Oxygen consumption (VO2) and CO2 production (VCO2) were measured continuously for 24 h in 10 premature infants during their ongoing nursing care. Using a flow-through technique, the total VO2 and VCO2 over a given period of time were determined from the area under the O2-and CO2-concentration-time curve of the mixed expired gas. Following chest physiotherapy, heel stick and i.v. needle insertion, there was a significant (p less than 0.01) increase in VO2 and VCO2. When measured for 24 h, the total daily increase of VO2 attributed to these procedures ranged from 2.1 to 11.7% of total daily VO2, equivalent to an estimated energy loss of 0.6-4.1 kcal/kg/day.
在10名早产儿持续护理期间，连续24小时测量其耗氧量（VO2）和二氧化碳产生量（VCO2）。采用流通技术，根据混合呼出气体的氧气和二氧化碳浓度-时间曲线下的面积，确定给定时间段内的总VO2和VCO2。胸部物理治疗、足跟采血和静脉穿刺后，VO2和VCO2显著增加（p<0.01）。若测量24小时，这些操作导致的VO2每日总增加量占每日总VO2的2.1%至11.7%，相当于估计能量损失0.6-4.1千卡/千克/天。
