It plays an important role in keeping the lungs open, enabling all areas of the lungs to undergo gas exchange.
One of these settings is called PEEP, which is a continuous distending pressure applied throughout the respiratory cycle.
Gas exchange is achieved by several ventilator settings that help cycle heated, humidified and (sometimes) oxygen-enriched air in and out of the lungs. While this therapy can improve pulmonary gas exchange and lead to benefits, it may simultaneously injure the lungs and cause harms. Conventional mechanical ventilation (the use of a breathing machine) following endotracheal intubation (placement of a breathing tube in the windpipe) is a commonly used therapy for both complications. RDS and BPD are complications of premature babies that describe early (RDS) and late (BPD) respiratory failure as a result of preterm birth. Review question: how do different positive end-expiratory pressure (PEEP) levels, or different approaches for selecting PEEP levels, compare on their effects in preterm infants with respiratory distress syndrome (RDS) or bronchopulmonary dysplasia (BPD)?īackground: infants born preterm (before 37 weeks' gestational age) often have respiratory failure and require medical support to achieve adequate pulmonary gas exchange (removing carbon dioxide from the blood and replenishing it with oxygen).
