“…7 The statistical methods suggested by Bland and Altman4 were not used in these studies, but biases estimated at 3%1 and 38 I/min7 were thought to be clinically acceptable and similar to variations between different standard Wright meters. Small variations between instruments were noted with the mini Wright meters but were not regarded as clinically important.…”

Objective-To compare measurements of the peak expiratory flow rate taken by the mini Wright peak flow meter and the turbine spirometer.Design-Pragmatic study with randomised order of use of recording instruments. Results-208 (98%) Of the readings taken by the mini Wright meter were higher than the corresponding readings taken by the turbine spirometer, but the 95% limits of agreement (mean difference (2 SD)) were wide (1 to 173 I/min). Differences due to errors in reproducibility were not sufficient to predict this level of disagreement. Analysis by age, sex, order of use, and the type of expiration did not detect any significant differences.Conclusions-The two methods of measuring peak expiratory flow rate were not comparable. The mini Wright meter is likely to remain the preferred instrument in general practice.

ResumoObjetivo: identificar o número de nebulizações necessárias e a demanda de corticosteróide intravenoso em crianças em crise asmá-tica, a partir de características clínicas e funcionais observadas no momento da admissão na unidade de emergência.Métodos: foram avaliadas prospectivamente 130 crianças em crise asmática, na faixa etária de 1 a 13 anos. No momento da admissão, as crianças foram avaliadas por meio de escore clínico e medidas de saturação arterial de oxigênio (por oximetria de pulso) e de pico de fluxo expiratório. Em seguida, receberam um tratamento padronizado e foram acompanhadas em relação à necessidade de nebulizações consecutivas com ß2 agonista e costicosteróide intravenoso. Através de análise de regressão buscou-se uma correlação dos parâmetros avaliados com o número de nebulizações realizadas e o uso de corticosteróide.Resultados: oitenta e oito crianças (67,7%) receberam de uma até três nebulizações, e 42 crianças (32,3%) receberam seis nebulizações. Sessenta e oito crianças (52,3%) receberam corticosteróide. Os valores iniciais de escore clínico, saturação arterial de oxigênio e pico de fluxo expiratório mostraram uma correlação significativa com o número de nebulizações realizadas e com a necessidade do uso de corticosteróide.Conclusão: com base em nossos resultados, é possível predizer e antecipar, no momento da admissão das crianças em crise asmática na unidade de emergência, a necessidade do uso de corticosteróide e de um maior número de nebulizações, o que pode alterar o prognóstico e o tempo de evolução da crise.J Pediatr (Rio J) 2001; 77 (3): 219-26: asma, criança, asma aguda, tratamento, corticosteróide, ß2 agonista. AbstractObjective: to identify the number of nebulizations needed and the demand for intravenous corticosteroids in children with asthmatic attack, considering clinical and functional characteristics presented at the moment children were admitted to the emergency room.Methods: we prospectively evaluated 130 children with asthmatic attack and from 1 to 13 years of age. At the moment children were admitted, they were evaluated according to clinical score, arterial oxygen saturation (pulse oximetry), and peak expiratory flow. Next, children received a standard treatment and were observed for the number of consecutive nebulizations required and the use of corticosteroid. Using regression analysis, we assessed the parameters evaluated for a correlation with the number of nebulizations and the use of intravenous corticosteroid.Results: eighty-eight children (67.7%) received from 1 to 3 nebulizations and 42 children (32.3%), 6 nebulizations. Sixty-eight children (52.3%) received corticosteroid. The initial values for clinical scores, arterial oxygen saturation, and peak expiratory flow showed a significant correlation with the number of nebulizations required and the need for corticosteroids.Conclusions: according to our results, it is possible to predict and anticipate, at the time chidren are admitted with asthmatic attack, the need for corticosteroid and more nebulizatio...

“…The PEF was measured using the mini-Wright peak flow meter. 15,16 The parameters were assessed before and 20 minutes after the inhalation of 400μg of Salbutamol using a metered dose inhaler (MDI) and a spacer device. For spirometry, a minimum of three and a maximum of eight spirometry maneuvers were done according to ERS/ATS criteria.…”

SUMMARYBackground: Health Related Quality of Life (HRQL) measures can capture the non-respiratory effects of Chronic Obstructive Pulmonary Disease (COPD). However the relationship with Peak Expiratory Flow (PEF) is not well understood Aim: To determine the relationship of PEF and quality of life measurements in patients with COPD Settings and Design: A cross section of consecutive patients in a university clinic Methods: Stable patients with COPD defined by the Global Initiative on chronic Obstructive Lung Disease (GOLD) criteria, were recruited into the study. Spirometry was done using American Thoracic Society's standards and reference equations from African American norms of the US population. Quality of life was measured with the St George's Respiratory Questionnaire (SGRQ) Results: Out of 50 patients recruited for the study, 48 provided complete data with acceptable spirometry and PEF data. The mean (SD) age and body mass index was 68.4 (8.9) years and 21.4 (4.6) kg/m 2 respectively and 96% of the patients were in moderate-severe stages of COPD using the GOLD criteria. Percent predicted PEF correlated with percent predicted FEV1; r= 0.559 p<0.001 and also showed a significant, though moderate correlation between PEF readings and SGRQ scores especially in the activity (r= -0.455 p< 0.01) and total scores (r=-0.415 p<0.01) for pre bronchodilator (BD) percent predicted PEF. In regression analysis, PEF was associated with SGRQ (-0.11 95% CI -0.19, -0.03) after adjusting for age, sex, height, smoking and disease severity Conclusions: PEF correlates with SGRQ scores and may be a useful surrogate for HRQL in patients with COPD
