In patients with pulmonary oedema, venous capacitance is increased, thereby decreasing left ventricular filling pressure.
在病人的肺水肿,静脉电容增加,从而减少左室充盈的压力。

Secondary lymphangiectasia may be caused by granulomas or cancer causing lymphatic obstruction, or increased central venouspressure (CVP) causing abnormal lymph drainage.
Dyspnea due to elevated pulmonary venouspressure and pulmonary edema is increased in the recumbent position and decreased by sitting or standing (orthopnea).
