About this study
Official title: Physiological Effects of High-Flow Tracheal Oxygen Via An Modified Interface in Tracheostomized Patients
Tracheostomy is often performed in patients after or anticipated prolonged mechanical ventilation, who are usually required oxygen therapy after discontinuation of mechanical ventilation.
Read the detailed description
Tracheostomy is often performed in patients after or anticipated prolonged mechanical ventilation, who are usually required oxygen therapy after discontinuation of mechanical ventilation.The high-flow tracheal (HFT) oxygen therapy in tracheostomized patients has been shown that can improve oxygenation,but can not induce positive end-expiratory pressure and elevation of end-expiratory lung volume. A modified HFT system by increasing expiratory resistance might induce PEEP and consequently elevate EELV.
- Conditions
- Tracheostomy
- Being tested
- The modified HFT
- Keywords
- high flow tracheal oxygen, modified interface
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
The modified HFTProcedure or surgery
The HFT was modified by increasing the expiratory resistance.
| Study group | Role | What they receive |
|---|---|---|
| The standard HFT | The high-flow oxygen was delivered via tracheostomy using a standard HFT. | |
| The modified HFT | The high-flow oxygen was delivered via tracheostomy using a modified HFT. Receives: Procedure: The modified HFT |
What is being measured
The primary outcome is the main question the study is designed to answer.
The mean end expiratory pressure.
The patients was delivering the high flow oxygen via the standard and modified HFT interface for 20 minutes.
Measured: the last 1 minutes of steady breathing during the standard or modified HFT.
Secondary outcomes (1)
Changes in global and regional EELV
The Electrical impedance tomography (EIT) was applied in monitoring the change of EELV at the bedside.
Measured: the last 1 minutes of steady breathing during the standard or modified HFT.

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?
The mean end expiratory pressure. (time frame: the last 1 minutes of steady breathing during the standard or modified HFT.). 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 12 Feb 2018; AzTrials last refreshed its copy on 6 Nov 2026.
