From a faint click to an uncommon S3, the E-Scope provides users with clear, amplified heart or breath sounds.  

The E-Scope Electronic Stethoscope II utilizes state-of-the-art electronic technology to amplify heart, breath and Korotkoff sounds so they become much easier to hear. The sound is pure and clean. Compared to acoustic stethoscopes, murmurs and faint blows are much more distinguishable (see the below chart ).

The E- Scope is approximately 30 times louder than an acoustic stethosdcope.

The E-Scope is easy to use. All controls are on the chest piece of the stethoscope. The controls include:
Volume Up Volume Down Heart or Breath Sounds switch

Afraid you might leave the E-Scope ON and lose battery life? The E-Scope has a built in timer that automatically shuts the unit off after 1.5 to 2 minutes. To reactivate the E-Scope, simply press any control button on the chest piece and you're back in business. The E-Scope remembers the last volume setting upon restart.    Battery life is estimated at approximately 4 months using an off- the-shelf AAA battery!

Additional features include:
External output for recording or telemedicine

3 types of eartips Softpack carrying case Operator's manual

EMS - paramedic? The E-Scope EMS provides exceptional sound quality in a very high noise area.
E-Scope EMS Electronic Stethoscope includes the 'Specialist 'Chest Pieces - Pediatric, Adult Bell and Adult Diaphragm

The "Specialist" heads are machined from high- grade stainless steel with a Delrin non-chill ring. They provide a 50% increase in sound sensitivity, a reduction in outside noise and a comfortable feel.

Behind-the-Ear (BTE) Hearing Aids present a more difficult problem as the hearing deficit of the professional user is generally more severe. When people lose their hearing, it is usually in the frequencies in which voice sounds are heard (500-4000Hz). Heart sounds, on the other hand, are much lower. The first and second heart sound are between 70-120Hz. Murmurs are generally found between 150-400Hz and breath sounds fall between 70-2000Hz with occasional frequencies up to 4000Hz.

Hearing aids reproduce voice very well. Heart sounds and Korotkoff sounds are another story. Hearing aids just don’t reproduce these sounds well due, in part, to the very small speaker. Cardionics has tested several current model hearing aids with the E-Scope by inserting a known sound into the E-Scope and measuring the output. We then attached a hearing aid, inserted the same sound and measured the output from the hearing aid. The results have been published in Technical Information Bulletin No. 101 by Cardionics. Copies are available upon request. The sound output from the hearing aid lacks the sound quality needed to properly diagnose a heart sound. Increasing the volume merely distorts the sound further.

As a result, we are reluctant to recommend a silhouette or direct audio input cable (DAI) for use with a BTE hearing aid. They should be used only as a last resort and by order of an audiologist.Many of the newer hearing aids have an “open fit” style. That is, the tube that is inserted into the ear does not completely occlude the ear canal. In this situation, the user generally has some low frequency hearing capability. For this type of hearing aid, we recommend the E-Scope Hearing Impaired Model, cat. No. 718-7710 with the 718-0405 traditional style headphone.

Cochlear Implants (CI). There are three manufacturers of Cochlear Implants with whom we have worked – Cochlear America, MedEl and Advanced Bionics. Advanced Bionics has a frequency limitation. It will not reproduce frequencies below 250Hz so it is not recommended for use in cardiac auscultation or taking blood pressure.

By attaching a thin cable to the speech processor and mapping the CI properly, heart, breath, bowel and Korotkoff sounds generally can be heard quite well. One of the employees at Cochlear America given us a written guide to mapping the Freedom Nucleus CI with the E-Scope. 

BAHA (Bone Anchored Hearing Aid). The E-Scope has been successfully used with BAHA implants by connecting it to the Audio Adapter Cable supplied as part of the BAHA. The user must increase the low tones of their processor for best use.

Cardionics has had a good deal of experience in this area. Please don’t hesitate in calling us if we can be of help.

Cardionics’ E-Scope II Electronic Stethoscope paired with Cochlear Implant Speech Processor

The Cochlear Implant Speech processor will need to be adjusted for the low frequency sounds of heart and lungs. Your Audiologist must reduce the frequency boundary to 100Hz or lower if possible.

Heart/Lung sounds are very different than speech. They would be screened out of a typical speech program. Some of the heart/lung sounds would be eliminated or diminished considerably if you attempt to listen on speech program set around 250Hz.

Once the processor’s frequency boundary has been lowered you will decide how to get the sound into the processor. Outlined below are the different configurations available.

You may use large headphones (718-0408). The headphone ear pad would cover the entire ear with processor left in place. You would simply place over the top and listen.

Patch cord (711-7129) with the personal audio cable connected to the processor. This will give you the best sound. The first cable being the Personal Audio Cable supplied with your processor. This cable has a special connector that will plug into the bottom of the ear worn processor. The end of the Personal Audio cable will attach to an E-Scope Patch cord. This patch cord will allow you to connect to the side output of the E-Scope. This square 4pin connector on the side output of the E-Scope is most appropriate to drive a speech processor.

Silhouette Induction Coil or Hatis (711-7133) is a small flat plastic device that is worn beside your speech processor. This device will magnetically transfer the sounds into the T coil program. This will eliminate the need to plug/unplug your ear worn processor each time you need to listen. This method is the most convenient. T coil program must be lowered to at least 100Hz.
