Summary

There are two fundamentally different ways to ventilate critically ill patients: constant flow, volume-preset modes (such as volume assist-control) and pressure-preset modes (such as pressure-control and pressure-support). Critically ill patients suffer mechanical derangements of the respiratory system that raise the work of breathing. Knowledge of these mechanical properties is useful diagnostically and as a measure of response to treatment over time. It has been proposed that only constant flow, volume-preset modes are able to offer diagnostic information about the changes in the subject's lungs in terms of resistance and elastance properties. This study proposes to examine if similar information can be extracted from pressure-preset modes by comparing information from both modes of ventilation.
