Emergency tracheal intubation in critically ill patients often fails for reasons that are partly anatomical and partly physiological. The problem becomes harder when the airway is contaminated by blood, vomitus, or dense secretions, because visualization degrades while oxygen reserve is already limited and aspiration risk is rising. Video laryngoscopy has improved first-attempt performance in many emergency settings, yet its optical advantage can collapse when the distal camera becomes obscured. At the same time, strategies for apneic oxygenation have shown mixed results in adults, and their effect appears to depend on patient selection, oxygen delivery site, and the pace of the procedure. This paper presents a structured  review of the contaminated airway as a distinct emergency phenotype and examines how two technical aims, preservation of visualization and maintenance of oxygen delivery during laryngoscopy, may intersect in a single device pathway. The discussion synthesizes clinical studies on first-pass success and repeated-attempt harm, literature on suction-assisted airway decontamination, randomized and simulation-based work on apneic oxygenation, and bench-oriented reports on oxygen delivery through laryngoscope-mounted channels. Particular attention is given to aerosol generation, aspiration dynamics, gastric insufflation risk, operator workload, and staged evaluation methods for device development. The central argument is limited and practical. A dual-function video laryngoscope blade that protects the lens while providing distal oxygen delivery is physiologically plausible and clinically relevant in a narrow group of high-risk cases, but any expected benefit should be treated as contingent on careful bench testing, simulation, feasibility work, and comparative clinical study rather than assumed from concept alone.
