Filter by:Prospective, observational, study that will examine if a sited supraglottic airway (the igel) will increase the accuracy of identifying the cricothyroid membrane in female patients. Consented patients that meet inclusion criteria are assessed by clinicians under general anaesthesia with and without a supraglottic airway in situ. The accuracy of CTM identification by palpation will be evaluated using ultrasound.
In a prospective, observational study the investigators compared resistance values measured using the airway perturbation device (APD) to impulse oscillometry and spirometry. The investigators also created reference equations for normal APD resistance ranges using the data from clinically normal volunteers.
The purpose of this study is to compare the effect of mandibular advancement bite block to standard bite block for prevention of hypoxemia, intervention events and adverse effects during endoscopic examinations.
Evaluation of the Aerin Medical Device used for the treatment of nasal obstruction.
Patients with chronic respiratory failure such as those associated with Chronic Obstructive Pulmonary Disease (COPD), Obesity Hypoventilation Syndrome (OHS), Obstructive Sleep Apnea (OSA) or Neuromuscular Disease (NMD) are increasingly managed with domiciliary non-invasive positive pressure ventilation (NIPPV). The aim of this study is to now compare the Automatic Expiratory Positive Airway Pressure (AutoEPAP) algorithm with a fixed manual EPAP in iVAPS mode on an Astral mixed mode ventilator. It is proposed that the automatic settings of AutoEPAP will be as effective at managing respiratory failure and upper airway obstruction (UAO) as manual EPAP on the Astral device. Specifically demonstrating that the AutoEPAP function is as effective at treating UAO as manual EPAP.
Patients with obstructive sleep apnea (OSA) could have several anatomical causes of obstruction. A sleep endoscopy study is a technique to help determine the anatomical cause of OSA. This study will be using standard of care practice and infuse dexmedetomidine (DEX) to induce sleep. The goals of the study are to (1) confirm airway obstruction with endoscopic view and correlate that with Acoustic Respiratory Rate (RRa) signal at the moment of airway obstruction, and (2) characterize the EEG signals when subjects are under DEX sedation alone.
Literature shows that anaesthetists have a low success-rate when trying to access the airway percutaneously in case of failed ventilation and intubation. The study will investigate anaesthetists ability to locate the trachea and the thyroid cartilage and the cricoid cartilage in patients, using different methods including application of ultrasonography.
Rationale: Spray cryotherapy (SCT) using liquid nitrogen has been safely and effectively used in the esophagus, airways and pleura. Treatment with SCT for central airway stenosis may provide an effective, and more durable and perhaps safer alternative to the current therapeutic modalities. Objectives: 1. To investigate the feasibility of using Spray cryotherapy (SCT) for the treatment of malignant and benign central airway disease. 2. To investigate the safety of using Spray cryotherapy (SCT) for the treatment of malignant and benign central airway disease. 3. To investigate the efficacy of using Spray cryotherapy (SCT) for the treatment of malignant and benign central airway disease. Study design: This study will be a prospective, single arm, open label intervention study performed at the University Medical Center Groningen, The Netherlands Study population: The study population exists of 25 patients with malignant or benign central airway disease. Patients in which current treatment options are regarded to be suboptimal can be included in the study. Intervention: TruFreeze Spray CryoTherapy Main study parameter: Feasibility is defined as being able to apply the SCT as planned in one, or more bronchoscopies according to the instructions for use (IFU). Secondary study parameters: Safety will be assessed by capturing all adverse events (AEs) that occur 1) during the SCT procedure, and 2) all AEs that occur until hospital discharge. Efficacy will be measured using 1) patient reported outcomes (questionnaires), 2) percentage improvement in airway stenosis, 3) durability of treatment effect, 4) need to re-intervene with other therapies because of treatment failure. Nature and extent of the burden, risks and benefit associated with participation. Patients that will be recruited and participate in this prospective clinical trial have a severe central airway disease which is highly symptomatic for which current available therapies are either very difficult to perform, are hazardous, have no real benefit, or just simply not available yet. The current treatment risks of this patient group are high, especially in the patients where the airway patency is at risk. The main additional risk associated with the use of SCT is the occurrence of a pneumothorax. Patients participating will adhere to their current medical care, with the one addition of a voluntary follow-up bronchoscopy after SCT.
In preschool aged children, the most suitable techniques to assess airway obstruction is debit interruption technic (Rint) and plethysmographic measure of specific airway resistance (sRaw). Even if Rint is easily and routinely performed, it also includes a component of lung tissue and chest wall resistance as well as respiratory tissue viscoelasticity. sRaw seems to be better for discriminating airway obstruction. These two techniques will be compared in terms of concordance in the diagnosis of pulmonary obstruction and bronchodilator response.
The ELISABET STUDY is across sectional Survey on a representative sample of two urban area conduct on a representative sample. The main objective of the project is to compare the prevalence of the obstructive ventilatory disorders (OVD) in the Urban Community of Dunkirk touched by the industrial pollution in relation to the one recovered in the Urban Community of Lille (CUDL) less industrialized.
