Brief Summary

Study Title: EIT-Guided Lung Recruitment Maneuvers in Pediatric ARDS: Effects on Ventilation Distribution and Respiratory Mechanics Study Objective: The primary goal of this clinical trial is to determine whether lung recruitment maneuvers guided by Electrical Impedance Tomography (EIT) result in a more homogeneous ventilation distribution and less injurious ventilation in children with pediatric Acute Respiratory Distress Syndrome (pARDS). The study will assess changes in intrapulmonary gas distribution and respiratory mechanics during recruitment maneuvers using both EIT and partitioned respiratory mechanics. This is a prospective cohort study involving children diagnosed with pARDS. Eligible participants will be consecutively enrolled over time and will undergo a standardized series of staircase lung recruitment maneuvers under continuous EIT monitoring. The final mechanical ventilation (MV) settings will be individualized and titrated based on the EIT-derived response to recruitment. Main Research Questions: How can lung recruitment maneuvers be performed safely in children with pARDS? How can we monitor the physiological effects of recruitment on respiratory mechanics? How does recruitment influence the distribution of ventilation within the lungs? Eligible participants will undergo a series of staircase lung recruitment maneuvers under continuous EIT monitoring. The final mechanical ventilation (MV) settings will be titrated and individualized based on the EIT-derived response to recruitment.

Outcome Measures

Primary Outcomes (1)

  • Global Inhomogeneity Index (GI)

    The Global Inhomogeneity Index (GI) is an EIT-derived quantitative measure of ventilation distribution heterogeneity across the lungs. A lower GI index indicates more homogeneous ventilation. GI will be calculated before and after the EIT-guided recruitment maneuver to assess the effect on regional ventilation distribution.

    Baseline (pre-intervention/procedure/surgery) Immediately after the intervention/procedure/surgery

Secondary Outcomes (3)

  • Differences in Tidal Impedence

    Baseline (pre-intervention/procedure/surgery) Immediately after the intervention/procedure/surgery

  • Centre of Ventilation (CoV)

    Baseline (pre-intervention/procedure/surgery) Immediately after the intervention/procedure/surgery

  • Changes in Regional Ventilation Delay (RVD) Index

    Baseline (pre-intervention/procedure/surgery) Immediately after the intervention/procedure/surgery

Other Outcomes (1)

  • Partitioned Respiratory Mechanics

    Baseline (pre-intervention/procedure/surgery) Immediately after the intervention/procedure/surgery

Study Arms (1)

EIT-Guided Recruitment

EXPERIMENTAL

This arm includes all participants undergoing a standardized staircase lung recruitment maneuver under continuous monitoring with Electrical Impedance Tomography (EIT). EIT is used to assess regional ventilation distribution and guide the titration of PEEP. Mechanical ventilation settings are adjusted based on individual EIT-derived responses. Respiratory mechanics, including transpulmonary pressure and compliance partitioning, are also recorded to evaluate physiological effects of recruitment.

Device: Electrical Impedance Tomography (EIT)-Guided Lung Recruitment

Masking Details
This is a physiological, exploratory study involving real-time monitoring of ventilation using electrical impedance tomography (EIT). Masking is not applicable because the intervention, namely EIT-guided lung recruitment, requires direct observation and real-time adjustment by clinicians based on EIT data. Therefore, no participants, care providers, investigators, or outcome assessors are masked.
