 you know, larger than children's. The breath size, because with an adult, you're going to give a regular adult breath. For children, you have to pull back a little bit because the lungs are a little smaller, and you don't want to give the biggest breath you can because it'll bypass their airway, go to their stomach, and then even if they're nonresponsive, they'll vomit everything back up, and you still got to do CPR, so that's real gross. Yeah.
