Why Does an EKG Leadwire System Show Different Lead Counts on Various Monitors?

  • Thread starter Thread starter justinfranco

AI Thread Summary
The discussion centers on the challenges of ensuring accurate EKG alarm systems while minimizing artifacts, particularly in a new disposable 10-lead EKG leadwire system designed for anesthesia and ICU monitors. The user notes that despite the leadwires being fully shielded, false alarms still occur, prompting a search for solutions to enhance alarm accuracy. Additionally, there is confusion regarding lead counts displayed on different Datex-Ohmeda monitors when using the same adapter cable, with variations noted between anesthesia and vital sign monitors. The conversation highlights the need for clarity on how different systems interpret lead connections and the importance of addressing artifact issues in critical care settings. Overall, improving EKG alarm accuracy and understanding lead count discrepancies are key concerns in this context.

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?

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
