Respiratory Danger

Typically, low oxygenated blood is brought from the right ventricle of the heart through the pulmonary arteries. Afterwards the hearts right side will pump the low oxygenated blood into both sides of the lungs. This is how the body receives much-needed oxygen. Following voyage through the right side of the heart and then to the left side, the blood is able to travel through the aorta to the rest of the body. However, with someone suffering from PPH, the body works inappropriately. The lungs very small blood vessels transform and then seal. When this occurs, the closed blood vessels prevent the flow of blood, thus causing the pressure in the pulmonary artery to increase about three times.http://www.johnsonlawgroup.com/wordpress/?cat=7
