LRH100 Respiratory Heat Metabolism Tester

Description

LRH100 Respiratory Heat Metabolism Tester

Feature：

Respiratory heat metabolism tester(referred to as nutrient metabolism vehicle) can detect the amount of carbon dioxide exhaled by the human body and the amount of oxygen inhaled in real time, accurately calculate the respiratory quotient and basic metabolic rate, analyze the composition of the three major nutrients (carbohydrates, fats and proteins) in the energy supply, and evaluate the metabolic balance of the human body, which has a wide range of applications in clinical medicine and public health. In clinical practice, correct nutritional support mode is provided through metabolic detection to provide scientific and effective data support for patients’ treatment and rehabilitation. In the field of public health, the deficiency or excess of major nutrients in the human body can be determined through the detection of nutritional metabolism, and personalized exercise and nutrition programs can be used to intervene, and finally achieve the balance of the three nutrients, which can prevent obesity, malnutrition, hyperlipidemia, fatty liver, diabetes and other metabolic diseases.

Characteristics and advantages：

*Fast:Wearing a hood and breathing for 10-20 minutes can obtain energy metabolism data in the human body.
*Science:Indirect calorimetry is the “gold standard” for energy consumption measurement.
*Comprehensive:The energy metabolism rate and energy substrate consumption in vivo were evaluated comprehensively.
*Comfort:Open measurement, free breathing air during testing.
*Expediency:Automatic calibration, full Chinese human-computer interface, visual chart display.

Demonstration application:

Nutritional metabolism detector in Xinjiang Autonomous Region People’s Hospital, the General Hospital of the People’s
Liberation Army and other three hospitals to carry out clinical trials, for clinical patients nutritional dietary support to provide a powerful tool, highly recognized by patients and clinicians, in addition to a number of high-end weight loss clubs, fitness institutions and chronic disease management institutions are interested in introducing this product.
