Effects of two ventilator-weaning methods on lung volume and ventilation distribution by electrical impedance tomography in post-cardiac surgery patients: a prospective cohort study
The successful weaning patients had a higher reduction of EELV<sub>loss PSV</sub> and a lower reduction of EELV<sub>loss T-piece</sub>. In the weaning failure patients, the paradox of lower EELV<sub>loss PSV</sub> that was accompanied by a high RR and low VT might be associated with air trapping. Attention should be paid to using EELV<sub>loss PSV</sub> to identify weaning failure.
