Healthy people are generally breathing through nose during sleep, but oral breathing will be given rise to if the nasal cavity is gradually being closed. Nasal closure or even nasal congestion leads to open mouth during snoring, which causes the tongue base collapse, the origin of OSAS. Thus, if a simple home device with only a microphone can automatically monitor our snores at bedside and dete...

Injuries due to inhalation of hot gas is commonly encountered when dealing with fire and combustible material posing a threat to the human life. Various studies have been carried out in the literature investigating the heat and mass transfer characteristics in the human respiratory tract. This study focuses on assessing the injury taking place in the upper human respiratory tract and identifyin...

Continuous positive airway pressure (CPAP) is the gold standard for the treatment of obstructive sleep apnea (OSA). Although CPAP was originally applied with a nasal mask, various interfaces are currently available. This study reviews theoretical concepts and questions the premise that all types of interfaces produce similar results. We revised the evidence in the literature about the impact th...

In this study we have demonstrated that by combining data from several recent controlled human exposure studies it is possible systematically to relate increases in airways resistance to the rate of SO2 exposure (Dmin) in the exercising asthmatic. It was determined that the mode of SO2 exposure (oral vs. oronasal) greatly influences the degree of response in the asthmatic. Forced oral breathing...

the main purpose of this study was to determine which correlate, perceived motor competence or motor skill competence, best predicts girls' physical activity behavior.a sample of 352 girls (mean age=8.7, sd=0.3 yr) participated in this study. to assess motor skill competence and perceived motor competence, each child completed the test of gross motor development-2 and physical ability sub-scale...

Noninvasive positive-pressure ventilation (NPPV) is increasingly being used in the care of patients suffering acute respiratory failure. High-level evidence supports the use of NPPV to treat exacerbation of chronic obstructive pulmonary disease (COPD). NPPV has also been successfully used with selected patients suffering acute hypoxemic respiratory failure and to allow earlier extubation of mec...
