The normal resting vital sign ranges for a healthy adult are a breathing rate of 12 to 18 breaths per minute, a heartbeat of 60 to 100 beats per minute, and a temperature between 97.8 to 99.1 degrees Fahrenheit, according to MedlinePlus.
Blood pressure is not considered a vital sign, but is usually measured alongside vital signs, explains Johns Hopkins Medicine. The normal blood pressure rate for a resting adult is blood pressure of 90/60 to 120/80 millimeters of mercury. Vital signs are measured to check the body's level of physical functioning. Individuals can monitor their vital signs at home, which helps doctors measure how effective certain medications are working.
