Cyanosis in a Newborn Immediately after BirthA male neonate, weighing 3.9 kg, was delivered via Cesarean section at 39 weeks of gestation. He cried immediately after birth, but his whole body appeared blue and he had low muscle tone that did not improve with suctioning and stimulation. Blow-by with 100% oxygen was initiated, and pulse oximetry on his left hand measured 40%. What is the diagnosis?
