Pulmonary vascular disease: Pulmonary edema – The Diagnosis

Pulmonary vascular disease is defined as a condition of blood flow to the lung’s artery is blocked suddenly due to a blood clot somewhere in the body, including pulmonary embolism, chronic thromboembolic disease, pulmonary arterial hypertension, pulmonary veno-occlusive disease, pulmonary arteriovenous malformations, pulmonary edema, etc.
Pulmonary edema
Pulmonary edema is defined as a condition of fluid accumulation in the air spaces and parenchyma of the lungs of that can lead to difficult of breathing and respiratory failure.
B. Diagnosis
If you are experience certain symptoms above and suspected to develop, after a complete physical examination, including checking the presence of fluid in your lungs and recorded of your family, the tests which your doctor orders may include
1. Blood test
Blood chemistry tests are a procedure to examine the general health of a patient, but in this case it may be used to test for oxygen levels.
2. Lung ultrasound
Neurogenic pulmonary edema (NPE) is an acute life-threatening complication associated with many forms of central nervous system injury. NPE usually appears within minutes to hours after injury and has a high mortality rate if not recognized and treated appropriately. Lung ultrasound quickly provides at the bedside relevant information on the state of aeration and ventilation of the lung(25).
3. Chest X-ray
The aim of the test is to check for the presence of fluid in the lung. According to the study by the researcher team lead by Liebman PR, the portable chest x-ray technic does not provide quantitative information regarding cardiopulmonary function. It is especially hazardous to accept an x-ray diagnosis of congestive failure as the cause of pulmonary edema(26).
4. Electrocardiogram (ECG)
The aim of the test is to look for heart rhythm problems or signs of a heart attack. There is a report of a case of presented markedly low surface electrocardiographic (ECG) voltage and an infarction pattern are rapidly reversed with renal hemodialysis for pulmonary edema(27).
5. Echocardiogram
The aim of the test is to check for problems of the heart muscle including weakness, thickness, failure to relax properly, leaky or narrow heart valves, or fluid surrounding the heart(28).
