A newborn presents with central cyanosis and a heart rate of 90 beats per minute. What is the best course of action?

In the scenario presented, the newborn is exhibiting central cyanosis and has a significantly low heart rate of 90 beats per minute. Central cyanosis indicates that there is a lack of oxygen in the blood, which is critical in a newborn, suggesting that the baby is not effectively breathing or that there's an issue with circulation.

The heart rate is below the normal threshold for newborns, which is typically between 120 to 160 beats per minute. A heart rate of 90 beats per minute is concerning and indicates potential respiratory distress or inadequate oxygenation. In this context, initiating artificial ventilations is essential. This helps to provide oxygen directly to the lungs, improving overall oxygen saturation and addressing the central cyanosis directly.

While drying off the infant is important for body temperature regulation and can help stimulate breathing, it is not sufficient in addressing the immediate need for oxygenation in this case. Similarly, re-succion of the mouth might be needed if there is an airway obstruction, but it does not address the underlying issue. Chest compressions are indicated if the heart rate falls below 60 beats per minute and there is inadequate perfusion, but since the heart rate is still above this threshold, starting with artificial ventilation is the most appropriate initial intervention.
