The normal range for an adult resting heart rate is established based on extensive physiological research and clinical observations. An adult at rest typically has a heart rate that falls between 60 to 100 beats per minute.

This range reflects the average cardiac output required to meet the body's metabolic needs while in a state of rest and is influenced by various factors, including age, fitness level, and autonomic nervous system balance. Individuals who are physically fit, such as athletes, may have resting heart rates below this range, but for the general adult population, the 60 to 100 beats per minute range is considered normal.

Heart rates below 60 beats per minute may indicate bradycardia, which can be normal in well-trained individuals or may indicate a medical condition requiring further evaluation. Conversely, heart rates above 100 beats per minute at rest are considered tachycardia, which can be associated with stress, anxiety, dehydration, or underlying medical conditions.

This established range is critical for paramedics and healthcare providers as a vital sign to assess a patient's overall cardiovascular health and to identify any potential health issues that may need to be addressed.
