WebMar 27, 2024 · Proper management of mechanical ventilation also requires an understanding of lung pressures and lung compliance. Normal lung compliance is around 100 ml/cmH20. This means that in a normal lung the administration of 500 ml of air via positive pressure ventilation will increase the alveolar pressure by 5 cm H2O. WebMar 16, 2024 · Pulmonary alveolar proteinosis (PAP) is a rare disease in which proteins accumulate in the alveoli. It is most often an autoimmune condition, meaning the immune system attacks healthy cells. PAP usually occurs in adults ages 20 to 50. It can also be a condition that is present at birth (congenital condition).
