Airwaves Episode 2

Videolaryngoscopy is now a widely available tool for airway management, yet airway practitioners continue to debate its exact role, the evidence for its benefit over direct laryngoscopy and the optimal technique for its use.

Leading experts in videolaryngoscopy, Tim Cook (anaesthetist & intensivist) and George Kovacs (emergency physician), discuss evidence, opinion and controversies and take questions from the online audience.
