USE OF EOS-SPRINT FOR PNEUMOTACHOGRAPHY A ND INDIRECT CALORIMETRY ON SWINE

The EOS sprint system (Jaeger, Wurzburg) was used in pneumotachographi c and indirect calorimetric determination of respiratory and metabolic variables in swine. Investigations were made under defined conditions (without anaesthesia nor sedation but with moderate fixation of proba nds, locomotor rest and after 18 hours of fasting). Two series of meas urements were run under experimental conditions to establish normal va lues of respiratory rate, respiratory minute and tidal volumes, oxygen uptake, carbon dioxide production, quotient of respiration and energy conversion. Results were affected by lenght of testing or habituation of probands as well as by body weight of the pigs involved. These res ults were compared with literature data.
