Bedside EIT-guided respiratory physiotherapy for adults on long-term ventilators

Official title: Electrical Impedance Tomography-Guided Respiratory Physiotherapy for Liberation From Prolonged Mechanical Ventilation: A Multicenter Randomized Controlled Trial

Run by Capital Medical University · NCT07372794 · Data updated 2026-11-12

This trial will test whether using bedside electrical impedance tomography to guide respiratory physiotherapy helps adults who have been on a ventilator for 21 days or more get more days off the ventilator within the first 28 days.

Is this trial a fit for you?

Likely a good fit

Adults aged 18 or older who have been on invasive mechanical ventilation for at least 21 consecutive days, are clinically stable for physiotherapy, and are expected to remain ventilated for at least 48 hours after enrollment are ideal candidates.

Probably not a fit

Patients with contraindications to EIT, severe hemodynamic instability or refractory hypoxemia, unstable fractures or other limits to mobilization/positioning, pregnancy, or an expected death within 48 hours are unlikely to benefit or be eligible.

What this trial studies

This multicenter randomized controlled trial will randomize adults who have received invasive mechanical ventilation for at least 21 consecutive days to either respiratory physiotherapy guided by real-time electrical impedance tomography (EIT) or to standardized conventional respiratory physiotherapy, with both groups receiving standard ICU care. Respiratory physiotherapy includes airway clearance, chest physiotherapy, breathing pattern optimization, and therapeutic positioning delivered with comparable frequency and duration between groups. In the EIT-guided arm, clinicians will use predefined ventilation distribution indicators on real-time EIT images to individualize physiotherapy maneuvers during each session. The primary outcome is ventilator-free days at day 28, with secondary outcomes including successful liberation from invasive ventilation and diaphragm ultrasound measures.

Why it matters

Potential benefit: If successful, this approach could increase days off the ventilator and shorten the duration of invasive ventilation for patients with prolonged mechanical ventilation.

How similar studies have gone: Small physiologic studies and pilot trials suggest EIT can help tailor ventilation and improve regional lung ventilation, but large randomized trials in prolonged mechanical ventilation are limited and the approach remains promising but not yet proven.
