1. Cardiovascular involvement in COVID-19: not to be missed
Abstract In December 2019, a striking appearance of new cases of viral pneumonia in Wuhan led to the detection of a novel coronavirus (SARS-CoV2). By analyzing patients with severe manifestations, it became apparent that 20 to 35% of patients who died had preexisting cardiovascular disease. This finding warrants the important need to discuss the influence of

2. Accuracy of chest auscultation in detecting abnormal respiratory mechanics in the immediate postoperative period after cardiac surgery
RESUMO Objetivo: Investigar a acurácia da ausculta torácica na detecção de mecânica respiratória anormal. Métodos: Foram avaliados 200 pacientes sob ventilação mecânica no pós-operatório imediato de cirurgia cardíaca. Foi avaliada a mecânica do sistema respiratório - complacência estática do sistema respiratório (Cest,sr) e resistência d

3. Inflammatory lung injury in rabbits: effects of high-frequency oscillatory ventilation in the prone position
RESUMO Objetivo: Comparar os efeitos das posições prona e supina durante ventilação oscilatória de alta frequência (VOAF) sobre oxigenação e inflamação pulmonar, lesão histológica e estresse oxidativo em um modelo de lesão pulmonar aguda (LPA) em coelhos. Métodos: Trinta coelhos Norfolk machos brancos foram submetidos à LPA por meio de lavag

4. The influence of inspiratory muscle training combined with the Pilates method on lung function in elderly women: A randomized controlled trial
OBJECTIVE: Aging is progressive, and its effects on the respiratory system include changes in the composition of the connective tissues of the lung that influence thoracic and lung compliance. The Powerbreathe® K5 is a device used for inspiratory muscle training with resistance adapted to the level of the inspiratory muscles to be trained. The Pilates meth

5. Chronic heart failure modifies respiratory mechanics in rats: a randomized controlled trial
ABSTRACT Objective To analyze respiratory mechanics and hemodynamic alterations in an experimental model of chronic heart failure (CHF) following myocardial infarction. Method Twenty-seven male adult Wistar rats were randomized to CHF group (n=12) or Sham group (n=15). Ten weeks after coronary ligation or sham surgery, the animals were anesthetized and sub

6. 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

7. 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

8. A sigmoidal fit for pressure-volume curves of idiopathic pulmonary fibrosis patients on mechanical ventilation: clinical implications
OBJECTIVE: Respiratory pressure-volume curves fitted to exponential equations have been used to assess disease severity and prognosis in spontaneously breathing patients with idiopathic pulmonary fibrosis. Sigmoidal equations have been used to fit pressure-volume curves for mechanically ventilated patients but not for idiopathic pulmonary fibrosis patients.

9. Comportamento da mecânica ventilatória durante a realização de um atendimento de fisioterapia respiratória
Question: Can Respiratory therapy alter the lung mechanics in patients with invasive mechanical ventilation? The data available in the literature remain controversial. This study aims to assess the changes of pulmonary mechanics in patients with invasive mechanical ventilation, comparing hemodynamic and ventilatory parameters one hour prior to application of

10. Influence of the ageing process on the resistive and reactive properties of the respiratory system
INTRODUCTION: In an increasingly old society, the study of the respiratory system changes and new techniques dedicated to older patients are of interest in physiologic studies as well as in the diagnosis of respiratory diseases. OBJECTIVES: (1) To investigate the impact of ageing on the resistive and reactive properties of the respiratory system, and (2) to

11. Efeito da obesidade sobre a forÃa dos mÃsculos respiratÃrios e centro respiratÃrio
Background: The obesity affects many organs and systems of human body, prejudicing vital functions by immunologic, circulatory, hormonal and respiratory functions. On the respiratory system, obesity results in a reduction of lung volumes and flows. Also take a reduction on the respiratory compliance and an increment on the total respiratory resistance. Metho

12. Estudo da complacÃncia do sistema respiratÃrio de indivÃduos obesos, com diferentes nÃveis de Ãndices de massa corpÃrea, pelo emprego da oscilometria de impulso
Obesos podem apresentar reduÃÃo da complacÃncia pulmonar e diminuiÃÃo dos volumes pulmonares, cuja magnitude pode ser influenciada pelo grau de obesidade. O objetivo desse estudo foi analisar a complacÃncia do sistema respiratÃrio e as variÃveis espiromÃtricas de indivÃduos obesos com diferentes nÃveis de IMC. Foram realizadas espirometrias e OI d
