Full 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.

Enrollment: 20 patients

Sex: All

Ages: 18 to 80 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• The tracheostomized patient requiring the convenient oxygen therapy.

Exclusion criteria

• Under 18 years;
• history of esophageal, gastric or lung surgery;
• The contraindication of using EIT (pacemaker, defibrillator, and implantable pumps).

Trial design

20 participants in 2 patient groups

The standard HFT

Description:

The high-flow oxygen was delivered via tracheostomy using a standard HFT.

The modified HFT

Description:

The high-flow oxygen was delivered via tracheostomy using a modified HFT.

Treatment:

Procedure: The modified HFT
