To the Editor,

The ability to teach direct laryngoscopy effectively poses a challenge to medical educators.1 A key difficulty is the inability of the instructor and trainee to visualize the laryngoscopy field of view simultaneously. The ability of the instructor to see what the trainee is seeing would allow for real-time feedback without interference with the laryngoscopy. This concept was previously described by Levitan who invented a head-mounted video system connected to a monitor for real-time display.2 Nevertheless, the costs and technical setup associated with Levitan’s “Airway Cam™” likely limited its widespread use as a teaching tool. To address these limitations, we have created an alternative solution that is simple, portable, cost effective, and as unobtrusive to the trainee as possible.

A JVC ADIXXION GC-XA2 camera (JVC Canada) was used to stream a high resolution video to a fourth generation iPad (Apple ®Canada) using Wi-Fi connectivity. The camera was mounted on a goggle...
