Since we started using the CMAC videolaryngoscope we have been collecting useful airway videos for education. You can find these videos on this page.

We’ll be adding to this page regularly so check back for new videos.
The first (very short!) shows soot, on the face as the CMAC is inserted and on the cords at laryngoscopy.
The second shows very mildly sooty snot in the airway of a patient with 35% TBSA burns just before the epiglottis is visualised. Sooty snot on nose-blowing was part of the rationale for intubation in this patient.
This video shows the appearance of a single (right sided) NPA during passage of the CMAC laryngoscope through the oropharynx.
Double (Bilateral) NPA
This video shows the appearance of bilateral NPAs during passage of the CMAC laryngoscope through the oropharynx.
This video shows the appearance of a denture plate during passage of the CMAC laryngoscope through the oropharynx. This is not secured and should be removed; it’s easy to see how it could cause a complete airway obstruction.
Blood in airway + CPR = no CMAC view!
In this video, the presence of blood in the airway in combination with the use of the LUCAS device to provide CPR means that the view is totally lost when the blood hits the camera.
What the oesophagus looks like
It can be hard to differentiate oesophagus from trachea at laryngoscopy. This short video shows some friable and hard to identify structures. The hole that eventually appears has the typical appearance of the oesophagus – the trachea is not seen until the final seconds.
What an NG tube looks like
This short video shows the appearance of a nasogastric tube at laryngoscopy.
The effect of a dry tongue
This video demonstrates how a dried tongue can hamper laryngoscopy attempts by sticking to the laryngoscope. Gently moving the blade forward should get you the view you are looking for.
Using suction and ELM to improve your view
This video nicely shows how suction and external laryngeal manipulation (ELM) can improve your view to facilitate intubation.
Severely soiled pharynx and trachea at laryngoscopy. Note soiling distal to the vocal cords and the absence of a gastric tube at this point.
