What should be done after administering a drug via the ETT during CPR?

Administering a drug via the endotracheal tube (ETT) during cardiopulmonary resuscitation (CPR) necessitates immediate steps to ensure the medication can be effectively utilized. After delivering a medication through the ETT, it is critical to instill a flush, typically around 5cc of sterile normal saline, to facilitate the delivery of the drug into the lungs and enhance its absorption into the bloodstream.

Following the flush, providing ventilations is essential, especially in a scenario where the patient is not breathing on their own. The follow-up breaths help to deliver the medication to the alveoli, where it can be absorbed more effectively, thus maximizing its therapeutic effect during the resuscitation effort.

This step is vital as it enhances the likelihood that the drug will circulate and achieve the desired physiological effect, which is a cornerstone of effective resuscitation practices.
