Hot-thermistor spirometry for the artificial ventilation of infants
… ventilation. The principles of hot-thermistor spirometry were investigated both theoretically and experimental.ly to develop new temperature-compensation techniques and to predict the effect of gas composition changes on spirometer celebration. New electronic circuits were developed which …

The Determination of Lung Function Using Impulse Oscillometry and Spirometry
… using oscillometry by comparing the values to spirometry. Oscillometry is a less invasive procedure for respiratory testing than spirometry testing. One hundred and forty-two participants completed self-assessment questionnaires, along with body composition measurements and at least three …

The quality and variation of spirometry reads for testing lung function in children in sub Saharan Africa
… the basis of lung function assessments and spirometry the most widely used diagnostic tool for lung function testing. The effectiveness of spirometry to distinguish between normal and abnormal lung function has been realised in adults; however, there is an observed history of …

A prospective cohort study of the correlation between chest circumference and spirometry measurements over a 19-week intense training programme
… Reasons for this include the inconsistent use of spirometry and the inability to produce acceptable and reproducible results. Chest circumference measurements have been positively correlated with pulmonary function in healthy individuals and those with pulmonary pathologies, thus potentially …

Lung function in smokers - Aspects on COPD diagnosis and associations to atherosclerosis and alcohol consumption
… criteria. Aspects of lung function besides spirometry in smokers fulfilling none, either or both of the spirometric criteria for COPD are not well known. Early COPD is hard to reveal, as spirometry has a poor relationship to symptoms. A promising method for early diagnosis of COPD is Impulse …

Lung function in healthy South African adult females
Background: Accurate and appropriate spirometry reference values allow for early detection of respiratory illness and perform an important role in monitoring lung health. There is, in general, a scarcity of data from Africa, and the Global Lung Initiative (GLI) has published global reference …

The effect of lymphatic pump techniques on the FEV and FVC measurements in people with asthma: a pilot study
… without asthma. All 30 subjects performed spirometry testing, followed by the single application of a lymphatic pump technique to the upper chest. Spirometry measurements were again taken immediately after this technique, and then ten and twenty minutes thereafter. No significant changes in …

Effort-Independent Asthma Severity Classification
… asthma as an alternative to the gold standard, spirometry. Capnography shows promise in the detection of similar pulmonary disorders, and would serve as a noninvasive and effort-independent tool, providing critical information to clinicians when patients are unable or unwilling to comply with …

The long-term respiratory health effects of the herbicide, paraquat, among Western Cape workers
… respiratory symptoms and confounding variables. Spirometry and gas transfer were measured and chest radiographs performed. Oxygen desaturation on exercise testing was by oximetry during a modified stage one exercise test. Results: No association was found between long-term paraquat exposure and …

Novel methods within a randomised controlled trial in respiratory disease
… medicine.<br/><br/>Results:<br/>Remote spirometry was completed by patients at home with moderate adherence and was not significantly different to supervised spirometry performed at clinic visits for a number of lung function tests (FEV1, FVC, FEF25-75 and PEF). The EMBARC definition was …

The Use of Osteopathic Manipulation in a Clinic and Home Setting to Address Pulmonary Distress as Related to Asthma in Southwest Virginia
… and posttest measurements included: participant spirometry FEV1, FVC, and PEF; thoracic excursion upper and lower rib cage motion; and a five-question rating scale to determine current asthma symptoms. A ten-minute OMT session included an individualized thoracic and rib screening and treatment, …

Physiological and metabolic characterization of older adults. Especial focus on cardiorespiratory fitness and its role on cognitive function
… resting cardiovascular, metabolic and spirometry parameters, and CRF by the modified Bruce incremental test; ii) field assessments of Senior Fitness Test Battery and handgrip test; iii) self-reported questionnaires and interviews on sociodemographic characteristics, activities of daily …

Nutrition, Inflammation and Lung Function in Middle-aged Men
… anthropometric measurements and lung function by spirometry. Each individual spirometry trace (baseline and 10 year follow-up) was reviewed for validity using ATS/ERS criteria. Plasma levels of C-Reactive Protein (CRP), antioxidant vitamins (A and E) and carotenoids were measured in the stored …

Prediction of post-tuberculosis lung damage using CT lung imaging measures among adults in Malawi
… important in determining concurrent abnormal spirometry at baseline in post-TB individuals. These features were not useful in predicting spirometry outcomes at 12 months after treatment completion. However, there is need for further validation of these results in other settings and the …

Is lower socio-economic status associated with more impaired health care access and poorer quality of life in patients with COPD? What is the role of psychosocial factors in this relationship?
… Anxiety and Depression Scale (HADS), and spirometry.<br/>Results: COPD confirmed by spirometry in 176 (85%) participants. 38.6% female, mean age 69 years, distribution of disease severity (GOLD): Grades 1-4 (mild – very severe) = 15%; 51%; 30%; 5%. Lower SES was not associated with more …

Effects of xanthine oxidase inhibitors in pulmonary hypertension associated with chronic lung disease
… Respiratory Questionnaire, Short Form 36, spirometry and six-minute walk test (6MWT).The mean age was 71 years, the mean FEV1 was 60% with mean resting SaO2 of 96%. After 12 months, there was no significant change in RVM. There were also no significant changes in other cardiac parameters …

LUNG CLEARANCE INDEX: a new biomarker of ventilation inhomogeneity in pediatric respiratory diseases.
Conventional spirometry has long been considered the primary test of respiratory function deficit in children and adults. However, performing forced breathing manoeuvres is challenging in an uncooperative child. Furthermore, recent evidence suggests that conventional spirometry is not sensitive for …

The Relationship Between Lean Body Mass, Resting Metabolic Rate, and Peak Oxygen Consumption in Spinal Cord-Injured and Able-Bodied Individuals
… bodied). RMR was assessed using open circuit spirometry. The amounts of LBM, MFL, and BMC were assessed using dual energy x-ray absorptiometry (DXA). Peak oxygen consumption was assessed using arm crank ergometry (ACE) with open circuit spirometry. All statistical analyses were conducted at …
