Respirometers measure the amount of oxygen we inhale and exhale. They measure the amount of carbon dioxide in our exhaled breath. Like the carbon dioxide concentration, the amount of oxygen we need to breathe is referred to as the arterial oxygen saturation or SaO2.

WebRespirometry is a general term that encompasses a number of techniques for obtaining estimates of the rates of metabolism of vertebrates, invertebrates, plants, tissues, cells, or microorganisms via an indirect measure of heat production ( calorimetry ). WebThe instrument called a respirometer, does this. Sodium hydroxide absorbs all CO 2 from the air in the apparatus from the beginning. Potassium hydroxide could be used instead of sodium hydroxide. They both absorb CO 2. As the germinating seeds use oxygen and the pressure reduces in tube A so the manometer level nearest to the seeds rises.
