Hysteresis - means more pressure to inflate than deflate healthy lungs
The 2 factors contributing to Dynamic pressure-volume curve are - Elastic properties and surface tension
Lung follows the Law of Laplace
Surfactant
Is synthesized in Type II pneumocytes - 90% phospholipids
10% Apoproteins (A-D)
Apoprotein A and D are important for immunologic function but not critical
Apoprotein C is important but less critical
all are correct
Deficiency of Surfactant results in - pick the wrong statement
decreased lung compliance
increased work of breathing
decreased alveolar ventilation
arterial hypoxemia
respiratory alkalosis
