[Effect of a face mask on work of breathing in patients with chronic obstructive respiratory disease].
Resistive loading associated with breathing through a face mask (surgeons' paper mask) increases work of breathing significantly after a prolonged period of wearing. The additional resistive breathing due to a face mask may be intolerable for patients with preexisting overloaded respiratory muscle pump and contribute to inspiratory muscle fatigue.
