Statement on New Reference Values for Spirometry

Reference values for spirometry in preschool children.

OBJECTIVES Reference values for lung function tests differ in samples from different countries, including values for preschoolers. The main objective of this study was to derive reference values in this population. METHODS A prospective study was conducted through a questionnaire applied to 425 preschool children aged 3 to 6 years, from schools and day-care centers in a metropolitan city in B...

Spirometry reference values in the Brazilian population

The aim of the present study was to provide new spirometry reference equations in a sample of the Brazilian population for the following parameters: forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1/FVC ratio, peak of expiratory flow (PEF), forced expiratory flow at 50% (FEF50%), 75% average vital capacity (FEF25-75%), and average forced expiratory flow time (FEFT)....

All-Age Multi-Ethnic Reference Values for Spirometry Advantages Consequences

Spirometry reference values for Navajo children ages 6-14 years.

Spirometry is the most important tool in diagnosing pulmonary disease and is the most frequently performed pulmonary function test. Since respiratory disease is the single greatest cause for morbidity and mortality on the Navajo Nation, the purpose of this study was to create new age and race-specific pulmonary nomograms for Navajo children. Five hundred fifty-eight healthy children, ages 6-14 ...

Spirometry reference values for an andean high-altitude population

We compared the spirometric values of people living at High Altitude at the Andean Plateau with those predicted for lowland population. RATIONALE Spirometry reference values are not yet available for the millions of people living at high altitude in the Andean High Plateau. OBJECTIVE To obtain spirometric prediction equations from a healthy subset of adults living in Argentina at 3440m abov...
