Electrical Impedance Tomography (EIT) Monitoring: A Pilot Comparison to Standard of Care Assessments in Adults With Acute Lung Injury or Acute Respiratory Distress Syndrome (ARDS)
Electrical impedance tomography (EIT) monitoring has been researched as a method to
determine the spatial impedance distribution in a body cross section, but has yet to become
an established clinical tool. EIT monitoring gives a dynamic, breath-to-breath measurement
of both global and regional ventilation. Recently, there has been evidence that EIT
monitoring has great potential to become a non-invasive bedside tool for assessment of
regional lung ventilation without documented hazards. Potential applications include any
adult patients in acute respiratory failure. Data collected from this research may
contribute to improved patient safety outcomes.
PURPOSE:
The purpose of this pilot study is to examine the feasibility of using the EIT monitor in
ICU setting on patients with acute respiratory failure and to compare the EIT monitor data
to standard of care patient assessments. It is hypothesized that the EIT monitor, when
applied to adults in acute respiratory failure, will correlate with conventional standard of
care assessments for these patients.

to standard of care patient assessments. It is hypothesized that the EIT monitor, when
applied to adults in acute respiratory failure, will correlate with conventional standard of
care assessments for these patients.
METHOD:
This pilot study design will consist of a prospective, blinded evaluation of the Draeger EIT
monitor for patients with acute lung injury or acute respiratory distress syndrome.
Once a patient has met the inclusion criteria and has signed informed consent:
1. EIT electrode chest band will be applied by trained respiratory care staff.
Application includes elastic chest band with 16 electrodes.
2. EIT electrode chest band is connected to the EIT monitor which will be turned on and
will monitor and store EIT data.
3. EIT monitoring will take place for 4 to 6 hours, during dayshift (7am to 4pm)
4. Patient's may be monitored on three separate days.
No interventions, tests or modifications to the standard of care will occur to patients for
this pilot study of EIT monitoring. Clinicians guiding the care of these patients will be
blinded to the EIT data. The EIT chest band will be removed if transport of the patient is
necessary or if care is needed in the area of the chest band.
