Randomized Controlled Trial
Arterial Monitoring System Leveling Method, Transducer Location, and Accuracy of Blood Pressure Measurements.
Many critically ill patients have invasive arterial catheters inserted for blood pressure monitoring. Whether catheter leveling method and alternative transducer location affect the accuracy of blood pressure measurements is unknown. ⋯ The findings indicate that any of the transducer locations evaluated may be useful in clinical prac-tice. Also, visual alignment rather than laser device leveling may be acceptable, except for DBP in the control location. More research is needed to strengthen these findings.
