High-flow nasal oxygen offers benefits like precise oxygen delivery, flow-related positive end-expiratory pressure generation and improved lung function. While high-flow tracheal oxygen can also be used as an SBT method, it has reduced physiological effects due to bypassing the upper airway with a more open circuit. To enhance this limitation, investigators developed a modified high-flow tracheal oxygen tube with a smaller expiratory end diameter to increase expiratory resistance and airway pressure. This is a prospective randomized crossover study that aims to compare the physiological effects of standard and modified high-flow tracheal oxygen versus T-piece during SBT.",[25,26,27],"Critical Care","Oxygen Therapy","Mechanical Ventilation",[29,30,31],"high-flow tracheal oxygen","T piece","spontaneous breathing trial","RECRUITING","2025-03-20",{"date":35,"type":36},"2025-03-21","ACTUAL",{"date":38,"type":36},"2025-03-01",{"date":40,"type":19},"2025-12-30",{"name":42,"class":43},"Jian-Xin Zhou","OTHER",1,{"id":46,"slug":4,"hasResults":10,"nctId":47,"briefTitle":48,"officialTitle":49,"acronym":4,"eligibilityCriteria":50,"healthyVolunteers":10,"sex":15,"minAge":16,"maxAge":4,"enrollmentInfo":51,"targetDuration":4,"studyType":20,"phases":52,"briefSummary":53,"conditions":54,"keywords":56,"overallStatus":58,"whyStopped":4,"lastUpdateSubmitDate":59,"lastUpdatePostDateStruct":60,"startDateStruct":62,"completionDateStruct":64,"leadSponsor":65,"locationsCount":44},"100578857","NCT06816745","Comparison of Physiological Effects of Two Types of High-Flow Oxygen Therapy in Tracheostomized Patients","Comparison of Physiological Effects of Standard and Modified High-Flow Oxygen Therapy in Tracheostomized Patients","Inclusion Criteria:\n\nTracheostomy with stable spontaneous breathing.\n\nExclusion Criteria:\n\n1.
