What does VQ mean in PHYSIOLOGY
Ventilation/perfusion, or V/Q, is a type of medical scan used to detect pulmonary embolism, a blockage in the lungs caused by blood clots. This diagnostic procedure involves two separate imaging techniques that measure the flow of air and blood into and out of the lungs. In order for a diagnosis of pulmonary embolism to be made, both scans must indicate an obstruction. The scans are often done together on the same day, but can also be done separately over a period of time.
VQ meaning in Physiology in Medical

Procedure
A V/Q scan is typically ordered after other blood tests and scanning techniques fail to provide clear evidence of pulmonary embolism. During the procedure, a subject lies on their back with their arms at their sides in the prone position. A radiology technician will then inject radioactive isotopes into an intravenous line during two distinct scans: the ventilation scan and the perfusion scan. The ventilation scan assesses the amount of oxygen entering and leaving each lung area while breathing normally through an open mouthpiece connected to a tube filled with low-density gas (air). The perfusion scan measures how much blood is traveling from either side of your heart through your lungs by filling the same tube with high-density liquid (water).
Results
V/Q scans are interpreted by trained technicians who compare air flow and blood flow data from both sides of your chest. The results may indicate normal findings or suggest signs consistent with pulmonary embolism such as areas where there is no air movement but significant blood flow or vice versa. Results should always be discussed with your doctor before making any decisions about treatment plans.
Essential Questions and Answers on Ventilation/perfusion, ie V/Q scan in "MEDICAL»PHYSIOLOGY"
What is a V/Q scan?
A V/Q scan, or ventilation/perfusion scan, is a diagnostic imaging test used to evaluate how well blood is flowing into the lungs. It can also be used to identify any abnormalities that may affect your breathing or oxygen levels. The test involves breathing in a radioactive gas and then having an x-ray taken of your lungs. The results from the scan will be used to create an image that shows how much air you are getting, as well as how well blood is circulating through the lungs.
How is a V/Q scan performed?
The V/Q scan begins with the person lying down on a table and having an injection of radioisotope material injected into their arm intravenously. This material collects in the lungs and helps produce images for interpretation by the medical team. After receiving the injection they will then have an x-ray done of their chest which will provide additional data for interpretation by the medical professionals interpreting the results of the scan.
What are some risks associated with undergoing a V/Q scan?
There are minimal risks associated with this procedure; however, there could be risks associated with exposure to radiation during the x-ray portion of this scanning process. Additionally, there could be adverse reactions due to allergic reactions from certain materials used in some medications given before or after this procedure. These reactions should always be reported to your care provider right away if experienced.
Are there any precautions I should take before a V/Q Scan?
It is best to arrive early for your appointment and follow all instructions given prior to receiving any scans or tests such as avoiding eating within four hours beforehand and avoiding wearing metal objects during scans such as jewellry or clothing with metals sewn into them which may interfere with imaging results. Additionally, it may also be helpful to speak openly about any allergies you have so that your healthcare provider can take necessary precautions when necessary.
Do I need special preparation for my V/Q Scan?
Yes - Generally you should limit movement prior to a V/Q Scan due to its reliance on x-rays, however other preparations may also involve changing into comfortable clothes for a few hours before and after testing so that images captured are not distorted by clothing during testing itself.. It is also important to discuss any medications that you are currently taking, as well as any allergies you may have which can help determine necessary preparations throughout testing itself
How long does it take for me to recover after having undergone a V/Q Scan?
Most people usually feel normal soon after having undergone one of these scans apart from feeling slightly tired due to lying still during performing one's tests; however waiting times till gaining full mobility again vary depending upon individual response rates following administration of intravenous materials used during scanning procedures.
Does insurance cover costs related to undergoing a V/Q Scan?
Coverage may vary depending upon individual policies; however most insurance plans do cover at least partial costs related directly towards obtaining this type of imaging study.
Final Words:
Ventilation/Perfusion (V/Q) scans are invaluable tools in diagnosing conditions like pulmonary embolism in patients who have already shown abnormality on other forms of imaging tests. By providing detailed information about airflow and bloodflow within each lung area, this diagnostic tool can help doctors determine if blockages exist due to abnormalities caused by a pulmonary embolism.
