Question: This question is a follow-up to clarify between two questions previously asked- specifically, regarding advanced resuscitation in the setting of DNR, and treatment of FBAO in the setting of DNR. In the most recent question the DNR validity form is quoted as stating that chest compressions should not be initiated on patients with a valid DNR, while in the earlier question it was stated that DNR does not preclude treatment for choking. Should we come across this situation, would we then only administer ‘Heimlich’-like abdominal thrusts and not proceed to chest compressions when the patient goes unresponsive, or should chest compressions be initiated until the heart has arrested and then discontinued (i.e. not proceeding to true CPR)?
