Q

How is cardiac arrest different in infants/children vs adults?

A

In infants and children, cardiac arrest is the end result of progressive respiratory failure/shock (asphyxial arrest), NOT a primary cardiac cause.

40%

A

Button batteries

63
Q

Aspiration of a foreign body into the right main bronchus leads to what effect during inspiration/expiration?

A
  • “Ball valve” effect
