I'm pretty sure you can do it on both but a child would be safer to do cpr on to me because, on an infant their insides are still really fragile so you don't wanna press to hard :)

Most likely... You die. Getting shot in the chest is a very devastating MOI (mechanism of injury). Three main issues can arise as a result of just one well placed GSW; If the projectile hits the heart othpericardium fatal bleeding into the sack or complete destruction of thud organ can result in death really quickly. Aditionally there are several major blood vessels exist in the chest, including the aorta, which if perforated can cause axanguanation (bleeding out within minutes). If one is lucky the the bullet would hit the lung, which is not an instant death sentence, however that's where luck will end, as a puncture of the plural space surrounding the lungs would become compromised, allowing are into the cavity reducing oxygen intake gradually; called a tension pneumothorax.
Answer:
The best response to the question: Brain blood flow autoregulation:___, would be, B: causes constriction of cerebral blood vessels in response to a drop in systemic blood pressure.
Explanation:
The maintenance of blood pressure for the brain is vital. This organ alone consumes around 20% of the total amount of oxygen available in the body, and whenever conditions change for the worse, the brain will generate actions to ensure that its blood flow is maintained. To do this, the brain has the capacity for autoregulation, meaning, the organ itself has the means to control the process, even if the rest of the body cannot. To do this, the brain resorts to several different mechanisms, and as of today, scientific research cannot assure that one mechanism is primary over others. What it is known for sure is that changes in systemic pressure drive the brain to initiate mechanisms of autoregulation to ensure that the flow, and pressure for nutrition and gas exchange in the brain, will be maintained. That is why the answer is B.
