Decreased Prevalence of Exercise Expiratory Flow Limitation from Pre- to Postpuberty
VENTILATORY CONSTRAINT MATURATION CHILDREN SEX DIFFERENCES
font style='font-size:12px;'>
2017/4/19
Purpose: We recently reported a high prevalence of expiratory flow limitation (EFL) independent of sex in prepubescent children that exceeds the prevalence reported in adults. It is unknown how transp...
Effects of the Menstrual Cycle on Expiratory Resistance During Whole Body Exercise in Females
airway resistance female menstrual cycle exercise
font style='font-size:12px;'>
2015/4/17
Our objective was to determine if the menstrual cycle affected expiratory resistance developed during progressive incremental exercise in females. Eleven females (age = 19.7 ± 1.1 yr., body mass = 58....
End expiratory oxygen concentrations to predict central venous oxygen saturation: an observational pilot study

Influence of increased gas density and external resistance on maximum expiratory flow
human respiratory lung pressure
font style='font-size:12px;'>
2009/7/17
The effect of external resistance on the relationship of expiratory air flow and intrathoracic and mouth pressure on subjects breathing gas of increased density was investigated. Five subjects breathi...
Influence of exercise on maximal voluntary ventilation and forced expiratory flow at depth
CO2 carbon dioxide human
font style='font-size:12px;'>
2009/7/15
Four to six subjects performed maximal voluntary ventilation (MVV) and forced expirations during rest, exercise (50, 125, and 200 W), and inhalation of air and CO2 and air at rest while submerged at p...
Effects of inspiratory and expiratory resistance in divers' breathing apparatus
CO2 carbon dioxide hyperbaric chamber respiratory inspiratory resistance expiratory resistance
font style='font-size:12px;'>
2009/6/5
This study was performed to determine if inspiratory breathing resistance causes greater or smaller changes than expiratory resistance. Unacceptable inspiratory resistances were also determined. Five ...
Peak expiratory flow at increased pressure
Equipment hyperbaric research medical conditions and problems
font style='font-size:12px;'>
2009/5/18
It has been estimated that asthma is as common
amongst divers as in the general population. Thus, asthmatic
individuals may require hyperbaric therapy and monitoring
in this treatment. Asthma is us...

Normal Values of Peak Expiratory Flow Rate in Children from the Town of Babol, Iran
Anthropometrics Children Peak expiratory flow rate PEFR
font style='font-size:12px;'>
2010/2/5
In the management and evaluation of asthma, simple instruments for measurements of peak expiratory flow rate (PEFR) are necessary. The aim of this study was to determine normal PEFR of the healthy chi...

2010/2/26
In women, maximum expiratory pressure increased with volume from 39 to 61 cmH2O and maximum inspiratory pressure decreased with volume from 66 to 28 cmH2O. In men, maximum expiratory pressure increase...
Exercise challenge in patients with asthma whose peak expiratory flow values are controlled within the green zone
airway hyperreactivity exercise-induced asthma green zone peak expiratory flow
font style='font-size:12px;'>
2010/11/29
Recent guidelines for the management of asthma recommend that peak expiratory flow (PEF) should be measured to monitor the level of airflow limitation and to maintain PEF values within the green zone ...
