Although baseline oxygenation was high, Pa(O2) and dynamic compliance further increased during the RM. Despite the use of high PIP and PEEP and a high tidal volume, limited cardiovascular compromise was detected. A PEEP titration-RM may be used to improve oxygenation in anesthetized ponies. During stable hemodynamic conditions, PEEP titration-RM can be performed with acceptable adverse cardiovascular effects.

This paper examines whether individuals who become either entrepreneurs or employees follow systematically different educational paths to a given educational level. Following Lazear's jack-of-all-trades theory, we expect that entrepreneurs aim at a balanced set of different skills-that is, they combine academic and vocational skills-while employees specialize in one skill. This means that entrepreneurs follow educational paths that combine different types of education, while employees follow same-type paths while climbing up the educational ladder. We use the Swiss Labor Force Survey to test our hypothesis. Our empirical findings are in line with Lazear's theory and indicate that individuals who change between different types of education and acquire a more balanced set of skills are more likely to become entrepreneurs. Thus, the permeability of a country-specific educational system is one crucial determinant of entrepreneurship.
