Why do automatic blood pressure machines read high?

Why do monitors read high? If you have ever used an automated monitor to measure blood pressure, you probably have encountered a reading you thought was too high. First, the longer a patient sits waiting for BP measurements to be taken, the more likely it is that BP is stabilized to its resting level.

What is the dangerous level of high blood pressure?

Danger zone A blood pressure reading above 180/120 mm Hg indicates a serious health problem. The AHA refers to these high measurements as a “hypertensive crisis.” Blood pressure in this range requires urgent treatment even if there are no accompanying symptoms.

What is classed as low blood pressure?

Most doctors consider blood pressure too low only if it causes symptoms. Some experts define low blood pressure as readings lower than 90 mm Hg systolic or 60 mm Hg diastolic. If either number is below that, your pressure is lower than normal. A sudden fall in blood pressure can be dangerous.

What is considered high blood pressure?
