The 63rd Annual Meeting of the Japanese Respiratory Society NBI Lung stethoscope corner（For internal only）
At the 63rd Annual Meeting of the Japanese Respiratory Society, we set up a lung auscultation experience corner at the Nippon Boehringer Ingelheim Co., Ltd. booth. About 230 medical workers challenged the lung auscultation problem. Contrary to the results of the quiz, the satisfaction level was very high, and we were able to get a good reputation.
Overall satisfaction exceeded 90% for the sum of “Extremely satisfied” and “Slightly satisfied”.
This time, we used the virtual auscultation simulator iPax and the auscultation speaker Kikuzo to let everyone experience lung sound content.
The lung auscultation experience content consists of 3 questions of listening to sounds with an mp3 player and 2 questions (iPax) of the format of moving the stethoscope icon on the screen and solving the relationship between location and sound. ※Analysis results are described later.
In addition, we distributed these case explanations to those who experienced the lung auscultation content, and conducted a questionnaire for this corner.
Screen of lung auscultation content used in Booth
First, select your own “user attribute”. On the following page, there are 3 mp3 player questions, and after the 4th question, the question of operating the stethoscope icon on the screen. You can see questions unfolding in the video below.
Commentary with 2D barcode distributed at Booth (Q4 and Q5 only)
After their answering questions, we distributed case explanations (Q4 and Q5). The iPax auscultation content opens when the participant reads the two-dimensional barcode in the explanation with a smartphone. This allows them to hear the case’s sounds at home.
These cases were actually experienced by Dr. Takeshi Saraya (supervising doctor), and are published in the clinical magazine “Internal Medicine” published by Nankodo.
For reference IPF case used in Q5 Fine crackles are heard in the bilateral lungs and the bottom of the lungs.
Tap the chest or back auscultation area to move the chestpiece icon and listen to the sounds of that area. When listening to the sound, use the dedicated speaker Kikuzo or earphones.
stetho sound speaker Kikuzo
At Booth, we asked everyone to use Kikuzo, a special speaker for auscultation. A stethoscope is required when using Kikuzo. Physicians put on a stethoscope and are “ready to examine” (serious). That is also stated in the survey.

After the lung auscultation experience corner for everyone, we conducted a questionnaire survey using a tablet (out of 202 respondents to all questions, 141 responded to the questionnaire, 69.8%). Although filling out the questionnaire was voluntary, we were able to receive a large number of entries. ※Results are given below.

Analysis results of lung auscultation experience content
Q1-Q3 were questions to answer by listening to the sound of the mp3 player, and Q4-Q5 were questions to answer by operating the stethoscope icon on the screen. Their correct answer rate is as follows.
The correct answer to Q4 is “pulmonary hypertension”
Many pulmonologists chose “left heart failure”
The correct answer for Q5 is “IPF”
About half answered correctly, but many pulmonologists chose “COPD”
Auscultation site analysis
Analysis of the auscultation site
All data (n = 202) and pulmonologists data (n = 107) obtained this time were aggregated.
- Those who answered correctly auscultated the lung side and the base of the lung.
- Incorrect answers did not auscultate neither the lung side nor the base of the lung.
Below are examples of typical auscultation sites of doctors who took the quiz this time (those who answered incorrectly and those who answered correctly in Q5).
Incorrect answer: The part to be auscultated is higher than the point that should be auscultated.(Although it is possible to hear the consciousness of listening to the base of the lungs, that part is higher)
This is the recorded data of the pulmonologist. Looking at the auscultation site on the back, we can see that he listened just below the shoulder blade. Fine crackles are barely audible in this area. The part where the stethoscope should be placed (the base of the lung) is much lower than that.
Correct answer: Auscultation at the correct site.
This is the record of a resident who answered Q5 correctly. You can see that he is auscultating the lung side and the base of the lung in the correct area.

Q4（Pulmonary hypertension）Auscultation site analysis
Q5（IPF）Auscultation site analysis
About half of the attributes were “Pulmonologists”.
Approximately 70% of pulmonologists answered that they were “satisfied”.
Telemedica comment；About sound quality
While there is an opinion that “the sound source is not good”, there is also a description that “the sound was real”. You can see that this difference is the difference in volume. There was a lot of noise around the exhibition booth, so some people occasionally increased the volume of Kikuzo. It is understandable that when the volume was not returned to the original correct volume and another person listened to it as it was (at a high volume), they felt that the sound source was not good.
All the sound sources used this time were recorded by Dr. Takeshi Saraya from actual patients. We Telemedica processed the noise of the recorded sound sources and posted them on iPax.In addition, we have Dr. Saraya check the sound while using the Kikuzo, and adjust it so that it sounds the same as auscultating an actual patient.
More than 80% of pulmonologists answered that “the question was appropriate”
More than 90% chose “I want to use it again”
