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...

Quantification of subjective attributes expressed as functions of design variables is a significant challenge in creating product design optimization models. For example, the objective assessment of a vehicle’s environmental friendliness is typically based on fuel economy and emissions. But some design variables such as a vehicle’s silhouette (twodimensional body shape) may create a subjective ...

Laboratory animal workers are at risk of developing allergic symptoms, of which asthmatic symptoms are the most severe. The aim was to study the relationship between allergic symptoms due to working with rats and variability and changes in peak expiratory flow (PEF). Several indices were used on the basis of the amplitude of the PEF or the differences in PEF between days with and without exposu...

OBJECTIVE This study examined the associations between social network types and peak expiratory flow (PEF), and whether these associations were mediated by social and physical activities and mood. METHOD Nine hundred twenty-four community-dwelling Chinese older adults, who were classified into five network types (diverse, friend-focused, family-focused, distant family, and restricted), provid...
