Symptoms of Pulmonary Edema. Blood is filled with oxygen from your breath in your lungs. Oxygen is then carried throughout the body to every organ and tissue. In cases of pulmonary edema, the lungs fill with fluid. As the amount of fluid in the lungs increases, the body struggles to gain oxygen. The symptoms will grow progressively worse until the fluid is removed. Symptoms of pulmonary edema include: 1  breathlessness (feeling like you canât catch your breath).
