This 49-year-old gentleman has been suffering from shortness of breath on exertion for the past 3 days. This has caused him to rest after walking 10-15 meters, despite previously having no issues with exercise. He has not experienced any chest pain or cough. Two weeks ago, he took a flight back to Miami from Italy. The man is overweight, weighing 130kg and measuring 180cm in height. He was admitted to the hospital with a probable diagnosis of PE. Upon admission, he appeared uptight and was experiencing tachypnea and sweating. His JVP was not visible. There was no evidence of calf tenderness or swelling. He exhibited signs of peripheral cyanosis.
