Outcome parameter was peak expiratory flow rate
which is a crude method as compared to spirometry.
Prediction of asthma episodes in children using peak expiratory flow rates
, medication compliance and exercise data.
EIA, defined as a decrease in FEV or peak expiratory flow rate
of [is equal to] 15%, was found in 36 (4%) of the children.
For this study, the PFT measures - forced vital capacity (FVC), forced expiratory volume 1(FEV1) and peak expiratory flow rate
(PEFR) - were taken using computerised spirometry device (Spiro USB 5050), and the American Thoracic Society (ATS) guidelines2,11 for spirometry were strictly followed.
Peak expiratory flow rates
. Indian J Physiol Pharmacol 2005;49:8-18.
This is a cross-sectional study done at a tertiary care hospital to compare the peak expiratory flow rate
with the help of "Mini-Wright" peak flow meter among females, normal healthy subjects and subjects who are asthmatics of age group 20-40 years.
Routine measurement of peak expiratory flow rate
does not predict subsequent asthma exacerbations.
A group of 801 student athletes aged 13-18 years completed an 8-minute run; peak expiratory flow rate
(PEFR) was measured at the end of the run and 3 and 6 minutes later.
-- The origin of acute dyspnea can be distinguished using a quick calculation based on peak expiratory flow rate
and arterial oxygen pressure, Dr.
There is improvement of forced expiratory volume in one second ([FEV.sub.1]), forced vital capacity (FVC), [FEV.sub.1]/FVC, peak expiratory flow rate
(PEFR), forced expiratory flow rate 25-75% ([FEF.sup.25-75]), specific airway conductance (sGAW) (P < 0.001), and significant reduction in RAW (P < 0.001) after 4th and 8th weeks of yoga practice in Group A as compared to Group B [Tables 1-3].
Peak expiratory flow rate
(PEFR): This is the maximum flow rate that can be sustained for a period of 10 ms by maximum forceful expiration following maximum inspiration.
Maximum peak expiratory flow rate
was seen in age group younger than 20 years.
