Excerpt
Implementation of assisted mechanical ventilation in acute lung injury (ALI) patients may decrease ventilator-induced lung injury by redistribution of tidal ventilation towards dependent lung regions. Up to now, tidal ventilation regional distribution has been measured by expensive and complicated methods, not readily available at the bedside. Electrical impedance tomography (EIT) is a relatively new non-invasive bedside method to monitor tidal ventilation distribution, validated in preclinical studies. We verified the feasibility of using EIT to monitor tidal ventilation regional distribution in patients undergoing assisted ventilation and we describe the effect of different pressure support levels on regional ventilation. …
