Pulmonary embolism primarily presents with symptoms that stem from obstructed blood flow in the pulmonary arteries, leading to significant respiratory distress and cardiovascular complications. Shortness of breath is a hallmark symptom, as the obstruction reduces oxygenation and can provoke a sense of breathlessness. Tachycardia frequently occurs as the heart compensates for the reduced oxygen levels and increased effort to maintain blood flow. Hypotension can also develop due to decreased cardiac output or collapse of the circulatory system as a result of a large embolism.

In contrast, a headache is not a typical symptom of pulmonary embolism. While it can occur in certain situations or as a result of secondary issues related to stress or pain, it does not directly correlate with the physiological changes associated with a pulmonary embolism. Understanding the distinct clinical presentations of conditions is crucial for accurate assessment and management in emergency situations.
