If a newborn does not respond to the initial steps of resuscitation, which parameters are critical for further intervention?

The correct choice emphasizes the significance of respiratory effort, pulse rate, and color in determining the need for further intervention in a newborn who is not responding to initial resuscitation steps.

Respiratory effort is crucial as it helps assess whether the newborn is adequately breathing or if there is a need for assisted ventilation. The absence of effective breathing could indicate a deteriorating condition requiring immediate intervention.

The pulse rate is an essential indicator of cardiovascular status. A normal pulse rate is vital for effective circulation and oxygen delivery throughout the body; a low pulse rate may signal significant distress and the need for advanced resuscitation measures.

Color serves as a visual indicator of oxygenation and perfusion. A newborn with poor coloration, such as cyanosis, suggests inadequate oxygenation, necessitating further intervention to improve respiratory function and overall oxygen delivery.

These parameters together provide a comprehensive assessment of the newborn's health, guiding healthcare providers in making critical decisions moving forward.
