What might rapidly increasing oxygen requirements indicate in an infant?

Rapidly increasing oxygen requirements in an infant are concerning and often indicate that the infant is facing worsening respiratory or cardiac function. When an infant's body demands more oxygen, it can be a sign that the lungs are not effectively exchanging gases or that the heart is struggling to pump adequately. This can occur due to several underlying conditions, such as respiratory distress syndrome, congenital heart defects, or infections.

Recognizing this early on is crucial, as it allows for timely interventions that can prevent further deterioration of the infant's condition. Therefore, the significant need for increased oxygen can serve as a warning sign of impending respiratory or cardiac failure, necessitating immediate assessment and potential treatment.
