An RT working in a small, rural hospital is called to the
emergency department, where a patient is in cardiac arrest. The RT is able to
intubate and ventilate the patient, using a bag-valve device with 100% O2.
Nurses are performing cardiac compressions and attempting
unsuccessfully to start a peripheral IV line. The ECG monitor reveals a fine VF
pattern. Electrical defibrillation is unsuccessful on the first attempt, and
five cycles of 30 compressions to 2 ventilations are in progress. Immediate
administration of epinephrine without interrupting CPR is indicated before or
after the next shock. Attempts to secure an IV line continue to be
unsuccessful. What action is appropriate at this time?
