Peak flow rates are commonly split into three zones. The colors of a traffic light – green, yellow, red – represent these zones. Green means your peak flow rate is 80%-100% of normal. Yellow means it is between 50-80%. Red means it is less than 50%. ...
Our study evaluated the ability of early peak expiratory flow rates (PEFR) to be predictive of hospital admission while double blinding the measurements and using a standardized treatment protocol and specific admission criteria. The measurements were recorded prior to and after initial therapy. Eighty...
The basic measurement is peak flow rates and the following diagnostic criteria are used by the British Thoracic Society: • =20% difference on at least three days in a week for at least two weeks;• =20% improvement of peak flow following treatment, for example: o 10 minutes of ...

(the largest amount of air that can be inhaled or exhaled), peak flow rate (which measures the fastest speed at which an individual can blow air out of their lungs), and forced expiratory volume (the largest amount of air that can be exhaled in one second). Once the doctor has tested...
An evaluation of the accuracy of Assess and MiniWright peak flowmeters. With the advent of small inexpensive peak flowmeters, the at-home monitoring of peak flow rates has become an invaluable aid in the treatment of asthmatic ... SM Shapiro,JM Hendler,RG Ogirala,... - 《Chest》 被引量...
The patient's current preventer device had a significant influence on pass rates for both the R5 and R0 test, indicating that those used to using a pMDI were more likely to fail at R5 and those familiar with a DPI device were more likely to fail at R0, the latter being consistently ...
[38]Only 2 of the 8 studies investigating hospital admission rates reveal a significant effect of MgSO4.[38]Conversely, 6 of the 9 studies investigating treatment with nebulized MgSO4compared to placebo reveal a favorable effect on the FEV1and peak expiratory flow rate.[38]These results somewhat...
Your epinephrine levels and peak expiratory flow rates are lowest at about 4:00 a.m., while histamine levels tend to peak at this same time. This decrease in epinephrine levels may predispose you to nocturnal asthma during sleep. How Is Nocturnal Asthma Treated? There is no cure for ...
Peak flow rates and inhaler us ahre useful indicators, but a patient-focused approac nshould additionally include measures such as limitatio of f activities. If consultations offer the prospects o aechieving changes that are meaningful to patients, th therapeutic partnership might become more ...
