APGAR Score at Birth
The APGAR test is a rapid head to toe newborn assessment tool. EMTs take the newborn’s APGAR score at one minute and five minutes after delivery to quickly determine if any treatments need to be done.
The APGAR test is made up of 5 categories that each have possible scoring from 0-2. (So an APGAR score of 2 in each category will equal a total score of 10 points.) APGAR stands for each of the five categories newborns are tested on, these are listed below.
The total APGAR score can range from 0-10 points. If the newborn’s APGAR score is 7 or more points, they will only need routine care (blanket for warmth, etc) and another APGAR test 5 minutes after being born.
If the newborn has an APGAR score of 4-6 points they need some assistance from the EMT (suction mouth, stimulation, etc) and a retest to check for improvement 5 minutes after being born. If the newborn has an APGAR score of 3 or less they need immediate Advanced Life Support initiated.
A low APGAR score at birth doesn’t mean the baby will have chronic health issues. It’s common for a newborn to score less than 10 on their first APGAR score and then go on to be healthy and happy babies.
The APGAR acronym stands for: APGAR
