How does defibrillation fit into the equation of naloxone administration? Which takes precedence; naloxone or defibrillation and/or CPR?
The response to this question is dependent on the level of training that the responding individual has had.
“As per guidance provided by Ontario’s Opioid Emergency Task Force, all publicly funded naloxone kits contain an instructional insert that advises that if an opioid overdose is suspected/known, the administration of naloxone comes before the provision of chest compressions/rescue breathing. These instructions are intended for lay persons who are responding to an opioid overdose, the majority of whom are not formally trained in first aid, nor have access to a defibrillator. Lay-responder training is designed to be brief and low-threshold.”- Ministry of Health
As mentioned above, the lay individual often does not have formal first aid training or access to an automated external defibrillator (AED). Many overdoses occur in the home or on the street where an AED is not easily accessible. In addition, the tools or equipment that the lay individual has access to is different than what trained medical professionals have (e.g., artificial airways and manual ventilation tools) to improve airway functioning. Naloxone training was designed with these considerations in mind so it is recommended that the lay individual administer naloxone prior to attempting CPR.
Agencies and/or programs that have procedures or protocols that vary from the order followed in the community naloxone training (i.e., step 3- administer naloxone; step 4- provide chest compressions and rescue breaths) should follow the recommended procedures or protocols of their agency and/or program (i.e., defibrillation first).
I am not formally trained to do chest compressions and/or rescue breaths. Should I administer these even though I do not have formal training?
Individuals without formal training but who are comfortable to do so can administer chest compressions and/or rescue breaths. Step 2 of responding to an opioid overdose is calling 911. After calling 911, dispatchers can talk the responder through chest compressions and rescue breaths for cardiac arrest while on the phone if the person responding is willing. Responders are protected by
The Good Samaritan Act if injury should occur to the unconscious person while providing life-saving efforts.
Do you have any resources or additional information on providing chest compressions and/or rescue breaths?
If you have determined that a person is unconscious and not breathing, begin CPR immediately. Push hard and fast on the chest, and perform cycles of 30 chest compressions to two rescue breaths.
Below are a few resources on providing CPR:
