Blood pressure in the aorta
WebAortic dissection most often happens because of a tear or damage to the inner wall of the aorta. This very often occurs in the chest (thoracic) part of the artery, but it may also occur in the abdominal aorta. When a tear occurs, it creates 2 channels: One in which blood continues to travel. Another where blood stays still. WebOct 31, 2016 · Pulmonary blood pressure is normally a lot lower than systemic blood pressure. Normal pulmonary artery pressure is 8-20 mm Hg at rest. If the pressure in the pulmonary artery is greater than 25 mm Hg at rest or 30 mmHg during physical activity, it is abnormally high and is called pulmonary hypertension.
