Answer:
The patient's pulse pressure is 130 - 85 = 45 mm Hg. Generally, a pulse pressure should be at least 25 percent of the systolic pressure, but not more than 100 mm Hg. Since 25 percent of 130 = 32.5, the patient's pulse pressure of 45 is normal. The patient's mean arterial pressure is 85 + 1/3 (45) = 85 + 15 = 100. Normally, the mean arterial blood pressure falls within the range of 70 - 110 mmHg, so 100 is normal.
