flow

[flō]
(computer science)
The sequence in which events take place or operations are carried out.
(engineering)
A forward movement in a continuous stream or sequence of fluids or discrete objects or materials, as in a continuous chemical process or solids-conveying or production-line operations.
(fluid mechanics)
The forward continuous movement of a fluid, such as gases, vapors, or liquids, through closed or open channels or conduits.
(geology)
Any rock deformation that is not instantly recoverable without permanent loss of cohesion. Also known as flowage; rock flowage.
(mathematics)
A function from the set of arcs in an s-t network to the nonnegative integers whose value at each arc is equal to or less than the weight of the arc.
(physics)
The movement of electric charges, gases, liquids, or other materials or quantities.

flow

1. See cold flow.
2. A measure of the consistency of freshly mixed concrete, mortar, or cement paste in terms of the increase in diameter of a molded truncated-cone specimen after jigging a specified number of times.
3. That characteristic of a paint which enables it to form a uniform, smooth surface without showing brush marks or other evidence of the method of application.

flow

A stream or movement of air or other fluid, or the rate of fluid movement, in the open or in a duct, pipe, or passage—specifically, airflow.

Flow

(tool)
A companion utility to Floppy by Julian James Bunn <julian@vxcrna.cxern.ch>. Flow allows the user to produce various reports on the structure of Fortran 77 code, such as flow diagrams and common block tables. It runs under VMS, Unix, CMS.

Outcome parameter was peak expiratory flow rate which is a crude method as compared to spirometry.

These show that hand grip strength was positively correlated with BMI upper arm length mean arm circumference and peak expiratory flow rate and all these were statistically significant.
Their peak expiratory flow values fall below 40% of personal best.
There was no difference regarding the primary outcome of morning peak expiratory flow. If you understand the difference between patient- and disease-oriented outcomes, you should say to yourself, "Who cares?" More important, there was no clinically significant difference in the number of courses of budesonide or asthma control scores (0.1 to 0.2 on a 6-point scale), and no difference in quality-of-life scores.
(3) The researchers concluded that the insertion and maintenance of the bronchoscope in the airways had no effect on pulmonary function, but the application of topical lidocaine did cause significant decreases in forced expiratory volume in 1 second (FE[V.sub.1]), forced vital capacity, peak expiratory flow, and peak inspiratory flow.
Guidelines developed for asthma based on pulmonary function testing and peak expiratory flow (PEF) monitoring have gained widespread professional acceptance.
A randomized trial comparing peak expiratory flow and symptom self-management plans for patients with asthma attending a primary care clinic.
Goals of asthma management are to: maintain "normal" (or near normal) pulmonary function, maintain "normal" activity levels, prevent chronic symptoms (coughing or breathlessness at night or after exertion), prevent recurrent exacerbation of asthma, and avoid adverse effects of asthma medications.[1] To measure and monitor pulmonary function, the child with asthma should be encouraged to periodically measure (one or more times daily) peak expiratory flow rates (PEFR).[2] The PEFR reflects the degree of airway obstruction and can be determined by use of a "peak flow meter" which is inexpensive and easily obtainable.
The report recommends that "regularly scheduled, short-acting inhaled beta-2 agonist treatment should be kept to a minimum." Beta-2 agonists offer relief but don't control symptoms, affect peak expiratory flow rates, or alter airway hyperresponsiveness.
In the study named " The Negative influence of Cigarette Smoke on Passive Smokers - Deteriorated Pulmonary Function Tests and Increased Urine Cotinine Levels" which study, correlated the deterioration of pulmonary functions, such as increase in secretions, decrease in Forced expiratory flow (FEF) 50% (predictor of large airways) and decrease of PEF (peak expiratory flow) with urinary cotinine levels on the amount of passively exposed cigarette smoke.
The respiratory parameters including FEV1%, FVC%, FEV1/FVC%, maximal voluntary ventilation (MVV), and peak expiratory flow rate (PEFR) were measured using SPIROLAB II (MIR) software.
