What is the upper limit of normal blood pressure?

The correct upper limit of normal blood pressure is defined as 130/80 mmHg. Blood pressure is categorized into various levels: normal, elevated, hypertension stage 1, and hypertension stage 2.

According to the American College of Cardiology/American Heart Association guidelines, normal blood pressure is classified as anything below 120/80 mmHg. Elevated blood pressure ranges from 120-129 systolic and less than 80 diastolic. Hypertension stage 1 begins at 130/80 mmHg and continues up to 139/89 mmHg. The definition of hypertension stage 2 starts at 140/90 mmHg and above.

Thus, stating that the upper limit of normal blood pressure is 140/90 mmHg does not accurately reflect the most current guidelines since readings at this level are already categorized as hypertension stage 1. Understanding these classifications is crucial for appropriate patient assessment and management in oral and maxillofacial surgery contexts, where managing a patient’s systemic health, including blood pressure, is key to ensuring safe surgical procedures.
