Hypotension is defined as a systolic blood pressure less than what value, or a drop from baseline by more than 30 mmHg?

Hypotension is defined as a systolic blood pressure less than what value, or a drop from baseline by more than 30 mmHg?

• A. 70 mm Hg
• B. 90 mm Hg
• C. 100 mm Hg
• D. 110 mm Hg

Answer: (B)

Hypotension reflects reduced perfusion to vital organs, so clinicians use an absolute threshold as a quick, reliable flag. A systolic blood pressure below ninety millimeters of mercury is the standard cut-off that indicates clinically significant hypotension requiring attention. There’s also importance to consider a large drop from a patient’s usual baseline, typically more than thirty millimeters of mercury, because a sharp decline can signify shock even if the current value isn’t below ninety—especially in patients who normally have higher baseline pressures. The other numbers don’t reliably identify those at risk, since they would misclassify many patients with poor perfusion or miss others who are deteriorating.
