The technique of occlusive-cuff impedance plethysmography.  How to use this sensitive, noninvasive tool to detect proximal DVT.
Occlusive-cuff impedance plethysmography (IPG) is a rapid, reliable, and noninvasive method of diagnosing proximal deep venous thrombosis (DVT) in the lower extremities.  The test is relatively easy to perform and carries an overall accuracy of greater than 90% when compared with venography.  IPG is useful in detecting acute, symptomatic DVT and in determining the presence of recurrent DVT.  In certain patients with nondiagnostic lung scans in whom pulmonary embolism is suspected, IPG may be helpful in determining appropriate therapy without use of pulmonary angiography.
