What vital sign indicates severe hypotension in Sandra Harris?

The vital sign that indicates severe hypotension is represented by a blood pressure reading of 60/30. This measurement reflects a critically low systolic pressure (60 mmHg) and a diastolic pressure (30 mmHg), leading to a very narrow pulse pressure. In such a scenario, the body is unable to maintain adequate blood perfusion to vital organs, which can result in symptoms such as confusion, dizziness, and even loss of consciousness.

Understanding blood pressure readings is crucial, as a systolic pressure below 90 mmHg is generally considered hypotensive, and levels significantly lower, like 60, indicate low perfusion pressure and potential shock. This presents a medical emergency as the body's systems may start to fail without immediate intervention to stabilize blood pressure and restore blood flow to essential organs.
