Lung deflation and oxygen pulse in COPD: results from the NETT randomized trial.
We examined whether lung deflation improves oxygen pulse, a surrogate marker of stroke volume. In 129 NETT patients with cardiopulmonary exercise testing (CPET) and arterial blood gases (ABG substudy), hyperinflation was assessed with residual volume to total lung capacity ratio (RV/...
What is the clinical value of lung volumes?
Lung volumes are considered part of a complete pulmonary function test, but their value for enhancing clinical decision making is unknown. Unlike spirometry and diffusing capacity of the lung for carbon monoxide (D(LCO)), which do contribute to confirming or excluding a diagnosis, th...
Lung volumes and emphysema in smokers with interstitial lung abnormalities.
We looked for interstitial lung abnormalities in 2416 (96%) of 2508 high-resolution computed tomographic (HRCT) scans of the lung obtained from a cohort of smokers. We used linear and logistic regression to evaluate the associations between interstitial lung abnormalities and HRCT measurements of to...
[Long-term results of airways' injury after a methane explosion].
Injuries caused by thermal trauma more and more often affect people and they are an important problem of contemporary medicine. It is connected with the civilization development. Burn concerns not only the exterior integuments of the body but also airways, in those cases, the death rate among those w...
Sizing the lung of mechanically ventilated patients.
We conclude that body mass is a powerful determinant of lung volume and plateau airway pressure. Effective lung size can be easily estimated from a recruitment maneuver derived inspiratory capacity measurement and body mass index....
Exhaled nitric oxide and clinical phenotypes of childhood asthma.
Our aims were to evaluate whether exhaled NO (FENO(0.05)) is independently associated (1) with underlying pathophysiological characteristics of asthma such as airway tone (bronchodilator response) and airway inflammation (inhaled corticosteroid [ICS]-dependant inflammation), and (2) with clinical ph...
Decreasing cardiac chamber sizes and associated heart dysfunction in COPD: role of hyperinflation.
We studied the relationship of lung function with heart size and heart dysfunction and associated consequences for 6-min walk distance (6MWD) in patients with COPD of different severitites. In 138 patients with COPD (Global Initiative for Obstructive Lung Disease [GOLD] I-IV), we mea...
Upper limb exercises using varied workloads and their association with dynamic hyperinflation in patients with COPD.
Our objective was to evaluate the dynamic hyperinflation development during ULE using three constant workloads. This was a prospective, randomized protocol involving 24 patients with severe COPD (FEV(1) < 50%) performing an endurance symptom-limited arm exercise of up to 20 min in an...
The effect of lung volume on efficacy of hands-on defibrillation during each phase of ongoing manual cardiopulmonary resuscitation.
Comparison of plethysmographic and helium dilution lung volumes: which is best for COPD?
In the setting of airflow obstruction, Pleth systematically overestimates lung volume relative to He or thoracic imaging despite adherence to current recommendations for proper measurement technique....
