O group because O blood is a universal donor but only can receive type O blood for their body
An exact year is impossible to identify but the most blood transfusions likely occurred during wars due to mass casualties.
It depends on the state/facility. Most LPNs are not allowed to perform blood transfusions, that is a task that cannot be delegated to ancillary staff, or those that are not registered nurses.
Type O blood group would be in higher demand than other types of blood because first of all it is the most popular blood group and secondly because type O negative can be used in emergency blood transfusions to all other blood groups.
Blood groups are divided to classify individuals based on the presence or absence of specific antigens on the surface of red blood cells. This classification is crucial for safe blood transfusions, organ transplants, and understanding certain medical conditions. The most well-known systems are the ABO and Rh systems, which help prevent adverse reactions during transfusions and ensure compatibility between donors and recipients. Furthermore, blood group can also influence susceptibility to certain diseases and responses to medications.
An acute febrile reaction is the most common adverse reaction to a blood transfusion. This is typically treated with tylenol.
Although transfusion errors are only a small percentage of all medical errors reported in North American hospitals, they are the most common cause of serious mortality and morbidity associated with blood transfusions
O negative blood group is rare because it lacks the A, B, and Rh antigens present in most other blood types. Only 7% of the population has O negative blood, making it less common and in high demand for blood transfusions since it can be safely transfused to individuals with any blood type.
The blood group that is most common is 0+. It is a universal blood type.
O+ is the most common blood type. Thus, it is the type needed most often by hospitals for blood transfusions. AB- is the rarest of the "common" blood types, so your friend is mistaken.
The most common blood group most probably is O+ or even B+
O blood types are the most common, and therefore are needed most often by hospitals in life saving emergency blood transfusions. There is high demand for type O donors because of this.
O positive is the most common blood group in India.
