Zapping breathing muscles may help ventilator patients wean faster
NCT ID NCT07204821
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether electrical stimulation of the muscles used to breathe in (inspiratory) versus out (expiratory) can help patients on mechanical ventilators wean off the machine faster. The trial will include 48 adults aged 45-65 who have been on a ventilator for at least 24 hours. Researchers will measure blood gases, diaphragm movement, and ICU stay length to compare the two stimulation approaches.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Functional electrical stimulation device (Flexistem Digital electrical muscle stimulator)
- What this could lead to
- If it works, this could help patients on ventilators breathe on their own sooner, reducing ICU stays and complications.
- What could go wrong
- This is a small, early-stage trial with only 48 participants. The effect may be small or not apply to all patients. Electrical stimulation may cause discomfort or muscle fatigue.

Inclusion Criteria: * All mechanically ventilated patients will be: * Their ages range from 45 to 65 years. * Their BMI is from 25-29.9kg/m2. * Mechanically ventilated for at least 24 hours. * They all have hypoxemic respiratory failure * Glasgow coma score (GCS) ranged from 6 to 12. * Richmond Agitation-Sedation Scale score: -2 to +2 * Patients and their relatives had written informed consent. Exclusion Criteria: * Hemodynamically unstable patients. * Patients with rib fractures. * Patients with implanted pacemaker. * Obese (BMI greater than 30 kgm2). * Tachycardia. * Uncontrolled hypertension. * History of neuromuscular disease at admission. * Spinal injuries. * Inability to trigger mechanical ventilation * Pregnancy * An anticipated stay on the ventilator \<72 h at the time of study * Patients who cannot attach electrodes due to local skin damage or infection * Patients with Severe intestinal gas accumulation, structural abnormalities, and other reasons that prevent ultrasound detection of diaphragm movement. * Congenital myopathies or neuropathies, and contraindications for expiratory muscle FES (cardiac pacemaker, refractory epilepsy, recent (\< 4 weeks) abdominal surgery). * Patients with unrelieved pneumothorax and restricted diaphragm movement disorders. * Chest or diaphragm malformation
