Arterial pressure results from the pressure exerted by the blood in the large arteries. Blood pressure depends on cardiac output and total peripheral resistance. Arterial pressure fluctuates with each heart beat, according to the pumping of the heart.
Moreover, a graphic display of arterial pressure can be viewed in “real time” to provide diagnostic and therapeutic information that is not available with other techniques (Figure 6-12 ).
Arterial Pressure. Arterial pressure is a function of the volume of blood entering the arteries (both stroke volume and heart rate), the volume exiting the arteries (determined by peripheral resistance), and the compliance of the arterial vessels. From: Elsevier’s Integrated Physiology, 2007.
