美风解释得对, 肺充血有时是由心衰造成的, 还有肺部感染或高血压也会导致. 好喜欢美风的歌声!

Lung congestion - distention of blood vessels in the lungs and filling of the alveoli with blood as a result of an infection, high blood pressure, or cardiac insufficiencies (i.e., inability of the heart to function adequately). The alveoli in the lungs are minute air sacs where carbon dioxide and oxygen exchange occurs.
