A abrupt run down of the fiber optic cable tester. Discount-Low-Voltage.com
Some times I'm using the happy accident fiber optic tester for multimode and singlemode fiber optic
If this is anything like the results I've seen before, it means that their is filtration of touch off into the fibre path. Can be caused by breached insulation.
The Bonfils intubation fiberscope has a limited top angle upward 40 degrees and requires the entry retromolar in the hypopharynx. These factors may make its use less desirable in the management of difficult intubation, for most anesthesia providers are well versed in the midline rather than oral intubation lateral retromolar approach.
The Centre for Advanced Technology and Telemedicine at the University of Nebraska Medical Center has developed a novel endoscope with a curve more anteriorly 60 degrees to allow easy insertion and intubation midline.The aim of this study was to evaluate the fiberscope novel from the Bonfils intubation fiberscope, in terms of use and function in the difficult airway intubation.
