一、基础代谢率(BMR) 在维持机体基本的生理活动(血液循环、呼吸及恒定的体温)时,每小时单位体表面积最低耗热量减去标准耗热量,其差值与标准耗热量之百分比,称之为基础代谢率(basal metabolic rate即BMR)。测定BMR是在病人空腹以及尽量避免任何精神和体力的负担下,用基础代谢测量仪检查患者的氧耗量。根据临床用途,则基础代谢率以相当于正常人的耗氧量的百分比表示之。BMR的数值多以正、负百分比表示。正常人的BMR,严格说来应介于+10％至-10％之间。在某些情况下, First, the basal metabolic rate (BMR) in maintaining the body’s basic physiological activity (blood circulation, breathing and constant body temperature), the hourly unit body surface area minus the standard calorie consumption, the difference between the percentage of standard calorific value , Called basal metabolic rate (BMR). Determination of BMR in patients with fasting and try to avoid any mental and physical burden, the use of basic metabolic measuring instrument to check the patient’s oxygen consumption. According to clinical use, the basal metabolic rate is expressed as a percentage of normal human oxygen consumption. BMR values ​​are mostly positive and negative percentage. Normal BMR, strictly speaking, should be between + 10% to -10%. In some cases,
