Be aware that the invisible and mortal carbon monoxide gas can kill very quickly because it competes with oxygen in binding with hemoglobin ( our blood cells), and it binds with hemoglobin, and guess who wins the binding? Yes, believe it or not, Carbon monoxide wins over oxygen. Hemoglobin and carbon monoxide have a strong attraction for each other.
Knowing that is very important to save yourself during a fire or in the event of a suspicious leaking gas. If you see people fainting on the floor, never enter the area unprepared. Make sure to breathe in with an oxygen tank. Now you're safe and good to go. Now that you have your oxygen tank ready, so you breathe oxygen through your oxygen mask, you can go and start rescuing people.
PROTECT YOUR OWN LIFE BEFORE TRYING TO RESCUE OTHER PEOPLE. Be prepared with oxygen tanks, know how to check if it's empty or full, have all the hook-ups ready, an oxygen mask, tubes, and the necessary tools to connect.
If you feel your life is in danger because you were breathing carbon monoxide, so you probably have carbon monoxide poisoning, go to an emergency department and they will collect your blood and see how much the danger is for carbon monoxide poisoning. Get a BLOOD TRANSFUSION, get your own blood type, and the same Rh. If you are Rh negative, only receive Rh negative. If you are O negative, receive only O negative, and so on. Some blood types are compatible to receive different blood without harm, usually, you receive your own type.
Breathing O2 helps, but O2 alone DOES NOT FIX THE PROBLEM. REMEMBER THE CARBON MONOXIDE IS ALREADY BOUND WITH YOUR BLOOD CELLS FOR THE NEXT THREE MONTHS (BLOOD CELL LIFETIME). BREATHING OXYGEN MAKES LITTLE DIFFERENCE IF THE LEVELS OF CARBON MONOXIDE ARE TOO HIGH, GET A BLOOD TRANSFUSION AS SOON AS POSSIBLE!!!
