In the acute phases of respiratory failure, assist-control modes assure adequate support. The choice of pressure targeting versus flow-volume targeting largely depends on clinician experience with the various modes, as clinical trials showing outcome benefits to either approach do not exist. The usual I/E ratio is 1 2 to 1 4, with the flow graphics being checked to ensure adequate expiratory time, to avoid air trapping. 

Equation (6-1) shows that the reaction rate can be obtained directly in a CSTR if the fractional conversion jca is measured, and if the molar feed rate Fao and the reactor volume V (or the catalyst weight W) are known. However, it is good practice to measure the complete composition of the effluent stream, even though the concentration of every species can be calculated from xa- Measuring every concentration provides a check on the quality of the data, and allows the Law of definite proportions to be used to ensure that only one reaction takes place at the conditions of the experiment. The temperature of the reactor must also be measured and carefully controlled.
