Under what condition is no Base contact necessary when considering termination of resuscitative efforts?

In the context of resuscitative efforts, the condition that indicates no Base contact is necessary is when there is persistent asystole accompanied by a capnography reading of less than 15 mm Hg. This scenario typically occurs in a situation where the heart is not generating any electrical activity (asystole) and the ineffective perfusion of blood is reflected in a low end-tidal carbon dioxide (ETCO2) reading.

A capnography reading below 15 mm Hg suggests that the patient is experiencing inadequate circulation and perfusion, indicating a very poor prognosis. In such cases, it is recognized that further resuscitative efforts are unlikely to be successful, and therefore, Base contact may not be warranted, as the established medical protocols support the discontinuation of resuscitation when these criteria are met.

This guideline is designed to prevent unnecessary prolongation of efforts in cases where chances of recovery are exceedingly low, thereby allowing crews to transition to other patients or needs without delaying care unnecessarily.
