Doppler vs Electronic Stethoscope

I was looking through the differences between a doppler and electronic stethoscope. I was wondering if anyone would be able to add what you might think and how each can be beneficial for vascular assessment of the lower limb? Cos if both works the same, we might just carry a simple and compact electronic stets than a doppler (which requires those messy gels).

below is an example.

 

I've had similar feelings about this also. The only drawback I can think of concerns circumstances when patients have suspected calcified vessels.

 

They don't work the same - but close enough in practical day to day use.

The main difference is the ability to extend your assessment beyond qualitative (listening: ie stethescope), to qualitative (waveform interpretation: ie Doppler) which is far more meaningful and open to analysis.

That, and the fact that lower extremity arterial pulses are usually harder to pick up with a strethescope - particularly deeper vessels such as the tibial and popliteal segments, and smaller vessels such as the digital arteries.

yeah. I understand what you were saying. I hope you're referring to the electronic stethoscope.

Cos the electronic stethoscope produces sound waves.. not just lub dub. The same sound that a doppler produces.

the above link will gives you some idea on what sound the electronic stets produces.

Sorry if I sound ignorant here... ehehehe I'm just a second year anyways.

Cheers!
