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.
You can use a CVP catheter to infuse I.V. fluids, administer I.V. medications, and draw blood specimens in addition to monitoring pressure. To measure the CVP, place the transducer of the pressure mon-itoring system (or the zero mark on a water manometer) at a stan-dard reference point, called the phlebostatic axis.After locating this position, mark the lo-cation on the patientâs body.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.
