That's what is called competitive enzymatic regulation. If there are more of that substance than the enzyme substrate, then most of the enzyme, if not all depending on the substance's concentration, will be inhibited on its action. If there are more substrate then the competitive substance, the expected reaction for that enzyme will happen at an expected rate. If the ratio substrate:substance is 1:1 then the reaction enzyme-substrate is very slowed down.
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.
