Nevertheless, the decrease in expiratory resistance after bronchodilator therapy can be indirectly estimated by measuring expiratory flow at a given elastic recoil pressure (ie Pp) before and after bronchodilator delivery [ 31].
The Wright Peak Flow Meter was developed to measure Peak Expiratory Flow [ 3].
These new skills enable practitioners to perform certain routine, frequently provided, easily trainable, and low-risk procedures (e.g., monitoring vital signs, measuring blood glucose level, carrying out venipuncture for blood sampling, measuring peak expiratory flow rate, examining for breast lumps and providing advice on health promotion) that can help bring about more integrated care.
Each student measured peak expiratory flow rate three times a day for 42 days.
A measure of expiratory flow limitation may be useful in characterising how an athlete may respond to exercise and training in hypoxia.
Study treatments were taken at approximately the same time every morning and evening and immediately after measuring peak expiratory flow (PEF).
Each practice nurse reviewed children at monthly intervals for six months, measured peak expiratory flow (recording the best reading from three attempts), assessed asthma control, and asked parents whether the bedding covers issued were still being used.
We measured peak expiratory flow rates and specific IgE for inhalant and food allergens at 4 years of age, and selected children with asthma symptoms up to 4 years of age (n = 542) and controls (n = 542) for genotyping.
The research team trained the community coordinators in the informed consent procedures, completion of questionnaires and symptom diaries, use of Piko meters (nSpire Health, Longmont, CO) for measuring peak expiratory flow rate and forced expiratory volume in one second (FEV1), and correct placement of temperature loggers and nitrogen dioxide diffusion tubes.
Methods: Four similarly designed double-blind studies individually confirmed equivalence between combination and concurrent therapy on the basis of the primary efficacy measure (morning peak expiratory flow [PEF]).
