No results posted yet for this study

Summary

In a population of ARDS patients, we explore the influence of different PEEP levels on regional ventilation distribution, ventilation homogeneity, and the center of ventilation, optimal PEEP and lung recruitment potential as well as the extent of lung collapse and overdistension as detected by 3D-EIT.

Conditions

Interventions

PROCEDURE

lung recruitment potential assessed by 3D EIT

Patients were ventilated based on the ARDS-Net suggestions. The patients were kept at supine position. The lung recruitment potential assessed by 3D EIT was as follows: 1. All patients were under pressure control mode (driving pressure 12-15 cmH2O with a tidal volume of 6-8 ml/kg predicted body weight, respiration rate12-15 bpm). 2. PEEP was switched to a zero end-expiratory pressure (ZEEP) for 10 min, and FiO2 was titrated to obtain peripheral oxygen saturation (SpO2 ) \> 90%. 3. PEEP was stepwise increase from 0 to 15 cmH2O PEEP in steps of 5cm H2O every 3min.And 3D EIT was used to assess lung recruitment potential.

PROCEDURE

PEEP titration by 3D eit

Patients were ventilated based on the ARDS-Net suggestions. The patients were kept at supine position. The PEEP titriatino by 3D EIT fwas as follows: 1. All patients were under pressure control mode (driving pressure 12-15 cmH2O with a tidal volume of 6-8 ml/kg predicted body weight, respiration rate12-15 bpm). 2. RM: PEEP was switched to a 21cmH2O for 2min, and FiO2 was titrated to obtain peripheral oxygen saturation (SpO2 ) ≥90%. 3. PEEP was stepwise decrease from 21 to 0 cmH2O PEEP in steps of 3cm H2O every 2min. 4. 3D EIT was used to monitor regional ventilation distribution during PEEP titration.
