This is a study of the ventilatory functions of 1,805 normal Mexican-American, white, and black students of six public schools in Houston, Texas, with ages ranging from 7 to 20. A roll-seal piston type spirometer was used. The best performed forced vital capacity curve of each student was selected by the computer program from which the following measurements were extracted: FVC, FEV₁, FEV₁/FVC ratio, PEFR, and MMEF. Each student also had the peak expiratory flow rate measured by the Wright peak flowmeter to establish normal values with this instrument. Significant differences of lung volume and flow rate exist among the three races, and between male and female subjects. Prediction equations and prediction curves for each race and sex are presented. The results of the present study are compared with those of previously published works.

The majority of that research, however, was not designed with the aim of producing spirometric-prediction equations (Kiyamu et al., 2012; Frisancho et al., 1997; Weitz et al., 2016; Kiyamu et al., 2015), while other studies had limitations that made the results unreliable for routine clinical use (Rojas and Dennis, 2010; Santolaya et al., 1984). As a consequence, spirometric studies performed on those subjects are interpreted and reported using reference equations generated at low altitude (Quanjer et al., 1993; Hankinson et al., 1999; Roca et al., 1998; Hsu et al., 1979; Crapo et al., 1981,1990; Quanjer et al., 2012; Galíndez et al., 1998; Pérez Padilla et al., 2006). The American Thoracic Society (ATS) and European Respiratory Society (ERS) recommend studying a healthy sample of the local community in an attempt to validate published pulmonary function reference equations (Miller et al., 2005a,b; Pellegrino et al., 2005).
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.
To obtain spirometric prediction equations from a healthy subset of adults living in Argentina at 3440 m above sea level.
We randomly recruited 172 healthy men and 235 healthy women, ages 20–70. Spirometry was done according to ATS/ERS standards. Reference equations were computed using regression analysis.
The resulting prediction equations:
For men:
FVC = 0.0407*height (cm)–0.0250*age(years)–0.81;SEE 0.518.
FEV1 = 0.0327*height (cm)-0.0282*age(years)-0.25;SEE 0.414.
For women:
FVC(liters) = 0.0464*height(cm)–0.0222*age(years)–2.62;SEE 0.396.
FEV1(liters) = 0.0343*height(cm)–0.0218*age(years)–1.40;SEE 0.316.
These results establish spirometric-prediction equations for the population studied and further demonstrate: (1) a linear decline of FVC and FEV₁ with age for both genders, (2) age and height satisfactorily predict both parameters, (3) supra-normal values for this population were found when compared to those predicted by lowland Caucasian equations.

Citation Excerpt :
The currently recognized noninfectious pulmonary manifestations of chronic GVHD are bronchiolitis obliterans syndrome (BOS) and its earlier precursor, which is lesser degrees of airflow obstruction [65]. Dyspnea, wheeze, or cough occur frequently in chronic GVHD and clinical examination, pulmonary function tests (PFTs) [66-68], radiologic studies, and bronchoalveolar lavage help to distinguish BOS from other pulmonary diseases (eg, pulmonary thromboembolism, cryptogenic-organizing pneumonia, radiation-induced lung injury), extrapulmonary diseases (eg, effusions, subcutaneous sclerosis), and lung infections. Air trapping and bronchiectasis may result from advanced BOS, infections, or both.
The 2006 National Institutes of Health (NIH) Consensus paper presented recommendations by the Ancillary Therapy and Supportive Care Working Group to support clinical research trials in chronic graft-versus-host disease (GVHD). Topics covered in that inaugural effort included the prevention and management of infections and common complications of chronic GVHD, as well as recommendations for patient education and appropriate follow-up. Given the new literature that has emerged during the past 8 years, we made further organ-specific refinements to these guidelines. Minimum frequencies are suggested for monitoring key parameters relevant to chronic GVHD during systemic immunosuppressive therapy and, thereafter, referral to existing late effects consensus guidelines is advised. Using the framework of the prior consensus, the 2014 NIH recommendations are organized by organ or other relevant systems and graded according to the strength and quality of supporting evidence.
Diagnosis and differentiation of late non-infectious pulmonary complications after allogeneic haematopoietic stem cell transplantation
2013, Acta Haematologica Polonica
The role of pulmonary function monitoring after allogeneic haematopoietic stem cell transplantation and the prognostic significance of detected airflow impairment are discussed by the authors. The purpose of the work is also to clarify the nomenclature and diagnostic criteria of non-infectious pulmonary complications after allotransplant. The incidence and diagnostic criteria of representative conditions, as bronchiolitis obliterans and cryptogenic organizing pneumonia are presented. The significance of radiologic findings, bronchoscopy and lung biopsy in diagnostic strategy is also discussed. We believe that the presented review of the current multidisciplinary knowledge on late non-infectious pulmonary complications in patients after stem cell transplantation may be useful in improving the quality of long-term care of those patients.

Pulmonary function, the physical factors that determine it and its importance for the physiotherapist
2011, Revista Iberoamericana de Fisioterapia y Kinesiologia
El fisioterapeuta emplea, dentro de sus herramientas de valoración, aquellas destinadas a la medición de la función pulmonar. Todos los factores que afectan la función pulmonar deben ser conocidos de manera exhaustiva por el fisioterapeuta. Este trabajo pretende esclarecer aquellos factores, de carácter físico, que condicionan la función pulmonar.
Revisar la bibliografía disponible que relacione los factores físicos que influyen en la función pulmonar.
Revisión bibliográfica sistemática en las bases de datos: CINAHL, ScienceDirect, Ovid, Scopus y PubMed. Con antigüedad inferior a 25 años.
Se obtuvo un número total de 90 artículos. Los autores han reconocido que entre los factores físicos de la función pulmonar se encuentran la edad, el sexo, la talla, el peso y el grupo étnico. A estos factores se han sumado en los últimos años, gracias a numerosos autores, los musculoesqueléticos, como la morfología de la caja torácica y el desarrollo muscular.
Los diferentes estudios asocian la edad, el sexo, la raza, el peso y la altura, y los factores musculoesqueléticos torácicos a la función pulmonar. Sin embargo, son necesarios más estudios que expliquen esta influencia.
Within their assessment tools, the physical therapist uses those designated for the measurement of lung function. Having extensive knowledge about the physical factors affecting normal lung function is important for the physical therapist. This paper aims to clarify those physical factors that condition pulmonary function.
To review the bibliography available that relate the physical factors having an influence on pulmonary function.
The search was made with the following databases: CINAHL, Ovid, Scopus, ScienceDirect and PubMed, with time antiquity limited to the last 25 years.
A total of 90 articles were obtained from the search. The authors have stated that physical factors of pulmonary function include age, sex, height, weight and ethnic group. In recent year, many authors have also added musculoskeletal factors, morphology of the thoracic cavity and muscle development.
The different studies associate age, sex, race, height and weight and thoracic musculoskeletal factors to pulmonary function. However, more studies are needed to explain this influence.
Bronchiolitis obliterans syndrome epidemiology after allogeneic hematopoietic cell transplantation
2011, Biology of Blood and Marrow Transplantation
Bronchiolitis obliterans syndrome (BOS) is a pulmonary complication of allogeneic hematopoietic cell transplantation (aHCT). Recent National Institutes of Health consensus diagnostic criteria for BOS have not been assessed in a clinical setting. Modified National Institutes of Health diagnostic consensus criteria for BOS were applied to evaluate its prevalence, risk factors, and outcomes in the modern era of aHCT. Pulmonary function tests from 1145 patients were screened to identify patients with new-onset airflow obstruction. Clinical records were reviewed to exclude pulmonary infection and other causes. The overall prevalence of BOS among all transplanted patients was 5.5%, and 14% among patients with chronic graft-versus-host disease (cGVHD). The median time from transplant to meeting spirometric criteria for BOS was 439 days (range: 274-1690). Although many previously identified risk factors were not significantly associated, lower baseline FEV₁/FVC ratio (P = .006), non-Caucasian race (P = .014), lower circulating IgG level (P = .010), and presence of cGVHD (P < 0.001) were associated with an increase in risk, with the latter associated with a 10-fold increase in risk. Multivariate analysis indicated that BOS conferred a 1.6-fold increase in risk for mortality after diagnosis. These results suggest that the National Institutes of Health diagnostic criteria can reliably identify BOS, and that it is more prevalent than previously suggested. Spirometric monitoring of high-risk patients with cGVHD may permit earlier detection and intervention for this often-fatal disease.
