What risks exist for the patient in undergoing an impedance phlebography?
Impedance phlebography is painless and safe. It presents no risk to the patient.
What is impedance phlebography?
Impedance phlebography is a noninvasive test that uses electrical monitoring to measure blood flow in veins of the leg.
What is the purpose of impedance phlebography?
Impedance phlebography may be done in order to: detect blood clots lodged in the deep veins of the leg, screen patients who are likely to have blood clots in the leg, detect the source of blood clots in the lungs.
What care should a patient receive after an impedance phlebography?
The patient may resume normal or postoperative activities after the test.
What characteristics does a normal impedance phlebography have?
Normally, inflating the pressure cuff will cause a sharp rise in the pressure in the veins of the calf because blood flow is blocked. When the cuff is released, the pressure decreases rapidly as the blood flows away.
Is characteristics impedance of a filter is same as output or load impedance?
load impedance
What are some other names for phlebography?
also called venography, ascending contrast phlebography, or contrast phlebography
What are the dc characteristics of an OP-AMP IC 741?
High gain high input impedance low output impedance
What precautions need to be taken when using impedance phlebography?
Because this test is not invasive, it can be done on all patients. However, the accuracy of the results will be affected if the patient does not breathe normally or keep the leg muscles relaxed. Compression of the veins because of.
What is a normal result for a phlebography test?
Normal phlebography results show proper blood flow through the leg veins.
What is another name for venography?
Venography (also called phlebography, ascending contrast phlebography, or contrast venography) is an invasive diagnostic test
How should patients be prepared for an impedance phlebography?
Patients undergoing this test do not need to alter their diet, change their normal activities, or stop taking any medications. They will wear a surgical gown during the test, and be asked to urinate before the test starts.
