The elimination of Xe133 from a deposit in the subcutaneous adipose tissue outside the anterior tibial muscle was recorded by an external scintillation detector in 16 human subjects during normal breathing, negative-pressure breathing (-20 cm H2o), and positive-pressure breathing (+20 cm H2O). The ambient temperature was kept at 28.0 degrees C +/- 0.1 degrees, which can be considered a neutral temperature. The xenon clearance rate was increased during negative-pressure breathing by a mean of 68% and decreased during positive-pressure breathing by a mean of 73% when compared to normal breathing. The xenon-elimination rates during the different conditions may reflect corresponding changes in adipose-tissue blood flow. Because both negative- and positive-pressure breathing may occur during diving, the uptake and elimination of inert gases in adipose tissue of a diver may be influenced; thus, the risk of decompression sickness might also be affected. The results may therefore be of importance in diving routines and in the construction of breathing apparatus for divers.
通过外部闪烁探测器记录了16名人类受试者在正常呼吸、负压呼吸（-20 cm H₂O）和正压呼吸（+20 cm H₂O）过程中，¹³³Xe从前胫骨肌外侧皮下脂肪组织沉积物中的消除情况。环境温度保持在28.0℃±0.1℃，这可视为中性温度。与正常呼吸相比，负压呼吸期间氙清除率平均提高了68%，正压呼吸期间平均降低了73%。不同条件下的氙消除率可能反映了脂肪组织血流的相应变化。由于潜水过程中可能会出现负压和正压呼吸，潜水员脂肪组织中惰性气体的摄取和消除可能会受到影响；因此，减压病的风险也可能受到影响。因此，这些结果可能对潜水常规操作以及潜水员呼吸设备的构建具有重要意义。
