Pulmonary embolism is a pathology with a high incidence in our environs . The hurtful , hemodynamic changes that prepare once the intercalation has been established , make up one’s mind the serious and sharp complications that this result couch .
Can a Pulmonary Embolism (PE) Cause Atelectasis?
In sexual intercourse with pneumonic backlash of pulmonary intercalation , the reduction or absence of pulmonary perfusion produces increased alveolar dead outer space , reflex bronchoconstriction , and atelectasis . The alveolar produce hypoventilation , the existence of zones of pulmonary infarct and alteration in the pulmonary surfactant bring about hypoxemia and retention of carbon dioxide .
Mechanism Of Heart Failure
When the obstruction of the pneumonic arteries due to intercalation occur , the following are affected : 1 ) Pulmonary tissue , 2 ) The pulmonary circulation , and 3 ) The function of the right and left the heart . The level of cardiorespiratory via media correlate with the severity of the occlusion produced by the embolus and with the stage of the affected role ’s implicit in disease .
Alterations In Gas Exchange
Abnormalities of gas exchange in the lungs are an inevitable consequence of pulmonary embolization . It is likely that the etiology of the gas exchange abnormality is complex and multifactorial , and may disagree from one patient to another . abnormality of gun exchange in these patient are complex and depend on the size and characteristics of the embolic textile , the extent of the occlusion , the patient role ’s previous cardiorespiratory status , and the time elapsed since embolization .
The right wing - to - left shunt , an revision in the ventilating system - perfusion relationship and in certain patient , a drop in the oxygen tension of the venous blood , has act a role in the process of abnormal gasoline exchange leading to hypoxemia ( an abnormal decrement in the oxygen partial press in the arterial blood ) follow the pulmonary embolism . The etiology of these physiological alterations has not been clearly defined , but there are several hypotheses :
The pulmonary vascular disease is in general defined as an anatomical narrowing of the pulmonary vascularization . In a broad common sense , it can also be delimitate as a variety in the pulmonic vascular impedance in certain regions , which comes from anomalies in the lumen or the walls of pulmonary vessel . There are different clinical situations that cause pulmonic vascular disease , where gas central can be evaluated using the multiple elimination technique .
