MOVIE 3.  Function

Heart sounds cases

The chest piece is moved to the “anterior and/or posterior illustration auscultation area” on the screen to listen. At the chest piece area, sounds are heard.

Below the chest illustration is a phonocardiogram.

Heart sounds ON, Lung sounds OFF

When lung sounds are turned off, only heart sounds are played.

Press the “A, P, T, M” buttons under the chest illustration to move the chest piece to each area (strongest point) and listen the sounds of that area. Other than the “strongest point”, the heart sound/murmur is decreased. HR can also be adjusted.

Heart sounds ON, Lung sounds ON

If you turn on “lung sounds”, you can listen to both heart and lung sounds at the same time. Press the “A, P, T, M” buttons at the bottom of the screen to move the chest piece to each area (strongest point) and play the sounds of that area. Other than the “strongest point”, the heart sound/murmur is decreased.

Heart sounds ON, Pulse palpation ON

If you turn on the pulse function, you can listen to the heart sound while taking the pulse. In this case, you need two Kikuzo speakers as well as a stereo branch cable.

For Kikuzo to the pulse side (L Side), turn up the volume and gently palpate the silicon surface. The pulse is adjusted to the timing of the radial artery.

Lung sound cases anterior/posterior

For lung sound cases, the anterior and posterior are auscultated. When you move the chest piece, you can listen the lung sounds on that area. Press the 🔄 on the upper right of the screen to switch to the anterior/ posterior illustration.

Markers indicate the auscultatory and abnormal areas under the chest illustration.

Lung sounds ON, Heart sounds OFF

Move the chest piece displayed on the screen to listen to lung sounds. The heart sound can be switched ON/OFF, and it cannot be listened when it is OFF.

Lung sounds ON, Heart sounds ON

When you turn on the heart sound function, you can hear heart sounds along with  lung sounds.

Full-screen display and offline use

The chest illustration can be enlarged to full-screen. The screen is magnified with the heart, lung and pulse palpation settings and HR maintained just before magnification. In this full-screen mode, you can use it without an Internet connection. Also, the magnified screen does not display any information such as heart and lung icons or descriptive text.
