摘要： An indirect calorimeter for calculating the metabolic rate of a subject by measuring the oxygen consumption during respiration over a period of time includes a gas flow meter (42) providing output electric signals to a microprocessor (20) which drives a display and printer. The output of the flow meter (42) is connected to a mouthpiece (12). The exhaled gas passes through a CO2 scrubber (30) and then through the flow meter (42). The difference in volume between the inhaled gas and the exhaled gas is proportional to the oxygen consumption of the subject and the microprocessor (20) integrates that signal over the time of the test, and multiples it by a constant to provide a metabolic rate display. The temperature and water vapor content of the inhaled air are adjusted to that of the exhaled air either by passing both the inhaled and exhaled gases through the scrubber (30) before their volume is measured, or by preheating the inhaled air and employing a water absorbent member to add moisture to the inhaled air and remove it from the exhaled air.

摘要： A calorimeter for generating signals representative of the oxygen consumption and carbon dioxide production of a subject over a test period (12) includes two flow sensors (48, 64) and a carbon dioxide scrubber (66) connected to a patient mouthpiece (60). Interconnections (44, 46, 52, 54, 56, 58, 62) are such that the air inhaled by the subject passes through one flow meter and the exhaled breath passes first through the other flow meter, the carbon dioxide scrubber and then through the first flow meter. The electrical output signals from the flow meters are provided to a microprocessor based computer (50) which integrates the volume differences between the inhaled gas, and the exhaled gas after the carbon dioxide has been removed from it, over the period of the test.

摘要： An indirect calorimeter for measuring the metabolic activity and related respiratory parameters of a subject includes a facial mask (14) operative to be supported in contact with the subject so as to pass the inhalations and exhalations as the patient breathes. Both the inhaled and exhaled gasses pass through a tube (16) which incorporates an ultrasonic pulse transit time flow meter (64, 70) adapted to generate electrical signals as a function of the instantaneous flow volume. A fluorescence quench oxygen sensor (82) is supported in the flow tube (16) and generates electrical signals as a function of the instantaneous oxygen content of the respiratory gasses. A computation unit (76) receives output signals from the flow sensor (64, 70) and the oxygen sensor (82) to calculate oxygen consumption, and related parameters.

摘要： An indirect calorimeter for measuring the subject's oxygen consumption per unit of time employs a mouthpiece (12) through which the subject breathes for a period of time. Conduits connect the mouthpiece to a flow meter (14) and a capnometer (26) so that the subject's inhalations, and exhalations pass through the flow meter, and the exhalations also pass through the capnometer. Electrical signals from the flow meter and capnometer are provided to a computer (22) which calculates the CO2 exhaled by the subject during the test by integrating the instantaneous CO2 content of an exhalation as measured by the capnometer over the volume as measured by the flow meter, substracts that quantity from the exhaled volume, and substrats their difference from the inhaled volume. In alternative embodiments the system can also measure the subject's cardiac output and delivered oxygen.

摘要： Calorimètre indirect destiné à calculer le rythme métabolique d'un sujet en mesurant la consommation d'oxygène pendant la respiration sur un laps de temps donné, comprenant un dispositif (42) de mesure du débit de gaz fournissant des signaux électriques de sortie à un microprocesseur (20) qui commande un écran d'affichage et une imprimante. La sortie du dispositif (42) de mesure du débit est reliée à un embout buccal (12). Le gaz expiré passe à travers un épurateur de CO2 (30) et ensuite à travers le dispositif (42) de mesure du débit. La différence de volume entre le gaz inspiré et le gaz expiré est proportionnelle à la consommation d'oxygène du sujet et le microprocesseur (20) intègre ce signal pendant la durée du test, puis le multiple par une constante pour donner un affichage du rythme métabolique. La température et la teneur en vapeur d'eau de l'air inspiré sont ajustées à celles de l'air expiré soit en faisant passer à la fois les gaz expirés et inspirés à travers l'épurateur (30) avant de mesurer leur volume, soit en préchauffant l'air inspiré et en employant un élément absorbant l'eau pour ajouter de l'humidité à l'air inspiré et prélever l'humidité de l'air expiré.
