The CLASSICS
COLD STEEL

The DL blade that everyone uses and has been around for a long time. Regardless of a Macintosh or Miller blade. It has been around a lot, and worked well but has limitations.
You can rock the Handle and Blade back when you panic and break teeth. Too much Brutane.
This is what is considered standard of care so far. Any third world country should have one.
Just because it works most of the time, should it be the only device we persue, a better product can be made.
Once affordable, video laryngoscopy will be the new standard of care.
If that COLD STEEL DL is all you have, be great at it. Try to be the best at it.
Position the patient correcty, not completely supine, and use you ELM well. You may only have one shot on successful intubation.
BAG MASK VENTILATION

There are those of you believe its the only device out there for fault of the training you received and your lack of reading.
Don't believe the hype.
Not all patients are Baggable to succesful oxygenation.
No one says it should be discarded. If that is all you have to protact that patient's airway and to keep viable oxygenation, you have no excuse not to be great at it.
It is a lost art, of doing it correctly. But even done right wll not prevent aspiration when a patient vomits.
BVM is much inferior to any SupraGlottic Device. Best to use a device that allows less soiling and overflow/aspiration into the glottic opening.
