The Airway Cam Direct Laryngoscopy Video System. The Airway Cam imaging system was invented by Dr. Levitan in 1994 when he was an emergency medicine resident at Bellevue Hospital in NYC. Recognizing the challenges of skill acquisition and the lack of imaging, he developed a means of displaying direct laryngoscopy as seen by the operator. Bimanual laryngoscopy is known to improve visual field during intubation. This procedure might reduce laryngeal trauma during intubation and therefore reduce the incidence or degree of post-operative sore throat. This is the first prospective, double-blinded, controlled study, which is focused on the effects of bimanual laryngoscopy on first 24 POGO scores with bimanual laryngoscopy were higher compared to cricoid pressure (mean difference 20, 95% CI 17 to 22) and BURP (mean difference 21, 95% CI 19 to 24). Among laryngoscopies with no Bimanual laryngoscopy that involves operator-directed manipulation of the thyroid cartilage has been introduced [6] and has been suggested to be more effective than cricoid pressure and BURP for Laryngeal view during laryngoscopy: a randomized trial comparing cricoid pressure, backward-upward-rightward pressure, and bimanual laryngoscopy. Richard M Levitan, William C Kinkle, William J Levin, Worth W Everett Annals of Emergency Medicine 2006, 47 (6): 548-55 Others have done ELM by modified bimanual laryngoscopy, which involved direct guidance of the assistant's hand by a laryngoscopist to optimize laryngeal exposure. The authors have found that ELM done by modified bimanual laryngoscopy is more effective for obtaining the optimal laryngeal view than conventional ELM.

Bimanual laryngoscopy vs. Cricoid vs. BURP Levitan RM, Kinkle W, Levin W, Butler K. Annals EM 2006; 47: 548-55. - 104 participants, 106 cadavers - 1530 laryngoscopies - POGO scores to report laryngeal view - Improved exposure (Bimanual vs. CP vs. BURP - all p<.0001) Finally and probably what took ELM out of the realm of anesthesia and into the EM world, was Levitan's study in 2002. This study, which popularized the term "bimanual manipulation," enrolled patients subjected to intern laryngoscopy and demonstrated that the percentage of glottic opening (POGO) score was improved in just about every attempt. ELM is a simple and very effective technique for improving laryngeal view during laryngoscopy by novice intubators and a validated means of assessing larynGEal view (percentage of glottic opening] score. STUDY OBJECTIVE We perform a videographic analysis of external laryngeal manipulation (ELM) by novice intubators using a direct laryngoscopic imaging system and a validated means of assessing What We Do. We pioneered dynamic imaging of direct laryngoscopy with the Airway Cam Direct Laryngoscopy Video System in 1994 . Our educational products have been used in 4,000+ institutions across 30 countries. We demystify airway anatomy and education through intensive imaging, anatomic education, and hands-on training with cadavers and unique
