AED has a Glidescope video laryngoscope available in the resus area.
This is a step-by-step training video for using the Glidescope.
The technique of use is different from the Macintosh blade. The video link goes through the basic steps.
4 steps to remember –
1) Look at the mouth (to insert the blade in the MIDLINE)
2) Look at the screen (to get the laryngeal view)
3) Look at the mouth (to pass the ETT into the back of the mouth)
4) Look at the screen (to pass the ETT through the cords)
