BACKGROUND AND PURPOSE Lung hyperinflation is a technique used by physiotherapists to mobilize and remove excess bronchial secretions, reinflate areas of pulmonary collapse and improve oxygenation. Hyperinflation may be delivered by the ventilator or manually, by use of a manual resuscitation circuit, depending upon the respiratory and cardiovascular status of the patient. The effects of manual...

It was investigated whether inhaled budesonide reduces lung volumes in a group of asthmatic children with lung hyperinflation. Budesonide (800 mg bid, for 2 months) was administered to 12 asthmatic children (mean age, 11.293.3 years) with lung hyperinflation (TGV]130% predicted and/or RV]140% predicted) in a randomised, placebo controlled, double blind, crossover study. Body plethysmography (pa...

Despite preventive measures, lung hyperinflation is a relatively common complication following single lung transplantation to treat pulmonary emphysema. The progressive compression of the graft can cause mediastinal shift and respiratory failure. In addition to therapeutic strategies such as independent ventilation, the treatment consists of the reduction of native lung volume by means of lobec...

Background. Diagnosis of chronic obstructive pulmonary disease (COPD) is confirmed on spirometry but the diagnosis of emphysema remains problematic. The objective of this study was to evaluate the utility of chest radiograph (CXR) and computed tomography (CT) for the diagnosis of emphysema and to correlate these findings with pulmonary function tests (PFTs). Methods. Thirty-five patients with C...

Daily physical activity is an important outcome variable in patients with chronic obstructive pulmonary disease (COPD) and has shown to be mainly associated with dynamic lung hyperinflation [1]. Physical inactivity is known to cause muscle deconditioning, which increases the ventilatory requirements during exercise, and in turn increases lung hyperinflation and worsens dyspnoea, thus contributi...

A decreased inspiratory capacity (IC)/total lung capacity (TLC) ratio is associated with dynamic hyperinflation and decreased exercise capacity. The present authors hypothesised that static (low IC/TLC) and dynamic hyperinflation impair cardiac function as assessed by oxygen pulse at rest and during cardiopulmonary exercise testing (CPET). Lung function, body mass index, hand grip strength and ...

RATIONALE In patients with acute respiratory distress syndrome (ARDS), a focal distribution of loss of aeration in lung computed tomography predicts low potential for alveolar recruitment and susceptibility to alveolar hyperinflation with high levels of positive end-expiratory pressure (PEEP). OBJECTIVES We tested the hypothesis that, in this cohort of patients, the table-based PEEP setting c...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/ bcr-2013-008668 DESCRIPTION A 14-year-old girl presented with a 1-year history of insidious onset dyspnoea. Three years previously, she had been treated for 6 months with directly observed antituberculous treatment for sputum smear positive pulmonary tuberculosis (TB) and the treatment was suc...
