In all groups, the average pressure in the pulmonary arteries is higher than 25 mmHg at rest or 30 mmHg during physical activity. The pressure in normal pulmonary arteries is 8â20 mmHg at rest.
Mean arterial pressure can be approximated by adding one-third of the pulse pressure to the diastolic pressure. For a person with a blood pressure of 120/80, for example, the mean arterial pressure would be approximately 80 + 1/3 (40) = 93 mmHg. Mean arterial pressure = diastolic pressure + 1/3 pulse pressure A rise in total peripheral resistance and cardiac rate increases the diastolic pressure more than it increases the systolic pressure.
