Overview
Laboratory testing should be ordered to rule out hyperkalemia, hypoxia and acidosis (ABG), exsanguination (hematocrit).
Laboratory Findings
Laboratory findings consistent with the causes of pulseless electrical activity include:
- Hyperkalemia should be ruled out[1]
- A stat arterial blood gas will provide information regarding the presence of hypoxia and acidosis
- A stat hematocrit can also be checked on the arterial blood gas to evaluate the patient for exsanguination
- Any patient with drug overdose can undergo a rapid urine or blood screen to identify the cause of the problem.
