SUMMARY

The discussion centers on the discrepancies in lead counts displayed by the Datex-Ohmeda S/5 anesthesia and vital sign monitors when using a disposable 10-lead EKG leadwire system. The leadwire system is designed for intensive care units and aims to reduce artifacts that trigger false alarms. Users report that a 5-lead adapter cable shows different lead counts on various monitors, indicating potential compatibility issues or differences in monitor configurations. The conversation highlights the need for improved alarm accuracy and artifact elimination in EKG systems.

PREREQUISITES
  • Understanding of EKG lead configurations and their applications in monitoring.
  • Familiarity with Datex-Ohmeda S/5 monitor series and their functionalities.
  • Knowledge of artifact sources in EKG readings and methods for their reduction.
  • Experience with disposable medical device design and implementation.
NEXT STEPS
  • Research methods for reducing EKG artifacts in clinical settings.
  • Explore compatibility specifications for Datex-Ohmeda S/5 monitors.
  • Investigate advancements in disposable EKG leadwire technology.
  • Learn about alarm management systems in critical care monitoring.
USEFUL FOR

This discussion is beneficial for biomedical engineers, medical device developers, and healthcare professionals involved in EKG monitoring and alarm systems in intensive care environments.

Do you know what are the main ways to increase EKG's alarm accuracy whilst eliminating artifacts?

Sure. What is the context of the question?

And welcome to the PF, BTW. :smile:

Sorry for not keeping it updated.
I've recently developed a disposable 10-lead EKG leadwire system specifically for Anesthesia and vital sign monitors for Intensive care units. Due to the massive use of equipment in this unit the leadwires are fully shielded. However, artifacts still exist which also causes false alarms from time to time. I wonder what is the main ways to increase alarm accuracy, eliminate artifacts so I can adopt in my products.

My product--a disposable EKG leadwire system, carries with an adapter cable. When I use a 5-lead adapter cable to Datex-Ohmeda S/5 anaesthesia monitor, it shows 5 leads. But when I use the same cable to Datex-Ohmeda S/5 vital sign monitor or S/5 compact, it shows 3 leads. What is going on?
