Aspects on Oxygenation in Preterm Infants before, Immediately after Birth, and Beyond

Area of Science:

• Neonatal Medicine
• Pediatric Pulmonology
• Biomedical Engineering

Background:

• Oxygen is essential for life, but both hypoxia and hyperoxia can be detrimental, leading to severe health consequences.
• Preterm infants possess immature physiological systems, compromising their ability to regulate oxygen balance effectively.
• The critical window for oxygen management extends from fetal development through neonatal care and post-discharge monitoring.

Purpose of the Study:

• To review the complexities and challenges in maintaining optimal oxygenation in preterm infants.
• To highlight the risks associated with both insufficient and excessive oxygen exposure in neonates.
• To identify limitations in current technologies and services for precise oxygen monitoring and control.

Main Methods:

• Literature review of existing evidence on oxygen management in preterm infants.
• Analysis of physiological challenges in oxygen homeostasis during the neonatal period.
• Examination of technological and clinical service gaps in intensive care settings.

Main Results:

• Preterm infants require careful oxygen supplementation to prevent hypoxia due to underdeveloped lungs.
• Immature antioxidant defenses in preterm infants increase susceptibility to hyperoxia-related injury.
• Significant challenges exist in achieving safe and effective oxygen therapy for newborns with current medical capabilities.

Conclusions:

• Striking a balance in oxygen therapy is paramount, especially during the transition to extrauterine life.
• Advanced monitoring and responsive interventions are needed to mitigate risks of hypoxia and hyperoxia in preterm infants.
• Overcoming current limitations is essential for improving the long-term outcomes of preterm infants receiving oxygen therapy.
