Which medications, and at what dose, can be adminstered via the endotracheal tube during cardiac resuscitation?

NAVEL: naloxone, atropine, vasopressin, epinephrine, lidocaine

While endotracheal administration of these resuscitation drugs is possible it is suboptimal relative to IV or IO drug administration because it offers less predictable drug delivery and pharmacologic effect.

While the optimal endotracheal dose is unknown, the typical dose given is 2 - 2.5 times the recommended IV dose. For epinephrine it may be as high as 3 - 10 times. The medication should be diluted in 5 - 10 cc of water or normal saline and then injected directly into the endotracheal tube.
