What is the first sign of effective resuscitation in a newborn?

The initial sign of effective resuscitation in a newborn is reflected in an increased heart rate. When resuscitation efforts are successful, one of the primary physiological responses is the restoration of a normal heart rate, which is crucial for adequate perfusion and oxygen delivery to vital organs.

Following birth, a newborn should have a heart rate of at least 100 beats per minute. If resuscitation maneuvers, such as positive pressure ventilation or chest compressions, are effective, there will be a prompt increase in the heart rate. Monitoring this vital sign is essential, as it can indicate the overall responsiveness of the newborn to resuscitative efforts.

While improved skin color, effective breathing, and increased blood pressure are also important indicators of recovery, they typically follow the restoration of a normal heart rate. For instance, improved breathing may occur as the heart rate increases, and the skin color typically brightens once adequate circulation is established. Increased blood pressure can also improve as a result of the heart rate returning to normal, but the heart rate is a more immediate and direct indicator of successful resuscitation efforts.
