The danger zone for blood pressure is a reading of 180/120 millimeters of mercury (mm Hg) or greater. This level indicates a hypertensive crisis, which is a medical emergency.
Understanding Hypertensive Crisis
A hypertensive crisis is when blood pressure rises rapidly and severely. It can lead to serious and life-threatening complications. According to the Mayo Clinic, blood pressure at or above 180/120 mm Hg requires immediate medical attention.
Why is a Hypertensive Crisis Dangerous?
Such high blood pressure places an extreme strain on blood vessels and organs. This can cause:
- Heart Attack: The intense pressure can damage heart tissue and block blood flow.
- Stroke: High pressure can cause blood vessels in the brain to rupture or become blocked.
- Other Health Problems: Can also lead to kidney damage, vision loss, and other organ damage.
What to Do if Blood Pressure is in the Danger Zone
If you or someone you know has a blood pressure reading of 180/120 mm Hg or higher:
- Seek Emergency Medical Help Immediately: Call emergency services or go to the nearest hospital as soon as possible.
- Do not try to self-treat: The situation requires professional medical evaluation and intervention.
- Be aware of Symptoms: Be aware of potential symptoms, which can include severe headache, dizziness, chest pain, difficulty breathing and visual changes.
