What is the pulmonary artery pressure?
Left and right pulmonary arteries are blood vessels through which the heart gives blood to the lungs. Blood pressure refers to the force with which the blood pushes on the walls of the blood vessels, and the pressure of the pulmonary artery or the pressure of the PA is a term that describes the blood pressure inside the pulmonary arteries. Normally, the blood passes without much effort to the lower chamber of the heart into the pulmonary arteries and the lungs and the pressure inside each pulmonary artery is low. In a state known as pulmonary hypertension, the pressure of the pulmonary artery is unusually high, leading to symptoms such as breathless, fatigue and a rapid heart rhythm. Some disorders, such as COPD, or chronic obstructive lung disease, are associated with low blood oxygen and reduced oxygen causes strengthening and narrow -grinding walls of the pulmonary artery. In a state known as pulmonary embolism, blood clots in arteries may develop, causing a sudden increase in pressure. It is also known that lung artery hypertension is associated with sickle -shaped diseases, a disorder in which red blood cells are unusual.
If the left side of the heart fails, perhaps due to a heart attack or defective heart valve, the pulmonary veins accumulate in the pulmonary veins, which leads to an increase in pulmonary artery pressure. Hypertension of pulmonary artery forces the heart to work harder to move blood to the lungs, and the right lower chamber of the heart can weaken and enlarge. This type of heart failure is known as Cor Pulmonale.
The pulmonary artery pressure can be examined directly by inserting the tube into the vein in the leg or arm and move it until it reaches the right side of the heart. From there it can be used to measure the pressures in both the pulmonary artery and in the right lower chamber of the heart. Chest X -rays can be accepted for lung and ECG or echocardiograms can be used to check the cardiovascular system to determine the possible cause of increased pulmonary artery pressure.
treatment of increased pulmonary artery pressure depends on the cause, but the condition itself has no drug. PerformingSymptoms are carried out to control any basic disease. In the case of some conditions or where no cause has been found, medicines that dilate blood vessels can be effective in reducing the pressure of the pulmonary artery.
