressure) using the arterial catheter or continuous, non-invasive hemodynamic monitoring which measures intra-operative blood pressure beat-by-beat throughout surgery. A MAP <65mmHg is considered hypotension. Intra-operative hypotension <65 mmHg can lead to an increased risk of acute kidney injury, myocardial injury or post-operative stroke. For most adults, the ideal blood pressure is at or below 120/80 mmHg. A small drop in blood pressure, even as little as 20 mmHg, can result in transient hypotension. Orthostatic vitals are measured to diagnose orthostatic hypotension. Evaluation of vasovagal syncope is done with a tilt table test. Besides the definitive threshold, an abrupt fall in systolic blood pressure around 30 mmHg from one's typical average systolic pressure can also be diagnosed with hypotension.
