Acoustic Analysis of Breath Sounds as a Surrogate for Gas Exchange Thresholds
Acoustic Analysis Breath Sounds Gas Exchange Thresholds
2015/5/21
Respiratory gas exchange threshold measurements are a reference standard for measuring sustainable exercise capacity (McLellan and Skinner, 1981). A recent consensus report suggested that ‘threshold b...

Breath-holding spells: Prevalence and risk factors in under 6-year old children at south of Tehran
Breath-holding spells Syncope Cerebral-anoxia Apnea
2009/12/24
To determine breath- holding spells (BHS) prevalence and risk factors in under 6- year- old children, we interviewed mothers of 400 children in a cross- sectional study in 5 health centers at south of...
Flavoring agents present in a dentifrice can modify volatile sulphur compounds (VSCs) formation in morning bad breath
Halitosis Volatile sulfur compounds Dentifrices Flavoring agents BANA test
2009/10/16
This study aimed to evaluate the effects of a flavor-containing dentifrice on the formation of volatile sulphur compounds (VSCs) in morning bad breath. A two-step, blinded, crossover, randomized study...
Interfacial Effects of In Situ-Synthesized Ag Nanoparticles on Breath Figures
Interfacial Effects In Situ-Synthesized Ag Nanoparticles Breath Figures
2010/7/16
In the present study, we introduced Ag nanoparticles into polymer and found for the first time that Ag nanoparticles can induce the formation of breath figure (BF) arrays on polymer surfaces. The effe...
Researchers in Israel have invented a new type of breath test for detecting lung cancer in patients using sensors built with gold nanoparticles. Although the analysis of breath particulates is not a n...
Left-ventricular performance in man during breath-holding and simulated diving
cardiovascular human breath holding
2009/7/20
We measured left-ventricular (LV) systolic time intervals (STI) to determine whether breath-holding and simulated diving evoke a depression of LV performance in man similar to that previously demonstr...
Effectiveness of a breath during exercise in a hyperbaric environment
human exercise ventilation
2009/7/16
During vigorous foot-pedal exercise at 6.75 ATA, three subjects had lower total ventilation, larger functional residual capacity (FRC), and higher PCO2 in end-expired and mixed-expired gas than during...
Patterns of wet suit diving in Korean women breath-hold divers
human breath-hold wet suit thermal protection
2009/7/15
Work shifts, diving pattern, diving lung volumes, and counterweights were studied in professional Korean women breath-hold divers wearing wet suits. One of the major differences, compared with their d...
Circulatory functions during immersion and breath-hold dives in humans
