What are the signs of effective ventilation in a newborn?

Effective ventilation in a newborn is characterized by several key indicators that reflect proper oxygenation and breathing patterns. Notably, an increasing heart rate signifies that the newborn is responding positively to the ventilation, as effective breathing helps improve oxygen delivery to the body's tissues and organs. Additionally, visible chest rise during ventilation is crucial because it confirms that air is entering the lungs and causing the chest to expand, indicating successful inflation. Adequate oxygenation is typically assessed through the use of pulse oximetry, which measures the oxygen saturation in the blood. When these signs—an increasing heart rate, chest rise, and adequate oxygenation—are present, they collectively demonstrate that the newborn is receiving the vital assistance needed for effective airway management and overall respiratory function.
