Outcome Measures

Primary Outcomes (4)

  • Validation of the measurement of absolute values of effective lung volume

    To validate the measurement of absolute values of effective lung volume by the capnodynamic method previously described, as an estimate of end-expiratory lung volume. For this purpose the capnodynamic method will be compared with gold standard reference method for measuring lung volumes, the computerized tomography scan (CTscan).

    1 day

  • Analyze to which pulmonary compartments does effective lung volume most closely correlate

    Tomographic aeration level according to the density distribution analysis (non aerated, poorly aerated, normally and hyper aerated) does effective lung volume most closely correlate; taking into account that the CTscan measures an anatomic rather than a functional lung volume.

    1 day

  • Improvement of capnodynamic ELV measurement

    To determine the effects of lung collapse on the accuracy and precision of the capnodynamic ELV measurement.

    1 day

  • Trending ability of the capnodynamic end-expiratory lung volume method

    Breath by breath changes in EELVCO2 will be compared with breath by breath changes in lung aeration measured by electrical impedance tomography.

Sampling MethodNon-Probability Sample
Study Population

Critically ill patients undergoing mechanical ventilation

You may qualify if:

  • All patients on mechanical ventilation in passive breathing conditions in which a thoracic CTscan has been indicated for medical reasons and those with an EIT and a continuous cardiac monitoring
  • Informed consent

You may not qualify if:

  • Hemodynamic instability
  • Presence of barotrauma/ pneumothorax
  • Presence of bronchopleural fistulas
  • Thorax alterations that preclude the positioning of the EIT electrode belt (usually at the IV intercostal space).
