The identification, prevention, and prompt treatment of exacerbations are major objectives of asthma management. We looked at change in PEF, symptoms, and use of rescue agonists during the 425 severe exacerbations that occurred during a 12-month parallel group study (FACET) in which low and high doses of budesonide with and without formoterol were compared in patients with asthma. Oral corticos...

Studied the influence of actual and false peak flow (PEF) information on dyspnea (breathlessness) in two experiments, each with 30 children with and 30 without asthma (7-17 years). Dyspnea, PEF, and lung function were measured before and after standardized physical exercise. Dyspnea was measured with a visual analog scale. PEF was measured with a peak flow meter and used for manipulation of dys...

High intensity pulsed electric field (PEF) processing involves the application of pulses of high voltage (typically 20 80 kV/cm) to foods placed between 2 electrodes. PEF treatment is conducted at ambient, sub-ambient, or slightly above ambient temperature for less than 1 s, and energy loss due to heating of foods is minimized. For food quality attributes, PEF technology is considered superior ...

Methods Prospective collected database was conducted from December 2014 to April 2015. Weak cough was defined by peak expiratory flow (PEF) < 60 L/min. The PEF was measured with Cosmed Pony Graphic spirometer v.4.0 S-CZ before extubation, for the patients mechanically ventilated >24 h, who passed successfully SBT at least of 30 min of pressure support 5-8 cmH2O, CPAP, or T-T. The patients were ...

OBJECTIVE To determine the success rate and correlates of ambulatory peak expiratory flow (PEF) monitoring in an epidemiologic study. DESIGN An observational survey. SETTING Several communities in California. PARTICIPANTS We studied 1,223 nonsmoking men and women (mean age, 66 years) from an established cohort. OUTCOME MEASURES A standard respiratory symptoms and diagnoses questionnaire...

The purpose of this study was to investigate the effectiveness combined pulsed electric fields (PEF) and antimicrobial packaging treatment in maintaining quality stability orange juice stored at 10 °C. Orange treated by PEF glass jars with caps coated µL carvacrol essential oil (AP). Microbial reductions physiochemical properties samples were determined after treatments during storage subjected...

PURPOSE To examine whether the bronchodilatory effect of atropine differs in the evening from the morning. METHODS Thirteen adult healthy volunteers with no oral medication intake were studied. At 1600, peak expiratory flow (PEF) was measured three times, and the highest value recorded. Subsequently, the volunteer received 0.01 mg(-1) x kg(-1) atropine im, and the PEF was measured every 30 mi...

Pulsed electric field (PEF) is considered to be a very promising technology for mild cell disruption. The application of PEF for microalgae that have a rigid cell wall, however, is hampered by the presence of that rigid outer cell wall. A cell wall free mutant of C. reinhardtii was used to mimic pretreated microalgae with removed cell wall, to investigate the possibility of using PEF for protei...

Peak expiratory flow (PEF) monitoring is recommended in asthma guidelines as a tool for assessing severity, monitoring response to treatment, detecting exacerbations, identifying triggers, and providing objective justification for treatment to the patient, but some clinicians have expressed concerns about its relevance in the management of asthma. We have identified a sevenfold variation in the...
