新生儿1天后血气分析的样本正常值范围,并依此推算出总体的正常值范围。新生儿血气分析的正常值范围为:pH:7.251～7.429,PCO_2 2.806～7.235kPa(2 1.1～54.4mmHg),PO_25.320～7.940kPa(40.0～59.7mmHg),BE_(ECF)一7.5～5....5mmol/L,BE—7.5～4.5mmol/L,BB38.3～52.4mmol/L,HCO_317～29mmol/L,TCO_215～31mmol/L,O_2ST0.79～0.96,O_2CT0.18～0.27vol。据此建议用足跟动脉化血PO_25.32kPa(40mmHg),PCO_27.315kPa(55mmHg)作为呼吸衰竭的诊断标准。
