• Description:
  Respirators (respiratory personal protector devices) are used by many industrial workers for protection against inhaled toxins. While it was considered traditionally that ventilatory limitation accounted for poor tolerance of them by many workers, more recent analyses have suggested that tolerance is multi-factorial. Understanding of the factors leading to respirator tolerance is likely to improve the design of respirators, establish appropriate medical certification procedures, and provide insight into causes for workers who are particularly intolerant. Several studies have suggested that the respiratory pattern, rather than simply respiratory work to overcome resistance of the respirator, may be important as a determinant of the effect of respirators. Previous studies of respiratory control adaptation to respirator use have emphasized respiratory timing and intensity control. This study evaluated another aspect, the switching of airflow from the nasal route to the oral route. This can affect respiratory sensation directly, or by changing inspired air conditions, or total airway resistance. [Description provided by NIOSH]
