Study population: Sample Size: The sample size was calculated using the G Power statistical software with a chi-square test. Parameters used were effect size: 0.3, alpha: 0.05, and power: 0.8. Based on these conditions, the required sample size is estimated to be 88 participants. Experimental Group: Comprising 44 PMV (Prolonged Mechanical Ventilation) patients who, after extubation, are assessed by physicians to use high-flow nasal cannula oxygen therapy. Control Group: Comprising 44 PMV patients who, after extubation, are assessed by physicians to use traditional oxygen therapy.

Who may be able to join

  • Patients over 20 years old and expected to undergo extubation.

Who cannot join

  • Patients with tracheostomy who will use non-invasive or invasive ventilators immediately after extubation.

About this study

Observe the current status of prolonged mechanical ventilation (PMV) patients using high-flow nasal cannula oxygen therapy (experimental group) or traditional oxygen therapy (control group) after extubation, and compare the differences in ventilator weaning rates between the two groups.

Record the ROX index (SpO2/FiO2/RR) at 2, 6, 12, and 24 hours after extubation in PMV patients and explore whether statistical methods can predict the weaning outcome within seven days.

Use statistical methods to analyze whether comorbidities in the PMV population affect ventilator weaning rates.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. ROX index

    The oxygen concentration used before and after oxygen therapy adjustment is recorded as percent, accompanied by clinical and physiological parameter the patient's oxygen saturation (SpO₂) and respiratory rate (breaths per minute). Additionally, multiple measurements of the ROX index are performed, combining saturation (SpO₂), FiO₂, and respiratory rate to calculate and report the ROX index (SpO₂ / FiO₂ / RR).

    Measured: From enrollment to preliminary data compilation, lasting a total of 4 months.

  2. P/F ratio

    Collect the arterial oxygen partial pressure (PaO₂, mmHg) from each patient's clinical arterial blood dialysis, and compare it with the oxygen concentration (%) being used at the time. The two values are then combined to calculate the P/F ratio (PaO₂, mmHg / FiO₂, decimal).

    Measured: From enrollment to preliminary data compilation, lasting a total of 4 months.

Questions about this trial

What is this clinical trial studying?

An observational study of Post Extubation Respiratory Failure, run by Chang Gung Memorial 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 1 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: finished, as of the sponsor's last update on 27 Dec 2024. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

ROX index (time frame: From enrollment to preliminary data compilation, lasting a total of 4 months.). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06746363, which also lists 4 linked publications.

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 Dec 2024; AzTrials last refreshed its copy on 7 Nov 2026.
