1. An alternative approach for blocking the superior trunk of the brachial plexus evaluated by a single arm clinical trial
Abstract Background Interscalene brachial plexus block is associated with phrenic nerve paralysis. The objective of this study was to evaluate an alternative approach to interscalene brachial plexus blocks in terms of efficacy, grade of motor and sensory blockade, and phrenic nerve blockade. Methods The study was prospective and interventional. The ten liv

2. Parameter estimation of an artificial respiratory system under mechanical ventilation following a noisy regime
Abstract Introduction: This work concerns the assessment of a novel system for mechanical ventilation and a parameter estimation method in a bench test. The tested system was based on a commercial mechanical ventilator and a personal computer. A computational routine was developed do drive the mechanical ventilator and a parameter estimation method was util

3. Lower limb muscle strength is associated with functional performance and quality of life in patients with systemic sclerosis
Background: Complaints of peripheral muscle weakness are quite common in patients with systemic sclerosis (SSc). It is likely that the muscle impairments may reduce the patients' exercise performance, which in turn may decrease their functional capacity and exert a direct impact on their quality of life. Objectives: To assess the peripheral and respiratory

4. Within-breath respiratory impedance and airway obstruction in patients with chronic obstructive pulmonary disease
OBJECTIVE: Recent work has suggested that within-breath respiratory impedance measurements performed using the forced oscillation technique may help to noninvasively evaluate respiratory mechanics. We investigated the influence of airway obstruction on the within-breath forced oscillation technique in smokers and chronic obstructive pulmonary disease patien

5. Relationship between body balance, lung function, nutritional status and functional capacity in adults with cystic fibrosis
BACKGROUND: Cystic fibrosis (CF) is a hereditary condition in which lung disease affects all patients. In addition to pulmonary involvement, the multisystemic components of CF cause significant physical limitations. However, the impact of lung function on balance control in CF has not been studied. OBJECTIVE: To assess body balance in adults with CF an

6. Oscillation mechanics of the respiratory system in never-smoking patients with silicosis: pathophysiological study and evaluation of diagnostic accuracy
OBJECTIVES: Silicosis is a chronic and incurable occupational disease that can progress even after the cessation of exposure. Recent studies suggest that the forced oscillation technique may help to clarify the changes in lung mechanics resulting from silicosis as well as the detection of these changes. We investigated the effects of airway obstruction in s

7. Efeito do uso de salbutamol nas propriedades mecânicas do sistema respiratório de indivíduos saudáveis, tabagistas e portadores de doença pulmonar obstrutiva crônica / Effect of salbutamol on the mechanical properties of the respiratory system of healthy individuals, smokers and patients with chronic obstructive pulmonary disease
A doença pulmonar obstrução crônica (DPOC) é caracterizada pela limitação de fluxo parcialmente reversível, classificada por níveis de obstrução pós-broncodilatador. Há várias evidências de que o FEV1 sozinho não é capaz de mostrar a broncodilatação de pacientes com DPOC, mesmo naqueles que apresentam melhora clínica. A técnica de oscila

8. Imagem e mecânica pulmonar regional em duas estratégias protetoras de ventilação mecânica (ARDSNet versus PEEP ajustada pela tomografia de impedância elétrica): um estudo de longo prazo em modelo experimental / Image and regional lung mechanics in two protective ventilatory strategies (ARDSNet versus PEEP adjusted by electrical impedance tomography): a long term experimental model study
Introdução: As estratégias ventilatórias protetoras têm contribuído para a redução da letalidade da Síndrome do Desconforto Respiratório Agudo (SDRA), mas ainda está em debate qual, entre as diversas existentes, é a mais eficaz. A estratégia ARDSNet, muito utilizada na prática clínica, prioriza a redução do volume corrente para minimizar a h

9. Estudo dos efeitos da posição prona na distribuição regional da aeração e da perfusão pulmonar através da tomografia de impedância elétrica e da tomografia computadorizada multislice / Effects of prone position on regional distribution of lung aeration and perfusion. Analysis by electrical impedance tomography and computer tomography
Introdução: A utilização da posição prona melhora significativamente a oxigenação de pacientes com síndrome do desconforto respiratório agudo (SDRA). Estudos prévios sugerem que o recrutamento das regiões pulmonares colapsadas e pobremente aeradas é um dos possíveis mecanismos responsáveis pela melhora da oxigenação, no entanto, os mesmos ai

10. Efeitos hemodinâmicos de duas estratégias de ventilação mecânica protetora em um modelo suíno de Síndrome do Desconforto Respiratório Agudo / Hemodynamic effects of two strategies of protective ventilation in porcine model of acute respiratory distress syndrome
A Síndrome do Desconforto Respiratório Agudo (SDRA) cursa com insuficiência respiratória e necessidade de ventilação mecânica invasiva (VMI). A mortalidade desta síndrome é elevada, mas pode ser reduzida com o uso de estratégias protetoras de ventilação mecânica que usam baixo de volume corrente (VC), geralmente 6ml/Kg ou menos, para minimizar a

11. Total inspiratory and expiratory impedance in patients with severe chronic obstructive pulmonary disease
OBJECTIVES: Several studies have confirmed the high potential of the forced oscillation technique for the assessment of respiratory modifications related to chronic obstructive pulmonary disease. However, most of these studies did not employ within-breath analyses of the respiratory system. The aim of this study is to analyze respiratory impedance alteration

12. Nutritional status is related to fat-free mass, exercise capacity and inspiratory strength in severe chronic obstructive pulmonary disease patients
INTRODUCTION: Being overweight or obese is associated with a higher rate of survival in patients with advanced chronic obstructive pulmonary disease (COPD). This paradoxical relationship indicates that the influence of nutritional status on functional parameters should be further investigated. OBJECTIVE: To investigate the impact of nutritional status on bod
