If the results are not good, you will inevitably have to consider using your mental senses.

Due to the lack of tools, he had to place his auricle against the patient's chest to listen. This inconvenience triggered his desire to work overtime to make an original stethoscope within three intercostal spaces.

[This will be included in their tuberculosis project funding later]

In order not to use his mental senses, Kraft carefully compared the results of auscultation and percussion, striving to be as close to the greatest degree of accuracy and reliability. However, the objective results still prove that the pursuit of new machines by the ancestors of radiology for many years is indeed due to the combination of machines and people.

There is an insurmountable gap between them.

Kraft still wanted to hold on for a while. He wrote down another auscultation result, moved to the other side, and leaned under the right shoulder blade, roughly at the seventh and eighth intercostal spaces. In the percussion just now, the performance was between skin and skin.

The sound between the drum and the empty urn indicates that there may be a cavity near the chest wall, and its size requires caution.
