Filter by:This study is to evaluate the efficacy of a new therapy (Automatic Expiratory Positive Airway Pressure with intelligent Volume Assured Pressure Support (AutoEPAP iVAPS)) designed to treat respiratory insufficiency, respiratory failure and/or nocturnal hypoventilation with upper airway obstruction. The study will be performed in two phases: In a sleep unit and in the home environment. The new therapy will be compared against two existing ventilator therapies: "Spontaneous Timed (ST) mode" and "Intelligent Volume Assured Pressure Support (iVAPS)".
The purpose of this study is to evaluate the efficacy and safety of four interventional pulmonology techniques for the treatment of malignant central airway stricture. The four techniques are： - cryotherapy - argon plasma coagulation - stent - snare
The use of laryngeal mask airway or i-gel to manage airway may improve success rates, especially in difficult situations more than tracheal intubation.
Cryotherapy has a long history of safe use in various medical procedures. RejuvenAir System radial spray cryotherapy is a novel procedure being developed as a treatment for conditions associated with abnormal bronchial function, such as chronic bronchitis. The development of appropriate reliable equipment, definition of therapeutic parameters, and an understanding of the tissue effects of treatment have been established through animal studies. This clinical study is being undertaken to assess the feasibility and safety of the application of a radial metered dose spray cryotherapy in the human airway and to evaluate the treatment depth in human airways. The study design is prospective, open label, single arm multi-center study that will consist of up to 15 subjects at up to 3 enrolling sites in Ireland, UK and The Netherlands RejuvenAir System treatment will be performed during preoperative bronchoscopy 0 to 60 days prior to prescheduled lung resection in Subjects requiring lobectomy or pneumonectomy for removal of peripheral tumors. Treatment will be limited to areas of the bronchi within the lobe that will be removed, distal to the anticipated margin of resection. Treatment should be at least 1 cm from the bronchial resection margins and away from the tumor bed. Treated airways will be inspected via bronchoscopy at the time of thoracotomy, and examined histologically following surgical resection. Subject participation will be from 1 to 60 days and enrollment is anticipated to take 4-5 months.Total study duration is expected to last approximately 10 months.
Assess the safety and feasibility of local oncological drug delivery into the bronchial wall after recanalization of subjects with malignant airway obstruction. Safety and feasibility (technical success) will be assessed. This localized delivery is intended as an adjunct therapy and all subjects will receive standard of care oncology therapy as determined by their treating physicians.
Pilot Study of the Aerin Medical Wand used for Improvement in Nasal Breathing
The purpose of this study is to prospectively assess the efficacy and safety of spray cryotherapy ablation with the truFreeze System in conjunction with mechanical dilation or debridement for the treatment of clinically significant obstructions of the central airways. The primary effectiveness endpoint is the proportion of subjects with a minimum of 25% improvement in luminal patency following SCT treatment and mechanical intervention 30 days (+/- 5 days) following treatment. Additionally, a primary clinical safety endpoint is the reporting of all adverse events.
The primary goal of this study is to determine the effectiveness and safety of delivering continuous negative external pressure (cNEP) to the upper airway as a means of preventing episodes of respiratory impairment (RI) such as hypoxemia, apnea and hypoventilation associated with the use of intravenous sedation in elective colonoscopy in adult patients.
The goal of this study is to collect raw waveform data for two separate noninvasive methods, both of which may be useful for the assessment of upper airway obstruction.
Total arytenoidectomy is claimed to increase risk of aspiration and cause more voice loss than other operations performed for bilateral vocal fold paralysis (BVFP). However, objective evidence for such conclusion is lacking. There is no study comparing swallowing and voice after total and partial arytenoidectomy.
