Filter by:The mechanical in-exsufflator (MI-E) is a medical device used to facilitate coughing when the patients' cough is not efficient. Studies have shown positive results in helping airway clearance in children and adults with neuromuscular disorders however there is lack of evidence in older populations. This study's aim is to evaluate the feasibility of the MI-E in older adults. The hypothesis is that the use of MI-E in older adults is feasible.
This study is to collect and summarize the cases of airway obstruction after anterior cervical operation through retrospective case analysis, to explore the risk factors of airway obstruction after anterior cervical operation, to provide the basis for the construction of evaluation system and provide reference for the nursing of postoperative complications.
The US Military is rapidly transitioning into preparing for multi-domain operations. Previous data demonstrates that the most common airway replaced in the prehospital combat setting is endotracheal intubation. Previous studies have suggested that video laryngoscopy (VL) is superior to direct laryngoscopy (DL), which is most prominently noted in the office users . However, the current durable equipment video laryngoscopes are very expensive and cost prohibitive for dispersion around the battlefield. The i-view is a novel video laryngoscope that is marketed for VL and is inexpensive and disposable. Both the durable VL and the i-view are already in use in our emergency department (ED). The investigators are also already collecting data using these devices as part of an approved protocol for an airway registry. The investigators are seeking to utilizing a clinical rotating protocol to compare these two devices in the emergency department.
The standard for treatment for people suffering from obstructive sleep apnea (OSA) syndrome involves the use of Continuous, or Automatic Positive Airway Pressure (CPAP, APAP) machines, which work by delivering air via tubing and mask to a patient at pressures of up to 20cmH2O. This increased pressure is meant to stabilize the airway to reduce obstruction events. APAP machines are generally more effective and more comfortable for patients than CPAP machines because these devices automatically adjust pressure to treat an apnea. However, this treatment is reactive and often ineffective since the necessary pressure is applied seconds after breathing has already stopped; The results of a previous study performed showed strong indications for predicting an apnea before it occurs using measurements collected by existing sensors of the CPAP and APAP machines. If apnea events can be predicted before they occur, the air pressure required to treat them could be supplied ahead of time, preventing the apnea from occurring. The hypothesis to be tested is whether obstructive sleep apnea events can be prevented, by predicting their onset ahead of time and adjusting the airway pressure accordingly.
This is a pilot study to assess the utility of the automatic stenosis index quantification using 3D Slicer software (Computer-based Quantification). We will recruit three physicians to perform a similar analysis using video images of the same bronchoscopes images (Human-based Quantification). This study relates to the latter data collection.
Light to moderate sedation is recommended during surgery with spinal anesthesia . This study is exploring which sedation drug is better, midazolam or dexmedetomidine for transurethral resection of bladder and prostate in patients with or without high risk for obstructive sleep apnea (OSA). Patients were divided in two groups regarding OSA risk, and each group received midazolam or dexmedetomidine for sedation. Investigators observed intraoperative complications of airway and factors that are disturbing surgeon(movement due to participants coughing and restlessness) because one could puncture bladder or prostate and cause perforation.
The purpose of this study is to investigate if treatment of periodontitis (gum disease) in a relatively young and healthy population can improve lung function. It is hypothesized that removing the dental biofilm reduce the source of inflammatory bacteria that can reach the lungs, and thereby reduce lung inflammation and lead to improved lung function.
This study compare the effects of Oral airway vs LMA in preventing anesthesia-induced partial airway obstruction, in an attempt to lessen MRI motion artifacts, which would result in improvements in image quality.
Narrow-Band Imaging (NBI) is useful to better demarcate the superficial extent of central type of lung cancer, but its sensitivity and specificity in clinical practice were little studied. This study aimed to investigate the diagnostic effects of NBI in suspected patients with central lung cancer and its application in staging diagnosis of central lung cancer.
The purpose of this investigation is to obtain more information on the efficacy and safety of respiratory training methods with WellO2 in patients with asthma and COPD. Such a training may offer an additional, non-pharmacological way for treatment and therapy of asthma and COPD.
