1. Ventilatory demand and dynamic hyperinflation induced during ADL-based tests in Chronic Obstructive Pulmonary Disease patients
ABSTRACT Background Airflow limitation frequently leads to the interruption of activities of daily living (ADL) in patients with Chronic Obstructive Pulmonary Disease (COPD). These patients commonly show absence of ventilatory reserve, reduced inspiratory reserve volume, and dynamic hyperinflation (DH). Objective To investigate ventilatory response and DH

2. Avaliação de hiperinsuflação dinâmica em pacientes com linfangioleiomiomatose através de teste de exercício cardiopulmonar e verificação da resposta à broncodilatação / Evaluation of dynamic hyperinflation in patients with lymphangioleiomyomatosis with cardiopulmonary exercise testing and verification of the response to bronchodilator
INTRODUÇÃO: Linfangioleiomiomatose (LAM) é uma doença rara, caracterizada pela proliferação de células musculares lisas atípicas ao redor de vias aéreas, vasos sanguíneos e linfáticos, com formação de cistos pulmonares difusos. Na prova de função pulmonar (PFP), a doença se caracteriza por padrão obstrutivo, aprisionamento aéreo e redução

3. Dynamics of chest wall volume regulation during constant work rate exercise in patients with chronic obstructive pulmonary disease
This study evaluated the dynamic behavior of total and compartmental chest wall volumes [(V CW) = rib cage (V RC) + abdomen (V AB)] as measured breath-by-breath by optoelectronic plethysmography during constant-load exercise in patients with stable chronic obstructive pulmonary disease. Thirty males (GOLD stages II-III) underwent a cardiopulmonary exercise t

4. Daily activities are sufficient to induce dynamic pulmonary hyperinflation and dyspnea in chronic obstructive pulmonary disease patients
OBJECTIVE: The aim of this study was to measure dynamic lung hyperinflation and its influence on dyspnea perception in moderate and severe chronic obstructive pulmonary disease patients after performing activities of daily living. METHODS: We measured inspiratory capacity, sensation of dyspnea, peripheral oxygen saturation, heart rate and respiratory rate in

5. Análise Comparativa dos Efeitos da Combinação Fumarato de Formoterol e Brometo de Tiotrópio versus Monoterapia com Fumarato de Formoterol na Hiperinsuflação Pulmonar Dinâmica e na Tolerância ao Exercício em Pacientes com Doença Pulmonar Obstrutiva Crônica Moderada à Grave / Effects of Formoterol versus Formoterol plus Tiotropium on Exercise Tolerance in COPD
It is currently unclear whether the additive effects of a combination between a longacting b2-agonist and the antimuscarinic tiotropium bromide (TIO) on lung function are actually translated into higher exercise tolerance in patients with chronic obstructive pulmonary disease (COPD). On a double-blind and cross-over study, 33 patients with moderate to severe

6. Efeitos da pressão expiratória positiva na hiperinsuflação dinâmica em pacientes portadores de doença pulmonar obstrutiva crônica submetidos ao exercício
A hiperinsuflação dinâmica (HD) é considerada um importante contribuinte para a sensação de dispnéia e interrupção do esforço físico em pacientes portadores de doença pulmonar obstrutiva crônica (DPOC). Diversas estratégias são testadas para tentar amenizar a HD e, frequentemente, utiliza-se a capacidade inspiratória (CI) para avaliar esse ef

7. Efeito imediato da pressão positiva continua nas vias aereas não invasiva no volume pulmonar expiratorio final de pacientes com doença pulmonar obstrutiva cronica / Immediate effects of non invasive continuous positive airway pressure in end-expiratory lung volume in chronic obstructive pulmonary disease patients
Bachground: Flow limitation and dynamic hyperinflation are common findings in COPD patients. Inspiratory capacity (IC) has been proposed as a simple method to assess changes in end-expiratory lung volume (EEL V) and lung hyperinflation. However, few studies verified if the application of continuous positive airway pressure (CP AP) could decrease lung hyperin

8. Pulmonary characteristics in COPD and mechanisms of increased work of breathing
Mechanical characteristics and gas exchange inefficiencies of the lungs contribute to increased work of ventilation in chronic obstructive pulmonary disease (COPD) at rest and exercise, and the energy cost of ventilation is increased in COPD at any external work level. Assuming typical ventilatory variables and respiratory characteristics, we estimated the r

9. The Lazarus phenomenon
Even though Lazarus phenomenon is rare, it is probably under reported. There is no doubt that Lazarus phenomenon is a reality but so far the scientific explanations have been inadequate. So far the only plausible explanation at least in some cases is auto-PEEP and impaired venous return. In patients with PEA or asystole, dynamic hyperinflation should conside
