About this study
Official title: The Effectiveness of Tidal Volume Challenge Incorporating Plethysmographic Variability Index in Predicting Fluid Responsiveness
Determine the ability of changes in Plethysmographic Variability Index during tidal volume challenge to predict fluid responsiveness
Read the detailed description
The change of Plethysmographic Variability Index after tidal volume challenge as a predictor of fluid responsiveness, confirmed with the change of SVV using Flotrac advance cardiac output monitor.
To determine whether the patient is fluid responder, Fluid challenge will be performed afterwards to confirm the patient's fluid responsiveness.
We also aim to calculate the least significant change for Plethysmographic Variability Index and Philips PPV system.

Questions about this trial
What is this clinical trial studying?
An observational study of Validation of PVI in Tidal Volume Challenge Test, run by National Taiwan University Hospital at 1 site in Taiwan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 27 Jul 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Chun-Yu Wu (0972653376, longersolo@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The predictive ability of change in Plethysmographic Variability Index after Tidal volume challenge to predict fluid responsiveness (time frame: 20 minutes). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Jul 2021; AzTrials last refreshed its copy on 27 Oct 2026.
