Official title
Impact of High-Flow Tracheal Therapy on the Rheological Properties of Tracheobronchial Secretions in Tracheostomized Patients: A Randomized Crossover Study.
Overview
This monocentric, randomized crossover study aims to assess the impact of high-flow tracheal therapy (HFT) on the rheological properties of tracheobronchopulmonary secretions in tracheostomized patients. The primary objective is to compare the viscoelastic characteristics of secretions collected with and without HFT. Secondary objectives include evaluating the effects of HFT on dyspnea, patient comfort, and secretion appearance. The study will take place at Cliniques Universitaires Saint-Luc, with adult tracheostomized patients undergoing standard care.
Interventions
- Device High-Flow Tracheal Therapy
Device: Airvo 2 (Fisher \& Paykel Healthcare) Settings: Flow rate start at 40L/min and will be adapted according to tolerance; temperature aimed at 37°C or 34°C according to tolerance, FiO₂ set (if needed) according to SpO2 target values.
Primary outcome measures
- Critical stress (σc) [Time frame: Measured three times: at baseline, after one hour, after 4 hours]
Secondary outcome measures (6)
- Dyspnea (modified Borg scale) [Time frame: Measured two times: at baseline and after 4 hours]
- Patient Comfort (Visual Analog Scale - VAS) [Time frame: Measured two times: at baseline and after 4 hours]
- Secretion Appearance (Murray Scale) [Time frame: Measured two times: at baseline and after 4 hours]
- Viscoelastic modulus (G*) [Time frame: Measured three times: at baseline, after one hour, after 4 hours]
- Damping ratio (tan δ) [Time frame: Measured three times: at baseline, after one hour, after 4 hours]
- Critical strain (γc) [Time frame: Measured three times: at baseline, after one hour, after 4 hours]
Eligibility criteria
