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

Insel Gruppe AG, University Hospital Bern

Status: Enrolling

Conditions: Pulmonary Artery Hypertension

Treatments: Device: Electrical impedance tomography

Study type: Observational

Funder types: Other; Industry

Identifiers

NCT06544148

2024-00435

Details and patient eligibility

About

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).

Enrollment: 28 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Age ≥ 18-year-old.
• Intubated patients in the ICU with clinical decision to monitor PAP and cardiac output using a PAC.

Exclusion criteria

• 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)
