title: Comparison of right atrial and pulmonary capillary wedge pressures.
abstract: The right atrial pressure (Pra) was compared to the pulmonary capillary wedge pressure (Pcw) in 54 patients. In patients with heart disease, the correlation of Pra with Pcw was poor. However, in patients without clinical heart disease, Pra approximated Pcw, in both absolute number and change. This finding was independent of disease process or the presence of controlled mechanical ventilation.
