Summary
Finding the optimal Positive End-Expiratory Pressure (PEEP) in infants is crucial for lung protection during mechanical ventilation. Current evidence suggests clinical observation and careful adjustment are key, with future strategies focusing on individualized pressure-volume relationships.
Area of Science:
- Neonatal Medicine
- Respiratory Physiology
- Critical Care
Background:
- Mechanical ventilation involves multiple adjustable parameters, with peak inspiratory pressure often prioritized over Positive End-Expiratory Pressure (PEEP) in infants.
- A growing understanding of PEEP's lung-protective capabilities has renewed interest in optimizing its application, termed the "best PEEP" strategy.
Purpose of the Study:
- To review the historical context and evolution of PEEP therapy.
- To examine evidence regarding appropriate PEEP levels in infants and its lung-protective value.
- To discuss current and future methods for determining the optimal "best PEEP" in neonatal respiratory support.
Main Methods:
- Literature review encompassing the history of PEEP, early concerns, infant-specific evidence, lung protection data, and methods for "best PEEP" determination.
- Analysis of studies conducted in both adult acute respiratory distress syndrome and neonatal populations.
Main Results:
- Historical data shows PEEP therapy has potential risks if not carefully managed.
- Evidence on optimal PEEP levels in infants is still evolving.
- Current approaches in neonates rely heavily on clinical judgment and cautious PEEP adjustment.
Conclusions:
- There is currently no simple substitute for experienced clinical assessment and careful PEEP titration in newborns.
- Future advancements may allow for individualized PEEP strategies based on pressure-volume relationships for enhanced lung protection.
