How does congestive HEART failure affect the LUNGS?

The heart pumps blood around the body. When it becomes inefficient, like in mitral valve disease, while some blood is still pumped forward, some also flows backwards. This backwards flow, often causing turbulence which is heard as a murmur, means there is higher blood pressure before the dodgy valve than there should be.

There’s only so much blood volume a patient’s organs can handle. If this is a chronic problem then the liquid of the blood will spread into surrounding tissue. If it’s right sided heart failure then that fluid usually ends up causing a swollen liver and ascites. In left sided heart failure, like the picture, that fluid ends up accumulating in the lungs.

Because the lungs are like a sponge and coated with surfactant, the fluid and air mix and are often coughed up as foamy bubbles, with blood staining as it gets worse.

You can accidentally accomplish the same thing by giving a patient too much intravenous fluid therapy too quickly.

When the patient is not breathing quickly (i.e dead) then the fluid isn’t mixed with air, doesn’t foam and just pours out.

While heart patient can just drop dead, usually they’re drowning.
