1. Effects of non-invasive ventilation and posture on chest wall volumes and motion in patients with amyotrophic lateral sclerosis: a case series
ABSTRACT Background The effects of non-invasive ventilation (NIV) on the breathing pattern and thoracoabdominal motion of patients with amyotrophic lateral sclerosis (ALS) are unknown. Objectives 1) To analyze the influence of NIV on chest wall volumes and motion assessed by optoelectronic plethysmography in ALS patients and 2) to compare these parameters

2. Análise da função pulmonar e análise cinemática da mobilidade tóracoabdominal em sujeitos tetraplégicos praticantes de rúgbi em cadeira de rodas / Analysis of pulmonary function and chest wall kinematic analysis in wheelchair rugby players
O trabalho teve como objetivo estudar o efeito de um ano de treinamento de rúgbi em cadeira de rodas sobre a função pulmonar e a mobilidade toracoabdominal de tetraplégicos através da espirometria e da análise cinemática, sendo dividido em três partes. Na primeira parte, sete tetraplégicos foram submetidos à espirometria antes e depois de treinamen

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. Análise da cinemática dos compartimentos da parede torácica nas posições supino e sentada de pacientes com esclerose lateral amiotrófica
Amyotrophic Lateral Sclerosis (ALS) is characterized by deterioration of upper and lower motor neurons. The main components, which alter the respiratory muscles are the inspiratory, expiratory, and bulbar, leading to chronic respiratory failure. One way to improve gas exchange of these individuals is by employing non-invasive ventilation (NIV). Therefore, th

5. Os efeitos da cirurgia de redução de volume pulmonar nos volumes operacionais da caixa torácica em repouso e durante exercício em pacientes com DPOC
Melhor sincronia entre os compartimentos da caixa torácica tem sido identificada como um dos fatores para a redução da dispnéia e aumento da capacidade de exercício após a cirurgia de redução de volume pulmonar (CRVP).Para elucidar os efeitos da CRVP nas variações de volume da caixa torácica em repouso e durante exercício, seis pacientes (VEF1% 2

6. Rib cage mechanics after median sternotomy.
A substantial reduction in lung volumes occurs after sternotomy, but the mechanism or mechanisms are unclear. Measurements were made of lung volumes and of chest wall motion with four pairs of magnetometers (two pairs for anteroposterior rib cage, one for lateral rib cage, and one for anteroposterior abdominal dimensions) in 16 men before and one week and th

7. Effect of bracing on respiratory mechanics in mild idiopathic scoliosis.
The use of a corrective orthopaedic brace is an established form of management for patients with progressive idiopathic scoliosis. Thirteen patients with mild idiopathic scoliosis were studied with and without the corrective brace applied. Lung volumes and the pattern of chest wall and abdominal movement were measured during quiet breathing. Transdiaphragmat

8. An optical method of studying the shape and movement of the chest wall in recumbent patients.
A method of optical mapping has been developed that allows the shape and motion of the chest wall to be studied in recumbent patients. It uses a single camera at a fixed viewpoint to determine the three dimensional coordinates of the visible surface of the body, and hence to measure the volume and shape of the visible segment. Measurements on different test

9. Responses of upper airway, intercostal and diaphragm muscle activity to stimulation of oesophageal afferents in dogs.
The effects of oesophageal distension on respiratory patterns and the moving average electromyogram (e.m.g.) activity of three upper airway muscles--the alae nasi, the genioglossus, and the posterior cricoarytenoid--and four chest wall muscles--the costal and crural diaphragm and the inspiratory and expiratory intercostals--were examined in ten anaesthetized

10. 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

11. Effects of pneumothorax or pleural effusion on pulmonary function.
The effects of pneumothorax or pleural effusion on respiratory function as measured by the commonly applied tests were investigated by studying 13 patients (six with pneumothorax, seven with effusion) with and, as far as possible, without air or fluid in the pleural cavity. Measurements included spirometric volumes, carbon monoxide transfer factor (TLCO), an

12. Differential lung function in an infant with the Swyer-James syndrome.
A previously healthy two year old boy had an adenoviral infection at the age of 13 months and developed hyperlucency of the left lung, chronic respiratory distress, and failure to thrive. Bronchodilators and steroid treatment had no effect. Radionuclide lung scans using an intravenous bolus of xenon-133 both before and after treatment showed substantially re
