What is the normal systolic blood pressure range for adults?

The normal systolic blood pressure range for adults is generally considered to be between 90 and 140 mmHg. This range represents a typical healthy blood pressure reading for adults. Blood pressure readings outside this range can indicate potential health issues; for instance, a systolic reading below 90 mmHg may suggest hypotension, while a reading above 140 mmHg may be indicative of hypertension.

In medical practice, blood pressure readings are often expressed in millimeters of mercury (mmHg), with systolic pressure being the higher number, representing the pressure in the arteries when the heart beats. The range of 90-140 mmHg captures the variation typically observed in healthy adults, accounting for differences due to factors like age, gender, fitness level, and overall health.

Understanding these ranges is critical for outdoor emergency care technicians, as recognizing abnormal blood pressure readings can help assess the condition of patients in emergency situations and guide further medical decisions.
