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.
长时间佩戴与通过面罩(外科医生的纸质口罩)呼吸相关的阻力负荷会显著增加呼吸功。对于已有呼吸肌泵负荷过重的患者,面罩导致的额外阻力呼吸可能难以耐受,并会导致吸气肌疲劳。
