air leak syndrome
Collection of conditions where air escapes from the alveoli into abnormal spaces within the thorax.
Full Definition
Air leak syndrome encompasses a group of conditions characterized by abnormal accumulation of air outside the alveolar spaces, including pneumothorax, pneumomediastinum, pneumopericardium, and pulmonary interstitial emphysema. These complications are particularly common in premature infants receiving mechanical ventilation due to surfactant deficiency and increased ventilator pressures. Air leaks result from alveolar rupture caused by overdistention, with air subsequently tracking along tissue planes. The severity ranges from asymptomatic incidental findings to life-threatening emergencies requiring immediate decompression. Risk factors include prematurity, respiratory distress syndrome, and aggressive ventilation strategies.
Usage
Usage note: Umbrella term for multiple air leak complications; specify the particular type when documenting clinical findings.
