What are common signs of a pulmonary embolism after surgery?

Sudden shortness of breath and chest pain are classic signs of a pulmonary embolism, particularly following surgery. A pulmonary embolism occurs when a blood clot travels to the lungs, blocking a blood vessel and causing a significant reduction in blood flow. This can lead to impaired gas exchange in the lungs, resulting in acute symptoms.

Patients often experience a rapid onset of shortness of breath, which may be accompanied by sharp chest pain that can worsen with deep breathing or coughing. Additionally, the stress of surgery can increase the risk of blood clots forming in the legs, which can then dislodge and travel to the lungs, making awareness of these symptoms critical in early detection and treatment.

The other options, such as fever and wound redness, are more indicative of infection or complications related to the surgical site. Sneezing and nasal congestion are typically associated with upper respiratory issues, not pulmonary embolism. Headache and nausea could stem from various causes post-surgery but do not specifically suggest the presence of a pulmonary embolism.
