BACKGROUND & AIMS: During the coronavirus disease 2019 (COVID-19) pandemic the use of Indirect calorimetry (IC) during nutritional rehabilitation program requires special precautions due to possible contagions for patients and health professionals. We evaluated in a sample of healthy subjects the agreement between oxygen consumption (VO mL/min), carbon dioxide production (VCO mL/min), respiratory quotient (RQ) and resting energy expenditure (REE kcal/24 h/day) measured by IC with and without a filtering facepiece mask.
MATERIALS
10 subjects with a mean (SD) age of 43 (10) years and a body mass index of 25.2 (5.8) kg/m underwent indirect calorimetry both with and without a class 2 filtering facepiece mask (FFP2), in random order. The limits of agreement (LOA) and the concordance correlation coefficient (CCC) were used to evaluate the interchangeability of the measurement conditions.
RESULTS
The LOA between REE measured with and without FFP2 (-111 to 189 kcal/day) were comparable to those for repeated IC tests without wearing masks and CCC (0.95) showed substantial agreement.
CONCLUSIONS
We observed high agreement between REE measured by IC with and without FFP2 mask. These procedures are interchangeable in clinical practice.
背景与目的
在 2019 年冠状病毒病（COVID-19）大流行期间，由于患者和卫生专业人员可能受到感染，营养康复计划中使用间接热量测定法（IC）需要特别注意。我们在一组健康受试者中评估了在使用和不使用过滤面罩的情况下，通过 IC 测量的耗氧量（VO mL/min）、二氧化碳产生量（VCO mL/min）、呼吸商（RQ）和静息能量消耗（REE kcal/24 h/天）之间的一致性。
材料
10 名年龄（SD）为 43（10）岁，体重指数（BMI）为 25.2（5.8）kg/m2的受试者分别以随机顺序接受了有无 2 级过滤式面罩（FFP2）的间接热量测定。使用限差（LOA）和一致性相关系数（CCC）评估了两种测量条件的可互换性。
结果
在有无 FFP2 情况下测量的 REE 的 LOA（-111 至 189 kcal/天）与不戴口罩进行重复 IC 测试的 LOA 相当，CCC（0.95）显示出高度一致性。
结论
我们观察到在有无 FFP2 口罩的情况下，通过 IC 测量的 REE 之间具有高度一致性。这些程序在临床实践中可以互换。
