Spirometry is a basic test for assessing pulmonary function. This test is largely used nowadays, because of its low cost and acceptable reproducibility. Its feasibility has been shown even in 2 to 6 year old children. Considering the importance of applying standardized techniques in spirometry, a committee of specialists on pulmonary function from Chilean Respiratory Society, published in 2006 a procedures manual on spirometry. By 2014 new spirometric reference equations for healthy Chilean adults were published and more recently in 2017, the American Thoracic Society and the European Respiratory Society have published recommendations for a standardized pulmonary function report. The aim of this manual is to report international norms performing spirometry, in order to promote their application in clinical and laboratory practice. In addition, this reviewed manual encloses newest concepts on spirometry in preschool children, reference values, and a general assent way for interpreting and reporting spirometric values at clinical and at laboratory work is proposed.
Omalizumab treatment on severe asthma patients: pediatric experience in Chile and literature review This paper presents clinical experience with Omalizumab treatment in 8 pediatric patients in Chile. All children presented difficult to control asthma despite receiving high intensity treatment, with low quality of life. All patients were studied in order to discard errors in asthma diagnosis and to evaluate asthma treatment adherence and inhalation technique. After evaluation, patients proven to have severe therapy resistant asthma were indicated treatment with Omalizumab. Significant clinical improvement was observed, with reduced asthma symptoms and number of exacerbations, as well as an improved quality of life. Omalizumab showed a good safety profile with mild and transient adverse reactions in 6 administrations of a total of 122.
A brief guideline for carrying out pulse oximetry in the clinical practice is presented. This guideline was written by the Pulmonary Function Commission of the Chilean Respiratory Disease Society. Basic aspects for applying this non-invasive measurement to adults and infants as well as carefulness in interpreting its results are briefly described.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
