What Would A V Q Scan Tell The Doctor About Pulmonary Blood Flow To The Affected Part Of The Lung
2. What would a v/q scan tell the doctor about pulmonary blood flow to the affected part of the lung?
VQ scans: With a VQ scan, the v refers to "ventilation, and the q refers to blood flow. The test is designed as a test for a blood clot in the lung. When this happens you have a blockage to blood flow (abnormal or reduced q) but normal air flow (ventilation). Other diseases in the lungs tend to reduce both v and q similarly. ...Read more
Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more
COPD: A V (ventilation) / Q (perfusion) lung scan is designed to tell a doctor why a patient MAY have shortness of Breath or chest pain. Most of the time these tests are ordered to confirm or exclude whether the patient has a pulmonary embolism (blood clot) in the lungs. However even negative V/Q scans can detect early to sever signs of emphysema /COPD. Which can also because of shortness of breath ...Read more
A LOT OF INFORMATIO: A v/q scan provides a lot of information to the doctor about the blood flow to the lung and airflow to the lung. It is done to diagnose blood clot in the lung (pulmonary embolism-pe). If the affected part of the lung has impaired blood flow but normal airflow (called v/q mismatch), a diagnosis of pe is entertained. If there is abnormal blood flow and abnormal airflow, then consider emphysema. ...Read more
When the doctor went in to take out fluids from the lung the fluid also had blood can it be lung cancer? They also said that there were spots on lungs
Yes: Blood flow to heart & lungs increase during exercise in order to improve oxygenation of muscles. Blood flow also increases to remove metabolic waste which you can feel as "burn" sensation after strenuous exercise. ...Read more
Midodrine: Midodrine is an Alpha agonist but has relatively little data compared to most other approved drugs. It shouldn't reduce pulmonary blood flow but I can't find data to prove that. ...Read more
Can be deadly: The size of the clot dictates how dangerous it is. Very very tiny emboli may not have much clinical consequence, unless it happens frequently. A large embolus that blocks large amounts of flow to the lung can cause symptoms including shortness of breath and even cardiac arrest. Unexpected shortness of breath should always be considered an emergency and evaluated by a doctor right away! ...Read more
Hi doctor, What kind of food help the lungs to eliminate tar and all chemical garbage in the lung for an ex smoker? And do you have others tips?
Smoke free: Remaining smoke free is the way to help your lungs clear themselves from smoking related debris. I am unaware of any food that will speed this process. ...Read more
Various: The usual warning signs of a pulmonary embolism (pe) include tachycardia (fast heart rate), dyspnea (shortness of breath), chest pain which can be pleuritic (ie hurts when you take a deep breath), fainting (known as syncope) and cyanosis (blue discoloration of the lips or nailbeds). ...Read more
Acute PE: Treatment of a pulmonary embolus essentially depends on the clinical symptoms at the time of diagnosis. The symptoms can be many and varied. Treatment options:. Blood thinners, thrombolytic s, ivc filter or embolectomy (surgical removal of blood clots). First priority is to stabilize patient if needed. The decision tree will be based on what is deemed most effective for the patient ...Read more
Would a Contrast-enhanced CT pulmonary angiogram also show lesions, abnormalities, masses, nodes, etc. Of the lung or does it only show the blood vessels? (Basically, does it provide more or less information than regular Chest CT?)
It provides: More information than a non contrast chest CT. All of the things you mentioned can be evaluated. ...Read more
Visited er, normal EKG and blood tests, 99%bloodoxy, doc says, oh and you have a little fluid on lungs, no big deal maybe up diuretic. Need to worry?
Not sure.: A little fluid on the lungs is not benign especially since I see no mention of heart failure or of diuretic. Seems as though you have had procedures to evaluate function of your heart. So...I am wondering on what evidence they deduced there was fluid in the lungs. Sometimes this may be suggested by labs or x ray but neither of these is completely reliable. Ask them directly. ...Read more

My grandmother has a blood clot and won't go to the doctor, should we be concerned? Hello, my grandmother had a blood clot that traveled to her lungs in 2002. Yesterday she discovered that she is having the same symptoms and therefore thinks that she has
I agree with the previous author: a blood clot in the leg, especially in someone who has already had a pulmonary embolism, is something that needs urgent treatment. High doses of Aspirin will not give the same protection as true blood thinners, and could very well cause an ulcer.
I understand that your grandmother does not want to take coumadin (warfarin). There is a new drug now available that offers similar protection without the need for regular blood tests. It's called pradaxa, and she should ask her doctor about it.
Another option would be to place a device in the vein that drains the legs that would capture any clots that are on their way to the lungs. That device is called a vena cava filter and, while not a cure for clots, can significantly reduce the risk of the worst complication (death by pulmonary embolism). ...Read more
Initially, E.R. MD: Once the diagnosis is made hospitalization for "blood thinners" will normally ensue, the E.R. Md will then turn the patient over to a hospitalist (internal medicine md) for in-patient management. After hospital discharge an internist or hematologist will provide follow up care. ...Read more

Had an endoscopy today vomitted blood 2days ago it was clear and doctor said it could be from the lungs and need to go to a pulmonary doctor?
Two possibilities...: There may be two possibilities in your case. Either: 1) the GI doctor missed something small like a dieulafoy's lesion or a healing mallory-weiss tear; or 2) the blood you vomited was ingested from another source like the nose, sinuses, teeth, or lungs. You need a tie-breaker opinion so I suggest talking with your primary care doctor about symptoms & risks, & allow him to direct your next step. ...Read more
My friends uncle had throat cancer (tumor) spread to lungs and blood according to doctors and say survival is impossible, what options does he have?
End of Life: Cancer that has spread to multiple organs with distant metastasis is regrettably, an extremely poor prognosis. The best option is to ask your doctor to enlist the services of hospice. The inter disciplinary team will not only attend to his physical needs for comfort through a doctor and nurse, but also address his nutrition and spiritual needs as well. My prayers are with you for peace. ...Read more

Not cancer: I'm really glad you quit smoking. Ask your personal physician about a referral to an otolaryngologist and a dentist who's gum-savvy. I'm going to trust your routine labs, including platelets, are within normal limits. Cancer almost never results from just 8 years of smoking at your age. ...Read more
