For measuring the properties of lung surfactant, we provide formulas for calculating the surface tension, area, and volume of captive air bubbles in aqueous media. Only measurements of bubble height (h) and diameter (d) are required. Data processing has been automated using standard video capture hardware and software, and our own image-processing and -analyzing programs. Our polynomials in h/d describe the ratios of actual bubble surface area and volume to that of a spherical bubble having the… CONTINUE READING
