Decreased Prevalence of Exercise Expiratory Flow Limitation from Pre- to Postpuberty
VENTILATORY CONSTRAINT MATURATION CHILDREN SEX DIFFERENCES
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
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
emergency medicine emergency department central venous oxygen saturation
2014/11/28
Background A non-invasive surrogate measurement for central venous oxygen saturation (ScVO2) would be useful in the ED for assessing therapeutic interventions in critically ill patients. We hypothesiz...
The effect of 8 week pulmonary rehabilitation programme on chest mobility and maximal inspiratory and expiratory mouth pressure in patients with bronchial asthma
Breathing disorders musculoskeletal disorders breathing exercises soft tissue techniques
2009/12/25
Bronchial asthma (AB) can lead not only to breathing disorders but also to musculoskeletal disorders. Breathing and musculoskeletal disorders can lead to health problems and decreased quality of life....
Estimate of maximum expiratory flow based on the equal pressure point concept and Weibel's lung model
human Weibel's lung model Maximal Expiratory Flow Rate
2009/7/20
Estimate of maximum expiratory flow based on the equal pressure point concept and Weibel's lung model.
Influence of increased gas density and external resistance on maximum expiratory flow
human respiratory lung pressure
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
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
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
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...
Review of Positive End - Expiratory Pressure and Its Application in the Hyperbaric Environment
Positive End - Expiratory Pressure PEEP
2009/5/8

Normal Values of Peak Expiratory Flow Rate in Children from the Town of Babol, Iran
Anthropometrics Children Peak expiratory flow rate PEFR
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...
Maximum static inspiratory and expiratory pressures with different lung volumes
Maximum static inspiratory expiratory pressures different lung volumes
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
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 ...
Peak expiratory flow in normal healthy Japanese adults: Comparisons with values reported in other races
comparisons with other races normal Japanese adults peak expiratory flow regression equations ventilatory capacity
2010/11/24
From the regression equations, predicted values of PEF can be derived for any Japanese adult aged 15-74 years. We were able to obtain predicted equations for PEF in normal Japanese adults using both ...
An advanced expiratory circuit for the recovery of perfluorocarbon liquid from non-saturated perfluorocarbon vapour during partial liquid ventilation: an experimental model
perfluorocarbon liquid non-saturated perfluorocarbon vapour an experimental model
2010/2/26
From 14.2 mL (47%) to 27.3 mL (91%) of the infused 30 mL of FC-77 was recovered at the flow rates studied. Significantly higher FC-77 recovery was obtained at lower flow rates (ANOVA with Bonferroni's...
