You have high blood pressure if readings average140/90 or higher -- for either number -- though you may still have no symptoms. At 180/110 and higher, you may be having a hypertensive crisis. Rest for a few minutes and take your blood pressure again. If it is still very high, call 911. A hypertensive crisis can lead to a stroke, heart attack, kidney damage, or loss of consciousness. Symptoms of a hypertensive crisis can include a severe headache, anxiety, nosebleeds, and feeling short of breath.
Systolic pressure measures blood pressure as the heart contracts and pushes blood through the arteries. Diastolic pressure is taken when the heart relaxes. Normal blood pressure is around 120/80 or lower. It is important to note that blood pressure varies from person to person and can fluctuate from moment to moment. One or two high readings does not necessarily mean that you have hypertension or high blood pressure.
