How to record auscultation sounds using Nexstetho
A dedicated application is under development.
Yes, the chestpiece can be removed from your stethoscope.
If you are not sure about the installation, we have special products that can be simply attached to your stethoscope.
We are constantly updating our list of recommended models, so please check back. https://www.nexstetho.com/support
Nexstetho itself does not have built-in speakers, so please bring headphones, earphones, or speakers separately.
We will update this page as needed for recommended equipment. https://www.nexstetho.com/support
Some connections can be made depending on the shape of the connection, but this has not been verified.
Please try using the O-rings and tubes that come with Nexstetho.
Please note that Littmann Master Cartiology is not compatible.
If you are not sure about the installation, there is a chest piece kit with a custom-made Focal chest piece.
Sound quality often depends on the performance of headphones or earphones and speakers. Products with excellent reproduction capabilities, especially in the low frequency range of 20hz to 60hz, are desirable. We have tested the connection and sound quality, and have compiled a list of products that we believe are compatible with Nexstetho, which we hope you will refer to.

Since the degree of disability varies from person to person, some people seem to benefit from it while others do not.
However, there have been reports of nurses with cochlear implants who have been able to hear again with Nexstetho. Please consult your specialist.
Depending on the situation, try the following
If you feel the heartbeat is weak, press the I button on the Nexstetho main unit. Pressing the Ⅰ button will enter a mode that makes it easier to hear the heartbeat.
Make sure that the chest piece is securely installed all the way to the back with no gaps or wobbling. Please use the supplied O-rings and tubes to adjust the fit.
If you cannot hear the heartbeat completely, the direction of the chestpiece opening may be reversed. Please remove the chestpiece from Nexstetho once, turn the middle shaft, and then put it back.
The tips to avoid feedback are as follows.
Place the speaker at a distance from the main body of Nexstetho.
Place the speaker facing backward.
Wrap the main body of the speaker in a towel, etc. Heartbeats and other sounds are low frequency and can be heard even when wrapped in a towel.
In this environment, we hope you will try to increase the volume of the speakers as needed.
