Combined Research Techniques

Integrate study techniques and tools to unlock new opportunities in your research 



DSI solutions are used in combination with many other technologies for various research applications in both small and large animal models. The benefits of holistic research includes a greater chance of study approval and funding, a decrease in the number of animals used, the ability to identify physiological changes from multiple organ systems, and overall better science.

METABOLISM AND TELEMETRY

Indirect calorimetry is the estimation of metabolic heat production by an organism from measurement of indices such as oxygen consumption or carbon dioxide production. For the purpose of most energy-expenditure studies, indirect calorimetry measures the volume of expired air per unit of time and determines the percentage of oxygen utilized. These data are then used for estimating the metabolic rate (energy expenditure) and respiratory exchange ratio (relative measurement of fat, carbohydrate and protein oxidation). Indirect calorimetry systems contain air tight chambers, so measuring physiological endpoints during indirect calorimetry testing is difficult. Our Panlab Oxylet Pro systems have all been tested and validated to properly work in combination with DSI implantable telemetry, allowing for the acquisition of meaningful and high impact holistic in vivo data. 

Common endpoints achieved through the use of telemetry include ECG, blood pressure, continuous blood glucose, temperature, activity, and more.
