Deep-Sea Respirometry: In Situ Techniques
1983The deep-sea environment occupies over half the earth’s surface. However, inaccessibility has greatly restricted the study of this unique environment characterized by high pressure and low temperature. Technological advances over the past 15 years permit us to “enter” the deep-sea environment either directly with submersibles or indirectly with ...

Flow-through Respirometry: The Basics
2018This chapter describes the basic theory behind the most widely used method for measuring metabolic rates: flow-through or open-system respirometry. The advantages and disadvantages of the technique are summarized and the two major types of flow-through respirometry systems are described. Recommendations are given on choosing an appropriate flow rate to

Open-circuit respirometry: real-time, laboratory-based systems
European Journal of Applied Physiology, 2018This review explores the conceptual and technological factors integral to the development of laboratory-based, automated real-time open-circuit mixing-chamber and breath-by-breath (B × B) gas-exchange systems, together with considerations of assumptions and limitations.

Room Calorimetry and Mask Respirometry
2018This chapter describes two approaches to human metabolic measurement: room calorimetry and dilution mode mask (or hood, or canopy) respirometry. For room calorimetry, where the EE of a subject is typically monitored for 24 h, strategies for arranging air flow systems and the convective air movement required for effective time constant compensation are ...

[Examination of liver mitochondria with respirometry].
Magyar sebeszet, 2017Due to their diverse physiological functions, mitochondria can cause various acute and chronic liver diseases, thus being potential targets for therapies and diagnostics as well. In this study, the advantages of high-resolution respirometry are presented for the assessment of liver mitochondrial functions.

Constant Volume and Constant Pressure Respirometry
2008This chapter describes constant pressure (Gilson) and constant volume (Warburg) respirometry—long-established techniques that are still capable of accurate results. These are useful for measuring the metabolic rates of small organisms, cell cultures, and biochemical preparations.

High-Resolution Respirometry in a Small-Volume Chamber
Journal of Visualized ExperimentsInvestigating respiratory fluxes is decisive for understanding the complex interplay between metabolic processes. Studies of cells and tissues with limited sample availability and low respiratory rates may benefit from small experimental volumes. We examined if the 0.5 mL chamber yields results consistent with the 2.0 mL chamber at identical sample ...
