Table 5 Values of the two parameters (high pressure triggering sensitivity η h and pressure rise duration τ pr) maximizing the synchronizability ε according to the pulmonary model considered. These values were obtained from the tests performed under the protocol we defined and do not imply that a better combination of settings can not be found. The pressure release triggering sensitivity η l is also reported
