Summary

The goal of this clinical study is to learn if a new, non-invasive monitoring method called EIT Pulse Wave can accurately measure blood flow to the lungs (pulmonary perfusion) and predict heart stroke volume (SV) in critically ill patients. It will also learn about the safety of this monitoring approach. The main questions it aims to answer are:

How well does the EIT Pulse Wave measurement of lung blood flow correlate with the SV measured by the standard method (Swan-Ganz catheter)? Can we build a reliable model to predict SV non-invasively using the EIT Pulse Wave signal? Researchers will compare the EIT Pulse Wave measurements directly with the Swan-Ganz catheter measurements to see if the new method is accurate.

Participants will:

Be critically ill adults in the ICU who are already receiving mechanical ventilation and have a Swan-Ganz catheter in place for medical reasons.

Undergo simultaneous monitoring using both the EIT device and the Swan-Ganz catheter every 30 minutes for up to 48 hours.

Have their ventilator settings adjusted to different levels as part of the study protocol while both measurements are recorded.

Interventions

DIAGNOSTIC_TEST

Synchronous Data Acquisition of EIT and Pulmonary Artery Catheter

This study is observational in design and does not impose any therapeutic interventions. The described "intervention" refers to the synchronous data acquisition process performed for research purposes. Specifically, based on routine clinical monitoring, the timing of EIT pulse wave method for pulmonary perfusion monitoring and Swan-Ganz catheter for stroke volume (SV) monitoring is precisely synchronized (to the second), and data from both are recorded for subsequent correlation and regression analysis. All monitoring methods are required for the patient's clinical diagnosis and treatment; the research activity is limited to the synchronous recording and comparison of data.
