Is video laryngoscopy superior to direct laryngoscopy for the endotracheal intubation of cardiac arrest patients?

BEEM Bottom Line

Why is this study important?

Evidence indicates that pauses in compressions (including those for intubation) during cardiopulmonary resuscitation (CPR) are associated with lower survival.[1] If video laryngoscopy (VL) has a better success rate, is faster, and can be accomplished with shorter/no pauses in compressions, than direct laryngoscopy direct laryngoscopy (DL), then use of VL may lead to higher survival for patients.

Which, if any, threats to validity are most likely to have an impact on the results and how?
