Non-Invasive Measurements of Changes in Pulmonary Artery Pressure in Intensive Care Unit Patients Using Electrical Impedance Tomography - A Feasibility Study
Non-Invasive Measurements of Changes in Pulmonary Artery Pressure in Intensive Care Unit Patients Using Electrical Impedance Tomography - A Feasibility Study (PAP-EIT Study)
Insel Gruppe AG, University Hospital Bern
28 participants

OBSERVATIONAL
Conditions
Summary
To assess whether changes in electrical impedance - measured using an electrical impedance tomography (EIT) chest belt - can be used to derive changes in pulmonary artery pressure (PAP) in critically ill patients when compared to invasive gold-standard PAP measured using pulmonary artery catheter (PAC).
Eligibility
Inclusion Criteria2
- Age ≥ 18-year-old.
- Intubated patients in the ICU with clinical decision to monitor PAP and cardiac output using a PAC.
Exclusion Criteria6
- Patients with implanted or external thoracic electronic devices (e.g., pacemaker) or thoracic metal implants.
- Known pregnancy or lactating patients.
- Open lung injuries or pneumothorax.
- Open wounds, drainages, burns or rashes of the upper thorax.
- Estimated thoracic perimeter smaller than 66 cm or larger than 134 cm.
- Known allergies to wound dressings or adhesives (e.g., gel electrodes)
Interventions
In addition to routine critical care with a pulmonary artery catheter already in place (PAC), an electrical impedance tomography (EIT) belt will be placed in patients enrolled in this study. Data will be analyzed offline and clinical trajectory and/or decisions will not be impacted by this additional monitoring. EIT is a non-invasive, safe, and radiation-free medical imaging modality.
