Detailed explanation-1: -Vascular engorgement with erosion is another mechanism of hemoptysis. This occurs within the bronchial capillaries in the mucosa of the tracheobronchial tree as a result of acute infection such as viral or bacterial bronchitis, chronic infection such as bronchiectasis, or a toxic exposure such as cigarette smoke.
Detailed explanation-2: -The lungs have a dual blood supply from the pulmonary arteries and the bronchial arteries. The latter arise as a rule from the aorta and are the source of 90% of the cases of hemoptysis.
Detailed explanation-3: -Inflammation of the tracheobronchial tree renders airways congested, friable, and therefore susceptible to bleeding. Chronic respiratory tract infections lead to an increase in systemic arterial flow via formation of new vessels, which in turn are prone to rupture and cause haemoptysis [27].
Detailed explanation-4: -The increased pressure or lack of oxygen can damage your lung tissue, causing bleeding. This can appear as blood in your sputum. A PE that can cause such high blood pressure in the lungs would need to be very large and high risk (massive).
