用于防止职业性有毒暴露的呼吸器（呼吸个人防护装置）可能会施加流动阻力和死区呼吸负荷。在10名健康志愿者中测定了运动水平、300 ml死亡空间和单个呼吸器吸入负荷的影响。受试者倾向于限制峰值工作速率（产生的压力和压力次数）。流)和延长呼吸周期的吸气部分，由于呼吸的使用。氧气消耗和心率无明显影响。定性反应不受运动水平的影响。在亚极限运动中，正常受试者未达到所研究变量的补偿极限。
Respirators (respiratory personal protective devices), used for protection against occupational toxic exposures, may impose flow resistance and dead space respiratory loading. Effects of exercise level, a 300 ml deadspace and single respirator cartridge inspiratory load were determined in 10 healthy volunteers. Subjects tended to limit peak work rate (pressure generated and pressure .times. flow) and to prolong the inspiratory portion of the respiratory cycle due to respiratory use. O2 consumption and heart rate were not significantly affected. The qualitative response was not affected by exercise level. During submaximal exercise, normal subjects did not reach their compensation limits for the variables studied.
