Final answer:
The percentage of newborns requiring extensive resuscitation to survive cannot be determined precisely, as it depends on individual circumstances. The Apgar scoring system is used to assess the need for medical assistance in newborns.
Step-by-step explanation:
The percentage of newborns that will require extensive resuscitation to survive can vary depending on various factors. One way to assess the need for resuscitation is by using the Apgar scoring system. This system evaluates five criteria - skin color, heart rate, reflex, muscle tone, and respiration - and assigns a score of 0, 1, or 2 for each criterion. Scores are taken at 1 minute and 5 minutes after birth.
A baby with a total score below 5 indicates an emergency situation, while scores lower than 7 at the 5-minute mark may indicate the need for medical assistance. However, it's important to note that these scores are not necessarily indicative of the percentage of newborns requiring extensive resuscitation, as not all newborns will have low scores. Scores of 8 or above are considered normal.
Therefore, it is not possible to provide an exact percentage of newborns requiring extensive resuscitation to survive, as it can vary based on individual circumstances and factors involved. However, the Apgar scoring system is a valuable tool used to assess the need for medical assistance in newborns.
