O+ blood is very important as a (mostly) universal red blood cell type. This blood type can be used in emergency situations such as traumatic bleeding or other types of emergency transfusions.

O positive blood can't be used universally because it has the Rh factor, but it is compatible with all positive blood types including O+, A+, B+, and AB+. Since over 80% of the population has a positive blood type, type O positive blood is in high demand.Jan 8, 2021
Blood O+ can donate to A+, B+, AB+ and O+ Blood O- can donate to A+, A-, B+, B-, AB+, AB-, O+ and O- Blood A+ can donate to A+ and AB+Nov 22, 2016

In an emergency, it is the blood product of choice. For example, just one car accident victim can require up to 100 units of O neg. Meeting the demand for O negative blood is always a priority for the Red Cross. 5 O negative is the first blood supply to run out during a shortage due to its universality.
Latest studies have shown that someone in the US needs a blood transfusion every 2 seconds each day in the United States. The average person can only donate 1 pint of whole blood in a single donation and the shelf life is 42 days, which is why the need to keep replenishing the supply to meet demand is great.

In addition to the A and B antigens, there is a protein called the Rh factor, which can be either present (+) or absent (–), creating the 8 most common blood types ( A+, A- , B+, B- , O+, O- , AB+ , AB- ). Click on a blood type below to learn more.
Blood types are determined by the presence or absence of certain antigens – substances that can trigger an immune response if they are foreign to the body .
