The tighter a mask fits the more likely it is to reduce blood oxygen levels and to increase the amount of carbon dioxide being inhaled. It should be noted that optimal oxygen intake in humans should, according to the US Occupational Safety and Health Administration, be between 19.5 and 23.5% and that any human-occupied airspace where oxygen measures less than 19.5% should be labelled as not safe for workers. However, the percentage of oxygen inside a masked airspace generally measures 17.4% within seconds of putting on the mask. A tighter fitting mask will result in lower oxygen levels and higher carbon dioxide levels. Lower oxygen levels and increased levels of carbon dioxide stimulate greater inspiratory flow – leading to a greater risk that loose fibres from the facemask will be inhaled.
