Apgar score

Virginia Apgar invented the Apgar score in 1952 as a method to quickly summarize the health of newborn children. Apgar was an anesthesiologist who developed the score in order to ascertain the effects of obstetric anesthesia on babies.

The Apgar scale is determined by evaluating the newborn baby on five simple criteria on a scale from zero to two, then summing up the five values thus obtained. The resulting Apgar score ranges from zero to 10. The five criteria are summarized using words chosen to form a backronym (Appearance, Pulse, Grimace, Activity, Respiration).
