It will also learn about the safety of this monitoring approach. The main questions it aims to answer are:\n\nHow 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.\n\nParticipants will:\n\nBe critically ill adults in the ICU who are already receiving mechanical ventilation and have a Swan-Ganz catheter in place for medical reasons.\n\nUndergo simultaneous monitoring using both the EIT device and the Swan-Ganz catheter every 30 minutes for up to 48 hours.\n\nHave their ventilator settings adjusted to different levels as part of the study protocol while both measurements are recorded.",[67,68],"Shock","Acute Respiratory Distress Syndrome",[70,68,67,71,72,73],"Critical Illness","Hemodynamic Monitoring","Electric Impedance","Pulmonary Circulation","NOT_YET_RECRUITING","2026-01-26",{"date":77,"type":78},"2026-02-04","ACTUAL",{"date":80,"type":62},"2026-02-02",{"date":82,"type":62},"2027-03-15",{"name":5,"class":6},1]
