Two European studies have reported that airborne iron was possibly associated with a decline in peak expiratory flow
rate (PEFR), production of phlegm, or exacerbation of respiratory symptoms (Dusseldorp et al.
Peak expiratory flow
rates should not be used for the diagnosis or staging of COPD.
The researchers recorded the best of three peak expiratory flow
measurements taken before and after the OMT or sham procedure.
The team found that lead and manganese were linked with significant reductions in peak expiratory flow
rate, regardless of whether a child had either of the tested gene polymorphisms.
It has been hypothesised that a higher peak expiratory flow
rate, tidal volume and airway pressure would be more efficient in secretion removal and reversing atelectasis in an intubated patient (Kim et al 1986, King et al 1992, Maxwell and Ellis 1998).
Conclusions: Peak expiratory flow
was the most important predictive value for determining the risk of death in patients who required hospitalization for acute exacerbation of chronic obstructive pulmonary disease.
Guidelines developed for asthma based on pulmonary function testing and peak expiratory flow
(PEF) monitoring have gained widespread professional acceptance.
PHT also will demonstrate the latest capabilities in seamless ePRO integrations with Peak Expiratory Flow
(PEF) and glucose measurement devices and other eClinical Systems.
studied the effects of 8 wk of EMST in persons with MS and found that following 4 wk of detraining, no significant decrease in MEP was found and peak expiratory flow
for cough remained significantly above baseline .
The most commonly reported AEs were asthma, peak expiratory flow
(PEF) rate decrease, nasopharyngitis and headache.
Nelson and his coworkers showed in a 544-patient, 16-week randomized trial that patients homozygous for arginine at codon position 16 of the beta-2 adrenergic receptor did not have worse morning peak expiratory flow
than those with other genotypes.
The current standard practice for diagnosis, management and monitoring of asthma patients are peak expiratory flow
(PEF) measurements, pulmonary function tests and clinical symptoms.
