Positive end-expiratory pressure during mechanical ventilation and noninvasive respiratory support in newborns and children

Area of Science:

• Pediatric Pulmonology
• Neonatology
• Critical Care Medicine

Background:

• Positive end-expiratory pressure (PEEP) is a cornerstone of respiratory support in neonates, infants, and children.
• It is utilized in both non-invasive and invasive ventilation strategies.

Purpose of the Study:

• To elucidate the multifaceted benefits of PEEP in pediatric respiratory care.
• To emphasize the importance of individualized PEEP titration for optimal outcomes.
• To highlight PEEP's role in preventing ventilator-induced lung injury and circulatory compromise.

Main Methods:

• Review of physiological effects of PEEP on respiratory mechanics and gas exchange.
• Analysis of cardiovascular impact of PEEP in critically ill pediatric patients.
• Discussion of monitoring parameters including blood gas analysis, peak inspiratory pressure (PIP), and fraction of inspired oxygen (FiO₂).

Main Results:

• PEEP enhances functional residual capacity, reduces respiratory effort, and lowers oxygen requirements.
• It allows for decreased peak inspiratory pressure (PIP) without compromising mean airway pressure.
• Cardiovascular effects are generally minimal, especially in patients without concurrent circulatory insufficiency.

Conclusions:

• Individualized PEEP titration, guided by blood gas analysis and ventilator parameters, is crucial for optimizing gas exchange and minimizing adverse effects.
• This tailored approach mitigates ventilator-induced lung injury and prevents ventilation-associated circulatory failure.
• Nasal continuous positive airway pressure (NCPAP) with appropriate PEEP is an established treatment for respiratory failure in newborns, particularly preterm infants.
