Antral secretions from patients with maxillary sinusitis were aspirated for determination of pO2, pCO2 and pH. In 14 non-purulent secretions the mean pO2 was 12.7 kPa (96 mmHg) and the mean pCO2 5.2 kPa (39 mmHg). The mean pH was slightly alkaline. In 18 purulent secretions, usually with a heavy growth of pneumococci or H. influenzae, the pO2 was zero or close to zero and the mean pCO2 greater than or equal to 10.1 kPa (greater than or equal to 76 mmHg). The mean pH was slightly acid and significantly lower than in the nonpurulent secretions. The gas composition and the pH in purulent secretions do not only influence the metabolic activity and multiplication of bacteria, but may also interfere with the local protective functions of the sinus mucosa and with the bactericidal function of granulocytes.
对上颌窦炎患者的窦腔分泌物进行抽吸，以测定氧分压（pO2）、二氧化碳分压（pCO2）和pH值。在14份非脓性分泌物中，平均pO2为12.7千帕（96毫米汞柱），平均pCO2为5.2千帕（39毫米汞柱）。平均pH值呈轻度碱性。在18份脓性分泌物中，通常肺炎球菌或流感嗜血杆菌大量生长，pO2为零或接近零，平均pCO2大于或等于10.1千帕（大于或等于76毫米汞柱）。平均pH值呈轻度酸性，且显著低于非脓性分泌物。脓性分泌物中的气体成分和pH值不仅会影响细菌的代谢活性和繁殖，还可能干扰窦黏膜的局部保护功能以及粒细胞的杀菌功能。
