To support a choking infant, Fernando held the infant, face down, with one hand, placing her torso on his forearm and his forearm on his thigh. He slapped the infant five times between her shoulder blades with the heel of his other hand. When this did not expel the object, he turned her face up, supporting the back of her head with his hand. He did 5 two-finger chest thrusts, but the infant became unresponsive. Fernando then held the infant in his arms until the paramedics came. What was Fernando’s mistake? He should have done the seven-and-seven approach. He should have given the infant CPR when she was unresponsive. He should have done chest thrusts first, and then back blows. He should have rolled the infant on her side so the object could be expelled.
