Study summary

Modern intensive care units (ICUs) are increasingly adopting newer modes of mechanical ventilation such as adaptive pressure control (APC) modes but there are limited data available regarding risks and benefits of newer modes versus traditional ventilation modes. APC can inadvertently deliver high tidal volumes, which maybe harmful. High tidal volumes may be unrecognized by the provider, due to the complexities of ventilator algorithms and patient interactions. The objective of this aim is to identify risk factors for excess tidal volumes in patients on adaptive pressure control.
