WebAug 1, 2005 · The pulsating bubble surfactometer (PBS) is often used for in vitro characterization of exogenous lung surfactant replacements and lung surfactant components. However, the commercially available PBS is not able to dynamically track bubble size and shape.
WebApr 10, 2024 · Beractant is used as an intratracheal suspension. It is administered as 100 mg per kg (kilogram), which is 4 mL per kg of birth weight in four divided doses. It should be given within 15 minutes after birth. Repeated doses are administered if the neonate has radiographically confirmed respiratory distress syndrome. WebINTRODUCTION A pulmonary surfactant (PS) is a lipid-protein complex that covers the entire air-water surface of the lung as a thin film (1,2). It consists of 80% phospholipids, 5–10% neutral lipids (mainly cholesterol), and 5–10% surfactant-associ- …
