In an APGAR score, what is assessed as 'reflex irritability'?

In the context of the APGAR score, 'reflex irritability' refers to the newborn's response to stimuli, which is assessed to determine how well the baby is transitioning to extrauterine life. Specifically, it evaluates how well the infant reacts to various stimuli, such as a gentle slap on the back or a suctioning of the airways. A strong response indicates that the nervous system is functioning well, which is an important marker of the baby's overall health and ability to respond to the environment.

The focus on this parameter underscores the importance of neurological function in newborns and provides insight into their ability to feel and react to sensory input. A higher score in this category reflects good adaptiveness and responsiveness, which are critical for survival and development. Other aspects of the APGAR score, such as breathing, heart rate, and muscle tone, also contribute to assessing a newborn's health, but reflex irritability specifically targets how the baby responds to external stimuli.
