Introduction. PEF has never been characterized among healthy Moroccan adults. The objective of this study is to describe the values of PEF among healthy Moroccan adults, to study its relationship with anthropometric parameters (gender, age, height, and weight), to compare spirometric and flowmetric PEF, to establish the prediction equations for PEF, and to study the correlation between PEF and ...

The specific purpose of this case study was to investigate whether forced expiratory technique (FET) improves the peak expiratory flow compared to coughing in a 53-year-old man with amyotrophic lateral sclerosis (ALS) who presented with bulbar symptoms. Approximately 12 months after diagnosis, his peak cough flow did not exceed 160 L/min, and cough became ineffective. However, FET could generat...

The efficacy and tolerability of salmeterol, 50 micrograms b.i.d. was compared for three months with salbutamol, 200 micrograms q.i.d., administered from metered-dose inhaler. For the following nine months, safety and clinic lung function was monitored on salmeterol, 50 micrograms b.i.d., compared with salbutamol, 200 micrograms b.i.d. This comparison was made in a multicentre, double-blind, pa...

In a double-blind, cross-over study, 9 children (7-13 yrs old) with stable, moderate asthma inhaled formoterol (6, 18 and 54 micrograms) and salbutamol (100, 300 and 900 micrograms) at hourly intervals, in order to compare the peak effect of cumulative doses of the two drugs. One hour after the last dose, 1 mg salbutamol was inhaled to ensure that maximum bronchodilatation was obtained. The for...

1. Arterial plasma histamine concentrations, forced expiratory volume in 1.0 s (FEV1.0) and peak expiratory flow rate were determined in nine patients with exercise-induced asthma and in five control subjects before and after 8 min of cycle-ergometer exercise. 2. In the controls neither FEV1.0 nor peak expiratory flow rate fell by more than 5% in any individual during the 30 min postexercise pe...

The aim of this study was to look at differences in countermovement jump (CMJ) performance and selected kinetic parameters in athletes of different training backgrounds and to examine the relationships between these parameters. The subjects were 14 endurance athletes, 12 sprinters, and 13 fire-fighter aspirants (controls); each performed two CMJ on a force plate. The best jump of two attempts w...

Background: PEF is a reasonably good measure of ventilatory function. It varies with various anthropometric parameters, geographical location of the subjects as well as various disease processes. Objective: To assess the relationship between PEF and certain selected anthropometric parameters and to devise prediction equation based upon these parameters. Materials and Methods: Three hundred heal...

INTRODUCTION Respiratory muscle training is the most commonly used method to revert respiratory muscle weakness; however, the effect of protocols based on non-respiratory maneuvers has not been adequately studied in the pediatric population. The objective of this study was to establish the effect of abdominal muscle training on respiratory muscle strength and forced expiratory flows in healthy ...

Oral terbutaline, in gradually increasing doses from 2.5 to 10 mg three times daily (t.i.d.) was administered to 12 patients with chronic bronchial asthma. There was a linear relationship between dose and steady-state plasma concentrations in individual patients, but the plasma levels varied fourfold between patients taking similar doses. The need for other medication tended to decrease, and th...
