The mean normalized peak expiratory flow rates for the three trimesters and postpartum were 0.92 +/- 0.036, 0.95 +/- 0.032, 0.94 +/- 0.030, and 0.95 +/- 0.031 (values +/- 95% CI). CONCLUSIONS: This study demonstrates that peak expiratory flow rate does not change with pregnancy and ...
The normal range and reproducibility of common physiologic parameters for 99mTc-MAG3 renal studies were quantitated in normal subjects. METHODS: Six females and six males in each of three age groups, 21-40, 41-60 and 61-80 yr, were each studied twice. Renal clearance (camera based method)...
A Study was undertaken to establish the normal values of peak flow rate using Wright peak flowmeter at several Japanese chest clinics and laboratories. The subjects were 417 healthy children aged 6 to 15 years. Prediction equations and regression lines are presented for each sex. The predicted val...
In comparison, other ratios of perfusion indices (e.g. upslope index) for stress and rest systematically underestimate the flow reserve but may still prove useful for the detection of disease, assuming that one has established the normal range of the index. Full size image FT-CMR has shown ...
As Barton and Choubey (1977) suggested, the values of M at peak strength are equal to 1 and 2 for low and high normal stresses, respectively, although Skinas et al. (1990) stated that M can reach a value of 5 in the post-peak range at high normal stresses. Finally, they proposed ...
Production operators establish normal operating ranges. The principal concern with the four main process variables is that their sensing devices, which respond to conditions outside normal ranges, have enough time to respond before problems occur. For example, the normal range for a separator’s liqu...
Most turbulent phenomena are non-linear, complex and have broad range of scales that are difficult to completely resolve. Progress is made only in minute steps and enlightening models are rare. Herein, we undertake the effort to bundle several experimental and numerical databases to overcome some ...
Recently, it has been suggested that peak expiratory flow (PEF) may be determined by the wave speed flow-limiting mechanism. In six normal male subjects (age = 33 +/- 8 years) performing expiratory forced vital capacity (FVC) maneuvers, a negative expiratory pressure (NEP) of -10 cm H2O...
The RV chamber volumes are greater in the athletes heart than in normal individuals [51]. The athlete’s RV volumes may exceed CMR criteria for abnormality in arrhythmogenic right ventricular cardiomyopathy (ARVC). However, RVEF is in the normal range of nonathletes even in the athlete heart (...
