fibers.
Properties
heat-resistance, low electrical conductivity, flexibility, and high tensile strength were essential factors
The toxic properties of such fibres are dependent upon a diameter narrow enough to allow inhalation deep into the lung, a length that prevents their removal by macrophages, resistance to dissolution in tissue fluid, and a surface able to cause oxidative damage.
Syndrome Air flow Episodes/hr SaO2
UARS No significant decrease >15 No decrease
OSHS Decrease of 30-50% in air flow for >10s >15 May be associated with a decrease of 3-4%
OSAS Cessation of air flow for >10s >5 Usually associated with a decrease of >4%
* All three Syndromes have arousal associated with increasing ventilatory effort and excessive daytime sleepiness
