Air Embolism (Definition)

Blood vessels are made to carry blood - liquid. A small amount of air in a vessel is not usually a big deal as it will be absorbed into the blood. Larger volumes of air (10 mL or larger) can be significant to block blood flow in that vessel. That is bad in the brain (stroke) and really bad in the heart because ...Read more

What does blood clot in the lungs (pulmonary embolus) show on ventilation perfusion scan?

What does blood clot in the lungs (pulmonary embolus) show on ventilation perfusion scan?

Lack of blood flow: A ventilation perfusion scan is a test for a blood clot in the lungs, or pulmonary embolism. If there is a blood clot, an area of the lung will not be perfused, but will be ventilated, and therefore a mismatch will be seen. ...Read more

Vq scan and pulmonary embolism?  How accurate is the scan?

Not realy very: Ventilation/perfusion scan (v/q scan or lung scintigraphy), which shows that some areas of the lung are being ventilated but not perfused with blood (due to obstruction by a clot). This type of examination is used less often because of the more widespread availability of ct technology, however, it may be useful in people who have an allergy to iodinated contrast or in pregnancy. Thanks. ...Read more

What are the differences between pulmonary perfusion scan and pulmonary ventilation scan?

Lung V-Q scan: Ventilation scanning involves the patient breathing in a radiotracer while perfusion scanning involves injecting the radiotracer through an iv. The procedure is done usually to evaluate the presence of absence of a pulmonary embolism (usually a blood clot) and involves comparing the radiotracer's presence in the alveoli vs. Its presence in the lung circulation. ...Read more

How can one differentiate pulmonary embolism from extra pleural effusion tuberculosis?

How can one differentiate pulmonary embolism from extra pleural effusion tuberculosis?

CT angio: of the chest is usually diagnostic for pulmonary embolism. Analysis of the pleural fluid, including mycobacterium cultures would point toward tuberculosis, which otherwise may be difficult to diagnose, unless living in an endemic area. Beware that the 2 conditions may coexist, unfortunately, and having 1 does not rule out the other. ...Read more

My chest x-ray shows hyperinflated lungs. Can anxiety cause air trapping from poor breathing?

NO: Air trappin is generally due to air OBSTRUCTION in the smaller lung (bronchial) tubes. S guess a VERY DEEP Breath ...held while the xray is taken could give an appearance of hyperinflation but Radiologist know the difference!!!

37 wks preg. CT scan of lungs ruled out oulmonary embolism but showed minor dependency change and atelectasis. suggested air trapping. is this concern?

What they: are calling dependent changes are usually normal and simply related to the effect of gravity on your lungs when you lay on your back. "Air trapping" relates to retention of excess air in the lungs or parts of the lungs. The CT findings of air trapping can be seen in normal individuals, but also in asthma, chronic bronchitis, and other entities, so talk to your doc about the results. ...Read more
