Respiratory Distress Syndrome: A syndrome in premature babies caused by insufficient production of pulmonary surfactant.
Alveoli: Tiny air sacs in the lungs that allow for rapid gas exchange
Pulmonary Surfactant: A mixture of lipids and proteins that decreases surface tension in the alveoli.
Law of Laplace: A law of physics stating that the pressure within a sphere is inversely proportional to its radius.
CPAP: A ventilator that provides Continuous Positive Airway Pressure (CPAP) to keep the airways open.
