Study Overview
Brief Summary
Tracheostomy is often performed in patients after or anticipated prolonged mechanical ventilation, who are usually required oxygen therapy after discontinuation of mechanical ventilation.
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.

Outcomes
Primary Outcomes
The mean end expiratory pressure.
Time Frame: the last 1 minutes of steady breathing during the standard or modified HFT.
The patients was delivering the high flow oxygen via the standard and modified HFT interface for 20 minutes.
Secondary Outcomes
- Changes in global and regional EELV(the last 1 minutes of steady breathing during the standard or modified HFT.)
