title: Blood gas analysis and cooximetry in retired racing Greyhounds.
abstract: OBJECTIVE
  The purposes of this study were to evaluate the oxygen affinity of hemoglobin (Hb) in healthy retired racing Greyhounds via cooximetry, and to establish reference intervals for blood gases and cooximetry in this breed.
  
  
  METHODS
  Prospective clinical study.
  
  
  METHODS
  University Teaching Hospital.
  
  
  METHODS
  Fifty-seven Greyhounds and 30 non-Greyhound dogs.
  
  
  METHODS
  Venous blood samples were collected from the jugular vein and placed into heparinized tubes. The samples were analyzed within 30 minutes of collection using a blood gas analyzer equipped with a cooximeter.
  
  
  RESULTS
  Greyhounds had significantly higher pH, PO(2) , oxygen saturation, oxyhemoglobin, total Hb, oxygen content, and oxygen capacity and significantly lower deoxyhemoglobin and P(50) when compared with non-Greyhound dogs.
  
  
  CONCLUSIONS
  These findings support the fact that this breed is able to carry a higher concentration of total oxygen in the blood. As reported previously, this breed also has lower P(50) and, therefore, high oxygen affinity. In light of recent findings suggesting that in certain tissues a high affinity for oxygen is beneficial, this adaptation may be of benefit during strenuous exercise.
