What does hypotension indicate?

Hypotension refers specifically to abnormally low blood pressure. Blood pressure readings are expressed in millimeters of mercury (mmHg) and consist of two numbers: systolic (the pressure when the heart beats) over diastolic (the pressure when the heart rests between beats). When these readings fall below a certain threshold, it is classified as hypotension. This condition can lead to various symptoms, including dizziness, fainting, and in severe cases, shock, highlighting its clinical significance.

Low blood pressure can have various causes, including dehydration, prolonged bed rest, certain medications, and medical conditions affecting the heart, among others. Understanding hypotension is crucial in clinical settings, as it requires appropriate identification and management to prevent complications.
