Summary

Correcting blood gas measurements to rectal temperature (Tre) can lead to errors in analyzing exercising mammals. This method may inaccurately suggest more severe hypoxemia and mask hypercapnia, impacting exercise physiology research.

Area of Science:

  • Exercise Physiology
  • Comparative Physiology
  • Mammalian Physiology

Background:

  • Accurate blood gas analysis is crucial for understanding physiological responses during exercise.
  • Body temperature varies across different compartments during physical exertion.
  • Standard blood gas correction methods may not fully account for transient temperature changes.

Purpose of the Study:

  • To evaluate the accuracy of blood gas measurements corrected to rectal temperature (Tre) versus core temperatures during exercise.
  • To determine if correcting to Tre introduces significant errors in blood gas analysis of exercising mammals.
  • To assess the impact of temperature discrepancies on the interpretation of hypoxemia and hypercapnia.

Main Methods:

  • Horses and steers were exercised on a treadmill to maximal oxygen consumption (VO2max).

  • Temperatures were measured in pulmonary artery (Tpa), intramuscular (Tm), and rectum (Tre).
  • Blood gas samples were analyzed and corrected to different temperature references.

    • Main Results:

    • Pulmonary arterial temperature (Tpa) increased faster than rectal temperature (Tre) during exercise.
    • Intramuscular temperature (Tm) rose faster than Tpa and decreased slower than Tpa post-exercise.
    • Correcting blood gases to Tre without considering Tpa and Tm led to biased results, overestimating hypoxemia and underestimating hypercapnia in horses.

    Conclusions:

    • Using rectal temperature (Tre) for blood gas correction during exercise can introduce significant analytical errors.
    • These errors can lead to misinterpretations of oxygenation and carbon dioxide status at maximal exercise.
    • Accurate temperature measurement and correction are vital for reliable blood gas analysis in exercising animals.
