Which condition is defined as 'hypotensive' for adults?

Hypotension in adults is generally defined as having a systolic blood pressure (SBP) of less than 90 mmHg. This threshold is significant because it indicates inadequate perfusion of vital organs and may lead to shock if not addressed promptly.

A systolic blood pressure below this level can be concerning and often prompts further evaluation and intervention. While some texts might reference a threshold of 80 mmHg for specific patient populations or situations, the most widely accepted standard for defining hypotension in adults is below 90 mmHg. Hence, the definition provided aligns with current clinical practice guidelines that prioritize patient safety and effective treatment strategies.
