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

Last updated: November 12, 2024
Sponsor: Insel Gruppe AG, University Hospital Bern
Overall Status: Active - Recruiting

Phase

N/A

Condition

Pulmonary Arterial Hypertension

Treatment

Electrical impedance tomography

Clinical Study ID

NCT06544148
2024-00435
  • Ages > 18
  • All Genders

Study 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 Criteria

Inclusion

Inclusion criteria:

  • Age ≥ 18-year-old.

  • Intubated patients in the ICU with clinical decision to monitor PAP and cardiacoutput using a PAC.

Exclusion

Exclusion criteria:

  • Patients with implanted or external thoracic electronic devices (e.g., pacemaker) orthoracic 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)
