Answer:
Pulmonary embolism
Step-by-step explanation:
Pulmonary embolism (PE) is the occlusion or plugging of a part of the pulmonary arterial territory (blood vessels that carry oxygen-poor blood from the heart to the lungs to oxygenate it) due to an embolus or thrombus that comes from another part of the body (a detached thrombus (embolus) from somewhere in the venous territory) the most common clinical manifestations or symptoms are dyspnea (feeling short of breath). The obstruction of a vessel immediately causes an alteration in ventilation / perfusion due to an increase in dead space. The two immediate consequences are hypoxemia due to a decrease in the effective surface suitable for gas exchange and pressure overload of the right ventricle.
