Drug therapy Epinephrine Note:   Available evidence suggests that the routine use of atropine during PEA or asystole is unlikely to have a therapeutic benefit. For this reason, atropine has been removed from the Cardiac Arrest Algorithm. To date no placebo-controlled trials have shown that administration of any vasopressor agent at any stage during management of VF, pulseless VT, PEA, or asystole increases the rate of neurologically intact survival to hospital discharge. There is evidence, however, that the use of vasopressor agents is associated with an increased rate of ROSC.

Methods of Confirming ET tube Placement Direct cord visualization End-tidal CO2 monitor Yellow- yes, tube is correctly placed Tan- think about it Purple- problem with tube placement Bilateral breath sounds CXR Continuous waveform capnography Note:   Continuous waveform capnography is recommended in addition to clinical assessment as the most reliable method of confirming and monitoring correct placement of an endotracheal tube (Class I, LOE A). Providers should observe a persistent capnographic waveform with ventilation to confirm and monitor endotracheal tube placement in the field, in the transport vehicle, on arrival at the hospital, and after any patient transfer to reduce the risk of unrecognized tube misplacement or displacement Continuous Waveform Capnography Persistently low PETCO 2 values (<10 mm Hg) during CPR in intubated patients suggest that ROSC is unlikely If PETCO 2 is <10 mm Hg, it is reasonable to consider trying to improve...
