Respiratory distress is defined as an abnormal physiologic condition identified by increased work of breathing; respiratory failure is defined as the period when the child exhausts his energy reserves, can no longer maintain oxygenation and ventilation, and begins to decompensate; and respiratory arrest is defined as the absence of effective breathing.
