title: [Acidosis and clinical condition in asphyctic calves].
abstract: In depressed calves (modified APGAR score 4-6) there is at birth an evident combined respiratory-metabolic acidosis (pH = 7.082 +/- 0.175; pCO2 = 73.3 +/- 26.8 mm Hg; BE = -10.6 +/- 7.2 mmol/l). The metabolic adaptation is completed after 6 hours, the respiratory acidosis is present up to 24 hours after delivery. In comparison to normal calves there are significant deviations in pH-values, base excess standard bicarbonate and actual bicarbonate during the whole investigation time. The carbon dioxide tensions of the depressed calves are at birth similar to those of normal calves, but in the following hours they are significantly higher. A definite relationship can be demonstrated between the 1 minute APGAR score and pH-value, base excess, standard bicarbonate and actual bicarbonate. Oxygen tension, oxygen saturation and carbon dioxide do not correlate with the clinical condition.
