Abstract

For the video laryngoscopes currently sold by four companies, performance was compared across a variety of characteristics. The results showed the FIBERTECH product to be the best when all aspects (resolution, distortion, chromatic aberration, angle of view, resolving power, focal length, illumination, etc.) were taken into account and an accurate, clear image could be obtained in practical use with this product.
