Besdata Video Laryngoscope: The Ultimate FAQ Guide

Video laryngoscopes are an advanced endoscopy tool.

Medical practitioners use them, mostly ENT specialists, to view the larynx, vocal cords, and glottis. Anaesthologists also use this device as an intubation tool to keep the airways open during surgeries and other medical emergencies.

Note: A video laryngoscope comprises a handle that acts as a light source and several interchangeable blades.

It also incorporates a camera at the distal tip of the blade and a screen. These allow indirect visualization of the throat and larynx or the voice box.

This guide provides more insight into video laryngoscope, especially Besdata video laryngoscope. If you are looking for a quality video intubation tool, read on.

1.  What Is The History Of Laryngoscope?

Video laryngoscope

Video laryngoscope

The history of laryngoscopy dates back to the 1700s.

The development began with indirect laryngoscopy techniques where various light sources and mirrors were used to examine the larynx.

Some historians credit Benjamin Gay Babington with this early development having invented the first laryngoscope (the Glottiscope) between 1794 and 1866.

But medical journals also cite Manual Garcia as the pioneer of indirect laryngoscopy. It is believed that Garcia, then a voice professional in London, was reportedly the first person to visualize a functioning glottis and larynx using two mirrors and sunlight.

In both cases, the technique has known several advances, mainly concerning light sources and blades modifications.

Towards the end of the 19th century, Alfred Kirsten introduced the very first form of direct laryngoscopy. Kirsten borrowed ideas from esophageal endoscopy to develop the “autoscope,” the first known instrument for direct visualization of the larynx. He used a headlamp for light.

Later, Chevalier Jackson made some improvements to the autoscope, which included using a tungsten bulb for lighting.

Since Kirsten’s invention, most observations of the glottis and larynx have been made under direct laryngoscopy. However, the technique was marred with several challenges, mainly inadequate glottis exposure.

It is for this reason that the industry decided to redevelop, or return to indirect laryngoscopy, currently video laryngoscopy.

The first true video laryngoscope was built in 1999, following Dr. Jon Berral’s design of a video laryngoscope with a straight screen camera in 1998. However, John Allen Parcey’s glidescope became the first commercially available video laryngoscope in 2001.

Today, several types of video laryngoscopes are available. But some practitioners still use direct laryngoscopes while others use both direct and indirect tools under varying circumstances.

2.  Why Is Video Laryngoscope Better Than Conventional Laryngoscope?

Conventional laryngoscope

Conventional laryngoscope

The debate between video laryngoscopes and conventional laryngoscopes has existed since the 19th century.

But the inherent limitations of conventional laryngoscopes have made the video alternatives fundamental in the practice of airway management and intubation. This is due to the many advantages of video laryngoscopes, including:

  • Better vision of the glottis and larynx
  • Greater chance of success in airway management and intubation
  • Reduced risks associated with close patient contact
  • Reduction of intubation attempts, especially in patients at high risk of complications, e.g., obese patients.
  • Increased patient safety due to a lower risk of laryngeal trauma, as these devices require relatively less force to intubate.
  • Ability to look around corners. Conventional laryngoscopes do not allow operators to see beyond the line of sight.

Compared to conventional laryngoscopes, video devices are also useful for education and sharing medical information. It allows watching the ongoing intubation processes and saving them for later use.

  • Intensive care applications such as a backup to endotracheal extubation support strategy.
  • Critical care in air transport applications
  • Teaching airway anatomy
  • Pediatric applications, i.e., intubation of underweight neonates
  • Facilitate insertion of other medical devices such as Nasogastric Tubes, Feeding Tubes, and transesophageal echocardiographic probes

7.  Can The Besdata Video Laryngoscope Be Used For Difficult Airways?


Besdata video laryngoscope has several valuable features for intubation in patients with difficult airways.

As mentioned earlier, these devices are designed with an easy-to-grip ergonomic handle that requires less force to operate. This feature helps deal with trauma cases and complications in anticipated difficult airways.

In addition, the anti-fog camera and the blade function also allow the device to resist fogging and bloody contamination. This allows for an unobstructed view allowing operators to perform difficult intubations confidently.

Note, however, that in cases of unexpected difficult airways, tracheal intubation with video laryngoscopes remains a challenge.

In this case, physicians are advised to adhere to specific intubation strategies, such as the ASA guidelines for difficult airways. This will help reduce complications in unanticipated and emergency difficult airways. Tools that make tracheal intubation easier are also recommendable in such cases.

8.  What Is The Difference Between Standard Geometry Video Laryngoscope And Hyper-angulated Video Laryngoscope?

Standard geometry vs hyper-angulated video laryngoscope blades

Standard geometry vs. hyper-angulated video laryngoscope blades

As you know, video laryngoscope blades come in various shapes and sizes. These varieties include blades with a standard or hyper-angulated geometry.

The main difference between the two is that standard geometry blades maintain the shape of Mackintosh or miller blades. On the other hand, hyper-angulated blades have a more pronounced curvature.

Another difference is that standard geometry video laryngoscopes can be used for direct and indirect visualization. Conversely, a hyper-angle laryngoscope can only be used for indirect visualization.

In addition, during intubation, hyper-angulated blades are used with a rigid stylet. On the other hand, blades with a standard geometry allow the use of a bougie where necessary.

Besdata video laryngoscope mostly uses blades with standard geometry. The advantage of this type of blade is that it offers a higher first-attempt success rate than laryngoscopy using hyper-angled blades.

Medical reviews also suggest that passage of the endotracheal tube tends to be faster and less cumbersome when using a standard geometry blade.

Pound for pound, clinicians can use whatever type of blade they prefer. However, it is recommended that the selection be strictly based on the characteristics of the respective patient requiring intubation.

Trouble getting ET tube to the mouth –          Try inserting the video laryngoscope slightly  left of the midline to leave enough space to the right of the device to get the tube into the mouth

–          Move the device to the left of the mouth

–          Move the handle to the left to allow passage

“best view” is not sufficient for intubation Try backing up the scope a little to widen the  field of view
Issues with maneuverability Hold the tube closer to the connector
No images appear on the display monitor Recharge or replace the batteries
Blurry images –          Withdraw the blades to check that the image is clear

–          Make sure there is no fog on the camera or the blades. Blood contamination could also be a problem, in which case you will only need to retract the blades to clean and aspirate the blood before intubating.

–          If the problem persists, replace the blade
