Sterilization controls the microbial in this world
The answer is reproductive isolation. Reproductive isolation ensures members of different species do not produce offspring. In this case, geographical separation is ensuring that individuals from the two different populations are not able to mate with each other. Eventually, through different selective pressures, the two populations will diverge sufficiently in genotype to become distinctly different.
For a 2 year old patient who was severely dyspneic and now unresponsive and no longer breathing, you will instruct your EMT to insert an OPA and begin give positive pressure ventilations with a BVM with 100% O2 to the patient. Palpate for a pulse and if <10 seconds you cannot feel a pulse, you will begin chest compressions.
The good thing about respiratory codes in children is that they normally always code due to lack of oxygenation. Once they are finally re-oxygenated, they will typically come around with better vitals.
