Apgar score is a system of medical assessment that is used to measure the health of a newborn baby. It is named after its creator, Dr. Virginia Apgar, who developed the system in 1952. The Apgar score is based on five criteria: heart rate, respiratory effort, muscle tone, reflex irritability, and color. Each criterion is assessed on a scale of 0 to 2, with a total score ranging from 0 to 10. A score of 7 or higher is considered normal, while a score of 4 or lower is considered indicative of asphyxia. Asphyxia is a condition in which the body does not receive enough oxygen, which can cause serious complications, including brain damage and death. Therefore, it is important to recognize and treat asphyxia quickly.
