  • Fundamentals of leak detection - Leybold

    The leak rate of a vessel indicates the amount of gas flow which escapes through the walls of the vessel. It must be noted, however, that the leak rate for a leak depends on the type of gas. If the gas temperature T and the molar mass M of a gas G is known, the gas mass flow can be calculated from the leak rate

  • Pleural mechanics and the pathophysiology of air leaks

    also gas exchange. The effect of a large air leak on CO 2 re-flects the diminished partial pressure of CO 2 in the periph-eral airspaces. An evacuated air leak removes CO 2, decreases the concentration of CO 2 in the alveoli, and en-hances the diffusion gradient from the blood into the al-veoli.11 The result can be a marked decline in blood CO 2
