Answer: To increase arterial pressure you need to increase the cardiac output
Explanation:
Cardiac output is the volume of blood being pumped by the heart in one minute. It is equal to heart rate multiplied by stroke volume.
Two factors affect the strength of the blood: cardiac output and peripheral resistance. Cardiac output is the volume of blood circulated by the heart. Increasing heart rate also results in increased cardiac output, which increases blood pressure.
