This paper examines the viscous flow resistance in branching tubes as applied to simplified models of the lungs, and compares the results of Computational Fluid Dynamics (CFD) simulations for a range of conditions with measurement data. The results are in good agreement with the available measurement data for both inspiration and expiration. A detailed sensitivity analysis of the dissipation and viscous resistance in a branch then examines the ratio of the viscous resistance to that for a fully developed Poiseuille flow, Z...

BACKGROUND AND OBJECTIVE: Intrauterine growth restriction (IUGR) is associated with asthma development. We hypothesized that IUGR disrupts airway development leading to postnatal structural abnormalities of the airway that predispose to disease. This study therefore examined structural changes to the airway and lung in a rat model of maternal hypoxia-induced IUGR. METHODS: Pregnant rats were housed under hypoxic conditions (11.5% O2 ) from gestational days (GDs) 13 to 20 (pseudoglandular-canalicular stages, i...

PURPOSE: Emergent retrieval of airway foreign bodies (AFBs) in children remains a priority skill set for pediatric surgeons. In the setting of low procedural volume, simulation-based education with deliberate practice is essential to ensure trainees reach expected surgical competency. The purposes of this work were to (1) create a realistic rigid bronchoscopy for AFB retrieval simulation model and (2) to evaluate preliminary validity evidence of a novel simulator for the use of training and assessing pediatric surgical trainees' rigid bronchoscopy skills...

The factors altering the bronchodilatory response to a deep inspiration (DI) in asthma are important to decipher. In this in vitro study, we investigated the effect of changing the duration between DIs on the rate of force recovery post-DI in guinea pig bronchi. The airway smooth muscle (ASM) within the main bronchi were submitted to length oscillation that simulated tidal breathing in different contractile states during 2, 5, 10 or 30min prior to a larger length excursion that simulated a DI. The contractile states of ASM were determined by adding either methacholine or isoproterenol...

Inhalation of aerosols generated by electronic cigarettes leads to deposition of multiple chemical compounds in the human airways. In this work, an experimental method to determine regional deposition of multicomponent aerosols in an in vitro segmented, realistic human lung geometry was developed and applied to two aerosols, i.e. a monodisperse glycerol aerosol and a multicomponent aerosol. The method comprised the following steps: (1) lung cast model preparation, (2) aerosol generation and exposure, (3) extraction of deposited mass, (4) chemical quantification and (5) data processing...

BACKGROUND: Metronome guidance is a feasible and effective feedback technique to improve the quality of cardiopulmonary resuscitation (CPR). The rate of the metronome should be set between 100 to 120 ticks/minute and the speed of ventilation may have crucial effect on the quality of ventilation. We compared three different metronome rates (100, 110, 120 ticks/minute) to investigate its effect on the quality of ventilation during metronome-guided 30:2 CPR. METHODS: This is a prospective, randomized, crossover observational study using a RespiTrainer○(r)...

BACKGROUND: High-flow nasal cannula (HFNC) is supposed to provide additional PEEP compared with conventional oxygen therapy. However, the exact determinants of this PEEP effect are unclear. We investigated the factors that might affect the PEEP and compared PEEP performance among 3 HFNC devices. METHODS: Three available HFNC devices were evaluated: the AIRVO 2 device and 2 mechanical ventilators (SV300 and Monnal T75). A device consisting of a test lung (5600i) and an airway model (AMT(IE)) was used to simulate spontaneous breathing...

Otolaryngology-head and neck surgery (OTL-HNS) residents face a variety of difficult, high-stress situations, which may occur early in their training. Since these events occur infrequently, simulation-based learning has become an important part of residents' training and is already well established in fields such as anesthesia and emergency medicine. In the domain of OTL-HNS, it is gradually gaining in popularity. Crisis Resource Management (CRM), a program adapted from the aviation industry, aims to improve outcomes of crisis situations by attempting to mitigate human errors...

Emergency airway management in children is generally considered to be challenging, and endotracheal intubation requires a high level of personal skills and experience. Immobilization of the cervical spine is indicated in all patients with the risk of any cervical spine injury but significantly aggravates endotracheal intubation. The best airway device in this setting has not been established yet, although the use of videolaryngoscopes is generally promising. Seventy-five moderately experienced paramedics of the Emergency Medical Service of Poland performed endotracheal intubations in a pediatric manikin in three airway scenarios: (A) normal airway, (B) manual in-line cervical immobilization, and (C) cervical immobilization using a Patriot cervical extrication collar and using two airway techniques: (1) McGrath videolaryngoscope and (2) Macintosh blade in a randomized sequence...

BACKGROUND: Tracheomalacia (TM) is a condition of excessive tracheal collapse during exhalation. Both acquired and congenital forms of TM are believed to result from morphological changes in cartilaginous, fibrous and/or smooth muscle tissues reducing airway mechanical properties to a degree that precipitates collapse. However, neither the specific amount of mechanical property reduction nor the malacic segment lengths leading to life threatening airway collapse in TM are known. Furthermore, the specific mechanism of collapse is still debated...

CONTEXT: Management of the airway of a trauma victim is considered challenging. Various approaches have been described to achieve airway control in this setup; many of them include video-assited viewing of the larynx during intubation. ETView Single Lumen (SL) is a novice single-use endotracheal tube equiped with a video camera and a light source at its distal tip. Its use was previously described in seeral clinical and training setups. OBJECTIVE: The aim was to evaluate the efficacy of the VivaSight SL compared with classic direct laryngoscopy performed with a Macintosh blade in a manikin-simulated trauma setup presenting various degrees of airway challenge when performed by inexperienced physicians...

BACKGROUND AND AIMS: Restriction of head and neck movements prevents the alignment of the oral, pharyngeal, and laryngeal axes and increases the incidence of difficult tracheal intubation in patients with cervical spine fractures. Video laryngoscopes have gained an important role in the management of difficult intubation, especially in situations with limited head and neck movements. This study compares the success of intubation using Macintosh laryngoscope assisted Bonfils(®) fiberscope (ML-BF) with Truview(PCD) video laryngoscope (TV) in patients with simulated restricted head and neck movements...

Simulation-based education is gaining widespread acceptance in many medical specialties as an effective method to teach technical and non-technical skills. The ultimate goal of simulation is to improve health care and patient safety. Boet et al. [1] published a review on simulation-based crisis resources management (CRM) teaching, looking for evidence that it can lead to improved workplace practices and patient safety. Amongst hundreds of studies pertaining to CRM, he found only nine that were relevant, and only one that showed reduced mortality...
