What are the signs of effective ventilation in a newborn?

Effective ventilation in a newborn is primarily indicated by two key signs: visible chest rise and an increasing heart rate. When ventilation is performed correctly, you should observe the chest rising with each breath, which demonstrates that air is entering the lungs and causing adequate inflation. As the oxygenation improves with effective ventilation, the heart rate typically responds by increasing, indicating improved cardiac output and oxygen delivery to tissues.

In contrast, other signs listed do not represent effective ventilation. Decreasing respiratory rate and the presence of cyanosis are indicators that may suggest inadequate ventilation or oxygenation, as these conditions highlight respiratory distress rather than improvement. Stabilized blood pressure and decreased heart rate can indicate varying clinical situations but do not specifically reflect effective ventilation. Lastly, absence of grunting and abdominal distension might point toward a resolution of respiratory distress but do not directly assess the effectiveness of ventilation.
