Outline of Final Research Achievements

In disaster scenes, ambient noise causes significant restriction of emergency medical technicians’ physical examination, especially in auscultation. Traumatic pneumothorax is frequently found in the patients with chest injury. Among them make progress into a crucial state which was well-known as tension pneumothorax. I produced the respiratory-sound analyzing device before. Then, I had reported this device can detect pneumothorax in emergency department. However, it had a problem with collecting sound in loud environment. I added on the noise-suppression mechanism. This study was performed to evaluate whether this newly-improved device can detect pneumothorax in loud environment. This device was applied to the simulator mannequin who was set up under conditions of pneumothorax. Pink noise and traffic noise were used as loud environment presumptively. It had a good noise-suppression effect even on the loud environment over 70dB. This device might be available in prehospital scenes.
