General information on bronchoscopy

The first study of this type was dated back to 1897.At that time, the process itself was very dangerous and painful, because the patients used cocaine as an analgesic.Initially, the bronchoscope was used to remove foreign bodies.

In 1956 the bronchoscope, it may be said, was invented anew, it became absolutely safe, but at the same time it did not acquire a more familiar form for us, remaining firm.The first flexible bronchoscope was introduced after twelve years.And a decade later, modern developments allowed to increase the resulting image to identify diseases at earlier stages.

Bronchoscopy is a name derived from two Greek words: "inspection" and "breathing throat".The device is a specific system by which the respiratory organs are studied.Its diameter ranges from 3 to 6 mm, and the length is about 60 cm. As described above, the current bronchoscopes have special devices for displaying the image on the monitor, as well as auxiliary equipment.Video from the bronchoscope can be saved for comparison with further studies in order to study the progression of the disease or pathology.
