Аннотация
The heart and lungs are intricately related. For congestive heart failure patients, fluid (plasma) backs up into the pulmonary system. As a result, pulmonary capillary pressure increases, causing fluid to seep into the lungs (pulmonary edema) within minutes. This excess fluid induces extra stress during breathing that affects respiratory health. In this paper, we focus on the effect that high pulmonary capillary pressure has on the development of this extravascular lung water (EVLW). A mathematical model of pulmonary fluid and mass transport mechanisms is developed in order to quantitatively analyze the transport phenomena in the pulmonary system. The model is then validated on 15 male heart failure patients from published literature [1]. The model shows reasonable estimation of EVLW in heart failure patients, which is useful in assessing the severity of pulmonary edema.
