Obtaining good. fusion splices is much easier today, due to continued improvements to the fusion splice equipment, procedures and. practices, in addition to the evolutionary improvements in controlling optical fiber geometries. As a result, losses.
In CT, the total amount of radiation incident on the patient, known as the DLP, is the product of the CTDIvol and scan length (in centimeters) and is measured in milligray-centimeters.
The CVP can be continu-ously measured by connecting either a catheter positioned in the vena cava or the proximal port of a pulmonary artery catheter to a pressure monitoring system. The pulmonary ar-tery catheter is used for critically ill patients.CVP monitoring isnât clinically useful in a patient with HF in whom left ventricular failure precedes right ventricular failure, because in these patients an elevated CVP is a very late sign of HF.) Before CVP catheter insertion, clip (donât shave) the site and cleanse it with an antiseptic solution.
