When to begin CPR after a snake bite?

April 5, 2026

Quick Answer

Administer CPR only if the victim is unresponsive and not breathing after a snake bite. This can be the case if the snake is venomous and the victim has suffered a severe reaction. Do not delay CPR.

Recognizing a Snake Bite Emergency

If you suspect a snake bite, look for signs such as difficulty breathing, rapid heartbeat, and swelling at the bite site. These symptoms can indicate a severe reaction that requires immediate medical attention. If the victim shows no signs of breathing or a pulse, begin CPR.

Performing CPR after a Snake Bite

Start CPR by calling 911 or your local emergency number if you are in a safe location. If you are in a remote area, continue with CPR until help arrives. Begin compressions by placing the heel of one hand on the center of the victim’s chest, with the other hand on top. Push down 2-3 inches at a rate of 100-120 compressions per minute. After every 30 compressions, give two breaths. Each breath should last about one second and make the chest rise. Continue this cycle until medical help arrives or the victim shows signs of regaining consciousness.

Precautions and Considerations

When performing CPR after a snake bite, be aware of potential complications such as anaphylaxis or cardiac arrest. Antivenom may be delayed if the victim is receiving CPR. If you are trained in using an Automated External Defibrillator (AED), use it if the victim’s heart rate is less than 60 beats per minute.
