Objective: Use cuff manometry to measure arterial blood pressure. Questions: 1. My blood pressure for this lab was 123/78. These numbers are normal‚ compared to the normal rating of 120/80. My pulse pressure was 45 (SP – DP). My mean arterial pressure was 93 (DP + 1/3 (SP – DP). 2. Mean arterial blood pressure is determined by cardiac output and total vascular resistance. The mathematical equation for mean arterial blood pressure is equal to cardiac output x total vascular resistance. The amount
