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...
According to the Asthma and Allergy Foundation of America, older adults, low-income individuals, and Black, Hispanic, and American Indian/Alaska Native people have disproportionately higher rates of asthma in the U.S., compared to the general population. They also have the highest rates of deaths...
There has been some controversy concerning increased rates of asthma in countries where childhood vaccination is widespread. Studies have indicated that only one vaccine, pertussis vaccine, may give rise to asthma; however, this positive association has not been successfully confirmed. In a reverse sce...
Although peak expiratory flow rates are often measured, this test is a measure of large airway function only, is effort dependent, and may be unreliable in an anxious, untrained patient. The major value of peak flow measurements in acute asthma is to provide an objective trend indicative of ...
[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...

Consequently, asthmatics have higher respiratory resistance levels and lowered levels of respiration, as measured by peak expiratory flow rates (PEFR) or forced expiratory volume (FEV) (Danker, Miklich, Pratt, & Creer, 1973).This is a preview of subscription content, log in via an institution...
We know that if you are dealing with extremely low peak flow rates, for example below 40 L/min, the patient is in dire need of severe emergency attention and observation. Below 25 L/min, it is likely that the patient is going to need intervention with intubation and mechanical ventilation...
Asthma Rates on the Rise The number of people with asthma has been going up steadily in the U.S. for decades. Some researchers suggest it's because of better hygiene: The theory is that fewer childhood infections lead to under-developed immune systems, which means a greater risk of asthma...
Clinical implications of having reduced mid forced expiratory flow rates (FEF25-75), Independently of FEV₁, in adult patients with asthma. PLoS One. 2015;10(12):e0145476. doi:10.1371/journal.pone.0145476 (Open in a new window)PubMed (Open in a new window)Web of Science ®(Open ...
