Measuring changes in lung artery pressure using a non-invasive method in ICU patients

Non-Invasive Measurements of Changes in Pulmonary Artery Pressure in Intensive Care Unit Patients Using Electrical Impedance Tomography - A Feasibility Study (PAP-EIT Study)

Observational Insel Gruppe AG, University Hospital Bern · NCT06544148

This study is testing if a new non-invasive method called electrical impedance tomography can safely and accurately measure lung artery pressure in critically ill patients in the ICU.

What this trial studies

This study evaluates the feasibility of using electrical impedance tomography (EIT) to monitor changes in pulmonary artery pressure (PAP) in critically ill patients. It compares the non-invasive EIT measurements with the invasive gold-standard method of PAP measurement using a pulmonary artery catheter. The goal is to determine if EIT can provide reliable data on PAP changes without the risks associated with invasive procedures. The study focuses on intubated ICU patients who require PAP monitoring.

Who should consider this trial

Good fit: Ideal candidates are intubated patients aged 18 and older in the ICU who require monitoring of pulmonary artery pressure.

Not a fit: Patients with implanted thoracic electronic devices, open lung injuries, or certain thoracic conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a safer, non-invasive method for monitoring pulmonary artery pressure in critically ill patients.

How similar studies have performed: While this approach is innovative, similar studies using non-invasive methods for monitoring cardiovascular parameters have shown promise, suggesting potential for success.
