The total gas pressure in experimentally occluded maxillary sinus was continuously recorded during 90 minutes on 7 healthy human subjects. PO2 and PCO2 were measured before and after the total pressure recording. In 3 cases the volume changes in the sinus were measured. The total gas pressure after an initial increase to about 35 mm H2O decreased to a steady state of about 70 mm H2O below atmospheric pressure. The volume changes in sinus showed a corresponding alteration. The gas measurements showed a decrease of PO2 of 25 mm Hg and a rise of PCO2 of 21 mm Hg. In 3 patients with acute purulent sinusitis there was seen a pressure of about 10 cm H2O above the atmospheric pressure.
在7名健康人体受试者身上，对实验性阻塞的上颌窦内的总气压进行了90分钟的连续记录。在记录总气压之前和之后测量了氧分压（PO2）和二氧化碳分压（PCO2）。对3例受试者测量了窦内的容积变化。总气压在最初升高至约35毫米水柱后，降至低于大气压约70毫米水柱的稳定状态。窦内的容积变化呈现出相应的改变。气体测量结果显示氧分压降低了25毫米汞柱，二氧化碳分压升高了21毫米汞柱。在3例急性化脓性鼻窦炎患者中，观察到气压比大气压高约10厘米水柱。
