Is it possible to have pulmonary edema without adventitious breath sounds?

Pulmonary edema can indeed occur without the presence of adventitious breath sounds. This condition arises when excess fluid accumulates in the lungs, often due to heart failure or other conditions affecting the heart’s ability to pump efficiently. While it is common for adventitious sounds, such as crackles or wheezes, to be present due to fluid in the alveoli, it is not a definitive indicator of pulmonary edema's existence.

For instance, in the early stages of pulmonary edema, patients may not exhibit any audible breath sounds beyond normal lung sounds despite having fluid in the lungs. Additionally, if fluid levels are significant but do not severely compromise lung function, a person could present with minimal or no abnormal lung sounds. The absence of these sounds may also occur if a patient has underlying conditions that mask the typical findings associated with pulmonary edema.

Overall, while adventitious breath sounds are a common clinical finding in pulmonary edema, the relationship is not absolute, making it entirely possible to have pulmonary edema without these abnormal lung sounds.
