Measurement of peak expiratory flow rates in 220 normal children from 4.5 to 18.5 years of age. J Pediatr. 1963;62(2):186-9.Murray, A. B., and Cook, C. D.: Measurement of peak ex- piratory flow rates in 220 normal children from 4.5 to 18.5 years of age, J Pediatr 62: I 86...
000 lung function measures in 2728 asthmatic children evaluated at a tertiary referral center. The mean FEV1of the cohort studied was 92.7% of predicted, with 77% of the values within the normal range (>80% of predicted). In contrast, the mean FEF25–75was 78% with only 27.7% of the...
Find the best peak flow meter manufacturers and suppliers in the uSA with a broad range of configurations for their peak flow meters with accurate measuring.
BACKGROUND--Variability of peak expiratory flow (PEF) has been proposed as a surrogate for bronchial hyperresponsiveness. The normal range of variability of PEF for children has been reported and the test has been used to screen for asthma in population based studies. However, there is little in...
ventricular wall (green arrows in Fig.3b1) and a normal pressure to the gray matter-CSF interface (blue arrows in Fig.3b2). These loading conditions represent the cyclic brain deformations caused by a combination of hemodynamic forces and CSF flow59. The lateral ventricles, in particular, ...
The new, low-range Ferraris pocket peak flow meter was compared with the well established low-range mini Wright peak flow meter for measuring peak flow rates in children. The peak flow meters were compared by performing three forced expirations using each meter, in 50 children. On average the...
For example, during the initial stages of testing [0°/90°]4s specimens, they have experienced longitudinal matrix cracks and recorded amplitude in the range of 50–60 dB. When the tensile stress increases, the specimen undergoes both longitudinal and transverse fiber/matrix interface crack and...
It is found, surprisingly, that with the presence of the flow-deflecting means at the entry to the chamber 16, a satisfactory smaller scale version of the known instrument can be provided for a substantially lower operating range than that of the known instrument. Measurement of peak flows in...
If the receiving system 104 receives a spurious transmission at a much higher data rate, such as 2 Mbps per second, a conventional peak flow detection system may determine that the new peak value is 2 Mbps per second. When the system returns to its normal range of 1 Mbps, the system ...
