Central venous pressure (CVP) and pulmonary capillary wedge pressure (PCWP) measurements are common nursing procedures in intensive care units. One of the most important technical considerations for accurate measurements of CVP and PCWP are appropriate leveling and zeroing of pressure transducers. Adequate measurements of CVP data are prerequisite for correct interpretation and appropriate management. This innovation is used of lasers level to replace conventional level to improve identify external reference and eliminate parallax error. These data indicate that the use of laser level with accuracy and practicality decreases the leveling time in measurement (26.0±5.75 vs 62.0±27.16 seconds, p=.001). Hence, laser level is considered worthy of clinical use.
