Apr 12, 2016 · 鉴于 VCO 2 在很多呼吸机上能被测量,这不失为一种计算 EE 简单易行的方法。 改良的 Weir方程与预测方程相比具有更好的精确度:REE, kcal/day = 5.5 × VCO 2 (L/min) × 1440(以固定为 0.89 的呼吸商计)。 但是,固定的呼吸商造成了不准确的延续。
当受试者摄入一定量的双标水后, ^ {2}H 反应在体内水的代谢, ^ {18}O 既反应在体内水的代谢,也反应在 CO_ {2} 的代谢,当 H_ {2}O 和 CO_ {2} 反应平衡时,计算的 CO_ {2} 生成率、 O_ {2} 的消耗率和呼吸商(Respiratory Quotient,RQ),利用Weir 公式计算实验时间内的人体总 ...
In 1949 Weir (3) demonstrated that the metabolic rate calculated from respiratory gas exchange measurements is to a close approximation proportional to the difference in percentage oxygen content between inspired and ...
通过呼吸商 (Res p irat ory Quotient, RQ)和得到的 CO2生成率可算出 O2 消耗量 ,最后利用经典的 Weir公式 [ 6 ]就能计算出单位时间内平均能量的消耗量。
The formula that is used to calculate the Resting Energy Expenditure (REE) in the LabChart Metabolic Module is as follows: REE = 16.318VO2 + 4.602VCO2 This is an adaptation of the abbreviated Weir Equation which state...
Feb 9, 2018 · 该公式为目前最为公认的推算基础代谢的公式(WHO推荐),有研究表明与本文中的公式1、2、4、7、9相比,其更适合于预测我国健康成年人的基础代谢(梁洁等,2008),且用于预测中国女性个体和北方个体基础代谢误差更小(李可基,2004)。
The Weir Equation Calculator helps calculate water flow rates through weirs, aiding in efficient water management and engineering projects.
The weir coefficient is a dimensionless parameter that incorporates the gravitational acceleration, discharge coefficient, and the geometric characteristics of the weir into a single value.
是19.62千焦耳(4.69千卡) :也就是使用一公升氧氣氧化脂肪的反應所產生的熱量。 其所得結果在呼吸商=1時(僅燃燒醣類)與威耳公式相同,在呼吸商=0.7時(僅燃燒脂肪)幾乎與威耳公式相同。
