Electrical Impedance Tomography in One-Lung Ventilation
Chile20 participantsStarted 2018-12-07
Plain-language summary
Mechanical ventilation can cause damage to the lung parenchyma, this is known as ventilatory induce lung injury (VILI).To avoid this damage, ventilatory strategies have been created, focused on the reduction of tidal volume, airway pressures and use of PEEP (positive end-expiratory pressure), which together are called "protective ventilation".
Although ventilation with protective parameters seems to reduce VILI in one-lung ventilation, the optimal parameters are not clear.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1This trial is using something called Electrical Impedance Tomography during one-lung ventilation — can you explain what that means for my care, and whether monitoring my lungs this way could affect how my ventilator settings are managed during surgery?
2The trial is measuring things like ventilation-perfusion ratio, pulmonary mechanics, and arterial blood gases — are these measurements just for research purposes, or could the information gathered actually be used to adjust my treatment in real time?
3The recruitment status for this trial is listed as unknown — does that mean the study is still actively enrolling patients, and is this something that's even available to me right now at our facility?
4Since this trial is listed as Phase NA, which often means it's more of an observational or device study rather than a drug trial, what level of safety data exists for using Electrical Impedance Tomography in one-lung ventilation situations like mine?
5Given that one-lung ventilation carries its own risks, how would participating in this study — with the additional monitoring it involves — compare to the standard approach my care team would normally use, and would it add any extra burden or risk to my procedure?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
