In many population based studies, Peak Expiratory Flow Rate (PEFR) is considered as a simple and useful screening method for persons with respiratory problems. PEFR may also vary with environment, region and anthropometric factors. The present study was aimed to construct a PEFR nomogram in no...
Acute effects of Asian dust events on respiratory symptoms and peak expiratory flow in children with mild asthma. Randomized Trial of Interventions to Improve Childhood Asthma in Homes with Wood-burning Stoves Compared to a spirometer, the resistance of this flow meter causes less variability in meas...
Are peak flow and symptom measures good predictors of asthma hospitalizations and unscheduled visits? These findings suggest that in a research setting, peak flow monitoring in children did not add prediction beyond that obtained from symptom reports. ... KM Mortimer,S Redline,M Kattan,... - 《...
A survey of three indices of ventilatory capacity, forced expiratory volume in 1 second (FEV 1), forced vital capacity (FVC) and peak expiratory flow rate (PEFR), was undertaken on 3490 Chinese inhabitants of Hong Kong. Nomograms have been constructed for the prediction of these three indices...
About This equation is taken from Hankinson et al (1999), based on evaluation of 7429 asymptomatic, lifelong nonsmoking participants aged 8 to 80 years in the third National Health and Nutrition Examination Survey (NHANES III). This survey included caucasian, African-American, and Mexican-American...

Children with high flow velocity in the ICA and MCA of 200 cm/s time average mean of the maximum (TAMM) or higher had a 10%per year risk of first stroke that was reduced to <1%with regular red cell transfusion (reduction of hemoglobin S <30%). The clinical application of the STOP ...
There is a nonexistence theorem about prediction in this area, in the sense that if we could predict what we are going to know at some time in the future, we would not have to wait, for we would know it now. It is not surprising, therefore, that the great technical changes have neve...
Landgraf later admitted that he hadn’t foreseen the sheer volume that would come with the streaming media explosion, which changed that prediction. But in 2022, Landgraf called it again, proclaiming during FX’s summer 2022 TCA session that “2022 will be the high watermark” of scripted ...
