Activity Summary

Required reading for all learners: Implicit Bias impacts patient outcomes

Many critically ill patients have invasive arterial catheters inserted for blood pressure monitoring. Whether catheter leveling method and transducer location affect the accuracy of blood pressure measurements is unknown. The findings indicate that any of the transducer locations evaluated may be used in clinical practice. Also, visual alignment rather than laser device leveling is acceptable, except for diastolic blood pressure in the control location.


  • Identify two experimental locations for arterial monitoring system transducers used in this study.
  • Determine one limitation of the study.
  • Describe one positive and one negative effect for each transducer location.
