为了提高对低氧血症状态的分析和动脉血供氧能力的判断，对４０例出生后１ｈ至１５ｄ住院的新生儿肺炎病人的血气分析数据进行了深入图像分析．均采取股动脉或桡动脉血，检测用丹麦产ＡＢＬ６２０型血气分析仪，试剂及计算机软件全部由丹麦雷度公司提供．４０例中，ＣｔＯ２（动脉血氧含量）下降２９例（７２．５％），ＳＯ２（血氧饱和度）下降２０例（５０．０％），ｐＯ２ａ（动脉血氧分压）下降２５例（６２．５％）．在ｐＯ２ａ正常的１５例中经深入图像分析有８例Ｐｘ（氧张力）均低于正常，这表明低血氧症的实际例数应为３３例，占总数的８２．５％．４０例中ｃｔＨｂ（总血红蛋白）下降１９例（４７．５％），ｃｅＨｂ（有效血红蛋白）下降２２例（５５．０％），Ｏ２Ｈｂ（氧合血红蛋白）正常仅１１例（２７．５％）．４０例中３５例（８７．５％）Ｐ５０下降，氧离曲线左移，表明血红蛋白释氧能力下降，３３例（８２．５％）Ｐｘ低于正常，表明有动脉血释氧能力下降，在临床上需要给氧．
In order to improve the analysis of hypoxemia status and judgment of arterial blood oxygen supply, in-depth image analysis was performed on the blood gas analysis data of 40 neonates with pneumonia admitted in hospital from 1 hour to 15 days after birth. Both take femoral artery or radial artery blood test, the test with the Danish ABL620 blood gas analyzer, reagents and computer software all provided by Danish company. Among the 40 cases, 29 cases (72.5%) decreased CtO2 (arterial oxygen content), 20 cases (50.0%) decreased SO2 (oxygen saturation) and 25 cases decreased pO2a 62.5%). In 15 cases with normal pO2a, 8 cases of Px (oxygen tension) were below normal by deep image analysis, indicating that the actual number of hypoxemia cases should be 33 cases, accounting for 82.5% of the total. Of the 40 patients, 19 (47.5%) had a decrease in ctHb (total hemoglobin), 22 (55.0%) had a decrease in ceHb (effective hemoglobin) and only 11 (27.5%) had normal O2Hb. In 40 cases, P50 decreased in 35 cases (87.5%) and shifted to the left. This indicated that hemoglobin release capacity decreased, and Px in 33 cases (82.5%) was lower than normal, indicating that arterial oxygen release decreased Clinically need oxygen.
