APGAR Scoring — Interpretation and Clinical Significance

A preterm infant (32 weeks gestation) born to a mother with prolonged rupture of membranes has an APGAR score of 3 at 1 minute (HR 50 bpm, no respiratory effort, limp, no response to stimulation, pale). Immediate resuscitation has been initiated with positive pressure ventilation and chest compressions. After 15 seconds of adequate ventilation and compressions, the heart rate remains 40 bpm. What is the most appropriate next step?

Two newborns are assessed at 5 minutes of life. Infant A (term, vaginal delivery) has APGAR 8 with pink body, blue extremities, spontaneous cry, and good muscle tone. Infant B (term, vacuum-assisted delivery) has APGAR 6 with pale body, cyanosis, weak cry, and decreased muscle tone. Which single feature best discriminates the clinical urgency and risk of adverse outcome between these two infants?

A term newborn delivered vaginally has an APGAR score of 3 at 1 minute (poor respiratory effort, weak cry, cyanosis, hypotonia, bradycardia). Resuscitation is initiated. At 5 minutes, the score improves to 6. Which investigation is most appropriate to assess the severity of perinatal asphyxia and guide prognosis?

Among newborns with persistently low APGAR scores (≤3 at 5 minutes) despite resuscitation, which is the most common underlying cause requiring urgent investigation?

A full-term female neonate is delivered vaginally after an uncomplicated pregnancy and labour. At 1 minute after birth, the baby is noted to be cyanotic with slow, irregular respirations. Heart rate is 95 bpm. She responds to tactile stimulation with a grimace. Limbs show some flexion. What is the APGAR score at 1 minute, and what is the most appropriate immediate management?
