“Poor Effort” Does Not Account for Reduced Forced Vital Capacity in Asthmatic Children

Forced vital capacity and forced expiratory volume in six seconds as predictors of reduced total lung capacity.

The present study aims to derive guidelines that identify patients for whom spirometry can reliably predict a reduced total lung capacity (TLC). A total of 12,693 lung function tests were analysed on Caucasian subjects, aged 18-70 yrs. Restriction was defined as a reduced TLC. Lower limits of normal (LLN) for TLC were obtained from the European Respiratory Society recommended reference equation...

Low forced vital capacity predicts poor prognosis in gastric cancer patients

Preoperative pulmonary function assessment is used to select surgical candidates and predict the occurrence of postoperative complications. The present study enrolled 1210 gastric cancer patients (949 males and 261 females). Forced vital capacity (FVC) and maximal voluntary ventilation (MVV) were measured as a percent of predicted values. We then analyzed associations between patient pulmonary ...

Forced Vital Capacity (FVC) and Forced Vital Capacity in 1 Second (FEV1) of Apparently Healthy Non-smoker Adult Obese

Physical training does not increase allergic inflammation in asthmatic children.

The effects of a 3-month physical training programme on airway inflammation and clinical outcomes were studied in school-aged children with asthma. Subjects with persistent allergic asthma (aged 12.7+/-3.4 yrs; n = 34) were randomly allocated into training and control groups. Exercise consisted of twice-weekly 50-min sessions for 12 weeks. Inflammation was assessed by levels of exhaled nitric o...

The vital capacity of children.

In 1846 Hutchinson published an exhaustive treatise on pulmonary function, giving an historical review and describing in detail methods for measuring pulmonary ventilation using, apparently for the first time, a spirometer. Most investigators since then have followed Hutchinson's lead and used spirometers to record their measurements. The following simple methods of measurement have been those ...
