Symptoms of pulmonary embolism can include:

Pulmonary embolism is a serious condition that occurs when a blood clot blocks a blood vessel in the lungs. Symptoms can vary widely, but they often include chest pain, shortness of breath, and in some cases, feelings of tightness in the chest or nausea. These symptoms occur due to reduced blood flow and oxygenation of the lungs and heart.

Choosing shock as a symptom highlights the severity of pulmonary embolism. Shock can manifest in cases of a significant blockage, leading to reduced cardiac output and blood pressure. This condition requires immediate medical attention and can be critical if not treated promptly. Symptoms such as feeling faint, confused, or weak can indicate that the body is not receiving enough oxygen, which supports the identification of shock as a related symptom.

While chest tightness and nausea can occur with pulmonary embolism, they are less definitive indicators compared to shock. The presence of shock indicates a more severe physiological response and is a critical symptom that necessitates urgent intervention, emphasizing the dangerous nature of the condition.
