Randomized Controlled Trial Comparative Study
In flight auscultation: comparison of electronic and conventional stethoscopes.
The ability to auscultate during air medical transport is compromised by high ambient noise levels. The aim of this study was to assess the capabilities of a traditional and an amplified stethoscope (which is expected to reduce background and ambient noise) to assess heart and breath sounds during medical transport in a Falcon 50 plane. ⋯ Practicians in Falcon 50 are more able to hear cardiac sounds with an amplified than with a traditional stethoscope, whereas there is no significant difference concerning breath sounds auscultation.

Advances in analysis of electrical signals have now made it possible to create a handheld electroencephalogram (EEG). ⋯ The automated EEG device may be a useful tool for identifying brain abnormality in the emergency department.
