What is the medical definition of hypotension?

The medical definition of hypotension refers to abnormally low blood pressure, which is typically characterized by a specific threshold measured by both systolic and diastolic blood pressure. The correct choice indicates that hypotension is defined as a systolic pressure below 90 mmHg and a diastolic pressure below 60 mmHg. This definition aligns with clinical guidelines used in medicine to diagnose hypotension, as it recognizes both components of blood pressure.

When blood pressure readings fall below these levels, it can indicate that the body's organs may not be receiving adequate blood flow, which can lead to symptoms like dizziness, fainting, or shock. This threshold helps healthcare providers identify when intervention may be necessary to manage a patient's blood pressure effectively.

Options regarding systolic pressure alone, such as below 80 mmHg or below 100 mmHg, do not encompass the complete clinical picture of hypotension, as diastolic pressure also plays a crucial role in determining the overall blood pressure status. Additionally, solely relying on diastolic pressure levels does not provide a comprehensive definition of hypotension, thus missing the critical aspect of assessing both systolic and diastolic measurements.
