Comparing high-flow tracheal oxygen and T-piece for breathing trials

Comparison of Physiological Effects of Two Types of High-Flow Tracheal Oxygen Versus T-Piece During Spontaneous Breathing Trials in Mechanically Ventilated Patients

Not applicable Interventional Capital Medical University · NCT06816706

This study is testing whether a new type of high-flow oxygen or a standard T-piece helps patients who are coming off mechanical ventilation breathe better during trials.

What this trial studies

This study evaluates the physiological effects of two types of high-flow tracheal oxygen compared to a T-piece during spontaneous breathing trials (SBT) in patients who have been mechanically ventilated. The researchers have developed a modified high-flow tracheal oxygen tube designed to enhance expiratory resistance and airway pressure, potentially improving the effectiveness of SBTs. Participants will be randomly assigned to receive either standard or modified high-flow tracheal oxygen or a T-piece, with key physiological parameters being measured throughout the trial. The goal is to determine which method provides the best support for patients transitioning from mechanical ventilation.

Who should consider this trial

Good fit: Ideal candidates are adults who have been on mechanical ventilation for over 24 hours and are deemed ready for spontaneous breathing trials.

Not a fit: Patients who are under 18 years old, pregnant, or have significant hemodynamic or respiratory instability may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the weaning process from mechanical ventilation, leading to better patient outcomes and reduced extubation failure rates.

How similar studies have performed: Previous studies have shown promising results with high-flow nasal oxygen, but the specific approach of modified high-flow tracheal oxygen is novel and has not been extensively tested.
