pulmonary pressure

In severe and prolonged cases, increased in pulmonary pressures are transmitted to the right side of the heart.

Since aortic pressure is higher than pulmonary pressure, a continuous murmur occurs.

When the lungs become functional at birth, the pulmonary pressure decreases and the left atrial pressure exceeds that of the right.

The pressure in the ventricles must be greater than the systemic and pulmonary pressure to open the aortic and pulmonic valves, respectively.

Aortic and/or mitral valve disease resulting in severe pulmonary hypertension (pulmonary pressure greater than 75% of systemic pressures) 6.

As soon as pulmonary pressure exceeds aortic pressure, shunt reversal (right-to-left shunt) occurs.

In patients with pulmonary hypertension, inhaled epoprostenol reduces pulmonary pressure, and improves right ventricular stroke work in patients undergoing cardiac surgery.

When the lungs expand at birth, the pulmonary pressure drops and blood is drawn from the right atrium into the right ventricle and through the pulmonary circuit.

The degree of polycythemia was also greater in these animals than in previous reports, and might have contributed to the increase in pulmonary pressure due to increased viscosity [ 19].

The Jatene procedure is ideally performed during the second week of life, before the left ventricle adjusts to the lower pulmonary pressure and is therefore unable to support the systemic circulation.

When directly or indirectly caused by increased left ventricular pressure pulmonary edema may form when mean pulmonary pressure rises from the normal of 15 mmHg to above 25 mmHg.

On the contrary, the systolic systemic pressure, the diastolic systemic pressure, the mean systemic pressure and the mean pulmonary pressure increased significantly only in group A at the same time point.

Splitting of S2, also known as physiological split, normally occurs during inspiration because the decrease in intrathoracic pressure increases the time needed for pulmonary pressure to exceed that of the right ventricular pressure.

Normal human speech is produced with pulmonary pressure provided by the lungs which creates phonation in the glottis in the larynx that is then modified by the vocal tract into different vowels and consonants.

The potential problems facing Mr. Angel, according to his team, include breathing underwater, which increases pulmonary pressure; falling asleep, which risks complications with the mask; and the inevitable pruning, which makes the skin susceptible to cuts.

Eventually, due to increased resistance and decreased compliance of the pulmonary vessels, elevated pulmonary pressures cause the myocardium representing the right heart to hypertrophy, commonly understood as right ventricular hypertrophy or RVH.
