Rescuer 1 (Compressions):

• Begin chest compressions right away, kneeling at the victim’s side.
• Push down at least 2 inches—but no more than 2.4 inches—at the center of the chest.
• Compress at a rate of 100 to 120 per minute in a cycle of 30 compressions to 2 breaths.
• Let the chest fully rise between each compression.
• Switch roles every 5 cycles or roughly every 2 minutes to avoid fatigue.

Rescuer 2 (Airway and Support):

• Activate the Emergency Response System (call 9-1-1) and retrieve the AED.
• Keep the airway open and deliver 2 breaths after every 30 compressions using a bag-mask.
• Offer encouragement to Rescuer 1 and ensure compressions remain strong and effective.
• If more team members arrive, they can assist with ventilation and AED setup.
  
  

Using a Bag-Mask Device
A bag-mask device is common in clinical settings and is used for assisted ventilation. It includes a face mask and a squeezable bag, and connects to high-flow oxygen.

• Choose a mask that covers both the nose and mouth to create a proper seal.
• Avoid pressing the mask down, lift the face into the mask instead.
• Attach the mask to the bag, then to oxygen at a flow of 15 liters per minute.
• Inflate the bag fully before use.
• Open the airway using the head-tilt, chin-lift motion.
• Give 2 rescue breaths, each lasting 1 second.
• Watch for the chest to rise and fall.
• If the chest doesn’t rise, check for blockages, ensure the seal is secure, and try again.
