Peak expiratory flow rate was determined via standard peak expiratory flow rate device in both the groups after the inhalation of standard dose of salbutamol.
Peak Flow Meter: Peak flow meter was used to measure air flowing out of the lungs this test is called peak expiratory flow rate (PEFR).
Peri, "Peak expiratory flow rate in south Indian adults," Indian Journal of Physiology and Pharmacology, vol.
The primary variables measured included forced vital capacity (FVC), forced expired volume in one second (fEv1), FVC/FEV1, peak expiratory flow rate (PEFR), and maximal voluntary ventilation (MVV).
Peak expiratory flow rate measurements are useful to diagnose COPD
The authors extracted data for the following outcomes: subjective well-being, asthma symptom scores, use of medication, days of sick leave from school or work, number of unscheduled visits to a physician or hospital, forced expiratory volume in 1 second ([FEV.sub.1]), peak expiratory flow rate (PEFR), and provocative concentration that causes a 20% fall in [FEV.sub.1] (PC20).
After 6 months, morning peak expiratory flow rate (primary outcome measure) did not differ significantly between the as-needed combination therapy group and the regular twice-daily beclomethasone or regular combination therapy groups, suggesting "mild persistent asthma may not require regular treatment with inhaled corticosteroids, but rather only as-needed use of an inhaled corticosteroid and an inhaled bronchodilator" (N.
Each student measured peak expiratory flow rate three times a day for 42 days.
One clinical study (Jones et al 1992a) compared the expiratory flow rates between circuits and found a higher peak expiratory flow rate in the Laerdal circuit at low peak inspiratory pressure (13 cm[H.sub.2]O) compared with a higher peak expiratory flow rate in the Mapleson C at a high peak inspiratory pressure (38 cm[H.sub.2]O).
6) PEFR this is the peak expiratory flow rate, i.e., the very fastest speed at which air left the lung.
In the recent collaboration with the Koto Hospital in Tokyo, the company has confirmed that a long-time ingestion (at least 6 months) of tomato juice helps alleviate the subjective symptoms of BA while improving the peak expiratory flow rate, an index of BA.
