Noninvasive ventilation (NIV) frequently involves the development of facial pressure ulcers (FPU). Its prevention considers the empirical use of protective patches between skin and mask, in order to reduce the pressure exerted by it. OBJECTIVES: To evaluate the effect of protective patches on the pressure exerted by the facial mask, and its impact on the programmed ventilatory parameters. METHOD: Bilevel NIV simulated model using full face mask in phantom with a physiological airway (ALS PRO +) in supine position...

INTRODUCTION: Dyspnea due to bilateral vocal cord palsy after total thyroidectomy (BVCPATT) is a life-threatening complication; nevertheless, we try to avoid tracheotomy. METHODS: Using normalized glottal area (NGA), we retrospectively studied 14 patients with BVCPATT. Nine patients without dyspnea were treated conservatively, while five with dyspnea received immediate bilevel positive air-way pressure (BiPAP) treatment. Both right and left recurrent nerves were grossly intact during surgery...

BACKGROUND: Non-invasive ventilation (NIV) significantly changed the management of respiratory distress syndrome (RDS) in preterm infants. Further perspectives for neonatologists regard the assessment of different NIV strategies in terms of availability, effectiveness, and failure. OBJECTIVE: The aim of the present study is to evaluate the effectiveness of three different NIV strategies: nasal continuous positive airway pressure (N-CPAP), nasal synchronized intermittent positive pressure ventilation (N-SIPPV), and nasal bilevel-CPAP (BiPAP), as first intention treatment for RDS in very low birth-weight infants (VLBW)...

BACKGROUND: Amyotrophic lateral sclerosis is a fatal neuromuscular disorder characterized by progressive death of the upper and lower motor neurons in the central nervous system. Patients with this disease die mostly as a result of respiratory failure; however, owing to prolonged survival through assisted ventilation, cardiovascular causes are increasingly responsible for mortality. We report what is to the best of our knowledge the first case of type 2 Brugada syndrome causing ventricular tachyarrhythmia and cardiac arrest in a patient with upper limb onset amyotrophic lateral sclerosis...

Although non-invasive ventilation (NIV) has been used since the 1960's in the polio epidemic, the development of modern bilevel PAP devices did not become a reality until the 1990's. Over the last 25 years bilevel PAP technology options have exponentially increased. The number of patients receiving this treatment both in the acute setting as well as at home is steadily growing. However, a knowledge gap exists in the way these device settings are adjusted to achieve synchrony and match patient's unique respiratory failure physiology...

BACKGROUND: A breath-synchronized nebulization option that could potentially improve drug delivery during noninvasive positive pressure ventilation (NIPPV) is currently not available on single-limb circuit bilevel ventilators. The aim of this study was to compare urinary excretion of amikacin following aerosol delivery with a vibrating mesh nebulizer coupled to a single-limb circuit bilevel ventilator, using conventional continuous (Conti-Neb) and experimental inspiratory synchronized (Inspi-Neb) nebulization modes...

We report a case of an elderly male with predominant obstructive sleep apnea and who developed or complex sleep apnea (CxSA) at the start of continuous positive airway pressure (CPAP) titration. This CxSA was more prominent in supine position, and he was not settling with either CPAP/bilevel positive airway pressure (PAP) in supine position. He finally settled with CPAP along with position therapy. This case highlights the importance of treating CxSA with basic PAP modes like CPAP along with positional therapy before switching to costlier therapies such as adaptive servo-ventilation...

Recent advances in high-throughput technologies have given rise to collecting large amounts of multidimensional heterogeneous data that provide diverse information on the same biological samples. Integrative analysis of such multisource datasets may reveal new biological insights into complex biological mechanisms and therefore remains an important research field in systems biology. Most of the modern integrative clustering approaches rely on independent analysis of each dataset and consensus clustering, probabilistic or statistical modeling, while flexible distance-based integrative clustering techniques are sparsely covered...

Noninvasive ventilation (NIV), including both continuous and bilevel positive airway pressure, plays a pivotal role in the treatment of acute respiratory failure secondary to acute heart failure. For an appropriate use of NIV, it is essential to consider the underlying pathophysiological principles, the differences between the different modes of ventilation, the main indications, contraindications and complications. The aim of this review is also to give practical guidance on how and when to start NIV at the bedside, how to monitor the response and how to choose the most appropriate interface...

PURPOSE: Although bilevel positive airway pressure (Bilevel PAP) therapy is usually used for overlap syndrome (OS), there is still a portion of OS patients in whom Bilevel PAP therapy could not simultaneously eliminate residual apnea events and hypercapnia. The current study was expected to explore whether auto-trilevel positive airway pressure (auto-trilevel PAP) therapy with auto-adjusting end expiratory positive airway pressure (EEPAP) can serve as a better alternative for these patients...

This paper proposes a new methodology for solving the interval bilevel linear programming problem in which all coefficients of both objective functions and constraints are considered as interval numbers. In order to keep as much uncertainty of the original constraint region as possible, the original problem is first converted into an interval bilevel programming problem with interval coefficients in both objective functions only through normal variation of interval number and chance-constrained programming...

BACKGROUND: High-flow nasal cannulae (HFNC) deliver high flows of blended humidified air and oxygen via wide-bore nasal cannulae and may be useful in providing respiratory support for adult patients experiencing acute respiratory failure in the intensive care unit (ICU). OBJECTIVES: We evaluated studies that included participants 16 years of age and older who were admitted to the ICU and required treatment with HFNC. We assessed the safety and efficacy of HFNC compared with comparator interventions in terms of treatment failure, mortality, adverse events, duration of respiratory support, hospital and ICU length of stay, respiratory effects, patient-reported outcomes, and costs of treatment...

Objective: To compare the incidence and intensity of acute adverse effects and the variation in the temperature of facial skin by thermography after the use of noninvasive ventilation (NIV). Methods: We included 20 healthy volunteers receiving NIV via oronasal mask for 1 h. The volunteers were randomly divided into two groups according to the ventilatory mode: bilevel positive airway pressure (BiPAP) or continuous positive airway pressure (CPAP). Facial thermography was performed in order to determine the temperature of the face where it was in contact with the mask and of the nasal dorsum at various time points...

Although handful tools are available for constraint-based flux analysis to generate knockout strains, most of these are either based on bilevel-MIP or its modifications. However, metaheuristic approaches that are known for their flexibility and scalability have been less studied. Moreover, in the existing tools, sectioning of search space to find optimal knocks has not been considered. Herein, a novel computational procedure, termed as FOCuS (Flower-pOllination coupled Clonal Selection algorithm), was developed to find the optimal reaction knockouts from a metabolic network to maximize the production of specific metabolites...

Postextubation stridor is associated with significant morbidity. It commonly results in extubation failure after established medical treatment fails, such as nebulized epinephrine and/or intravenous steroids. The role of heliox (i.e., combination of helium and oxygen) in managing patients with postextubation stridor has not been fully established. We report two cases of postextubation stridor successfully treated with heliox delivered with bilevel positive airway pressure (BiPAP) after failure of standard medical therapy...
