Video-based laryngoscopes having an external centrally located channel coursing from the handle to a curved blade configured to deliver an ETT to a trachea as visualized by a non-removable, or alternatively, a removable video camera and lighting unit located beneath the external channel. The channel laryngoscope may be made for single use in a patient and discarded, or be processed for re-use. Alternatively, the channel laryngoscope may have a removable video camera and lighting member located within an internal chamber that runs parallel with the external channel. In another embodiment a laryngoscope adapter may be detachably affixable to the channel laryngoscope equipped with the non-removable camera to provide a decontaminated or sterile surface to permit re-use of the channel laryngoscope without having to undergo washing or decontamination procedures.
