Can a blood clot affect respiration?

Yes, a blood clot can affect respiration if it occurs in the lungs, leading to a condition known as pulmonary embolism. This happens when a clot travels to the pulmonary arteries, blocking blood flow and reducing oxygen exchange. Symptoms may include shortness of breath, chest pain, and coughing, which can severely impair respiratory function. Prompt medical attention is crucial in such cases to prevent serious complications.
