What is pulmonary Pressure?

Pulmonary arteries are the carriers of blood from the heart to the lungs. The pressure of the blood in these arteries is known as the pulmonary pressure. Variations of pressure in this artery could have varying effects on the body depending on the intensity of the variation. Any kind of tension in the pulmonary artery could be felt due to a number of diseases related to the lungs or the heart. In general the pressure in a pulmonary artery is around 15 mm Hg at rest.  Pulmonary hypertension is a consequence of heart and lung diseases as this is the only artery carrying deoxygenated blood from the heart to the lungs. In several cases, a pulmonary hypertension is due to pulmonary embolism and scleroderma. Pulmonary hypertension is increased pressure in pulmonary artery, pulmonary veins or the pulmonary capillaries which form the lung vasculature. Pulmonary hypertension could lead to breathing problems or shortness of breath, dizziness and also fainting. This kind of hypertension is characterized by decreased tolerance to exercise leading to heart failure. Pulmonary hypertension generally shows out itself in five different forms with different effects. A thorough diagnosis is necessary to understand the type of hypertension. It is also seen that this disorder also has a strong connection with medical conditions of the family members or the family history.
