Outcome Measures

Primary Outcomes (2)

  • Regional ventilation and perfusion distribution ratio

    Percentage of relative ventilation in each Region Of Interest (ROI) in each of the studied positions

    60 minutes

  • Global mechanical compliance and regional impedance compliance

    Global mechanical compliance and regional impedance compliance (CZ) for each ROI in each of the studied positions.

    60 minutes

Secondary Outcomes (4)

  • Assessment of lung mechanics.

    60 minutes

  • Assessment of ventilation/perfusion lung distribution.

    60 minutes

  • Assesment of changes in ventilation/perfusion in prone position.

    60 minutes

  • Assessment of the effects of postural therapy in cases of predominantly unilateral lung pathology

    60 minutes

Sampling MethodNon-Probability Sample
Study Population

Critically ill patients admitted in the ICU of La Princesa University Hospital, Madrid, Spain.

You may qualify if:

  • Patients undergoing IMV under sedation, in a controlled ventilatory modality in passive conditions (i.e. without any spontaneous inspiratory efforts by the patient).
  • Signature of the informed consent by family member or legal representative.

You may not qualify if:

  • Presence of any clinical contraindication for postural therapy, including patient haemodynamic instability, traumatism, pathology or any other cause.
  • Contraindication for the placement of the EIT electrode belt due to unstable spinal cord injury or other skin injuries or wounds in the thoracic region (surgical, traumatic, etc.)
  • Assisted ventilatory modes in a non-passive breathing patient.
  • Hypernatremia
  • Patients with pacemakers or implantable automatic defibrillators (IAD).
