Hyperoxia,
hypocapnia and hypercapnia as outcome factors after cardiac arrest in children.
The decrease in PC[O.sub.2] and TC[O.sub.2] concentrations after the rest period suggests a process of respiratory alkalosis or
hypocapnia, a phenomenon that has also been observed in hens subjected to caloric stress where the increase in respiration rates leads to a reduction in blood partial pressure of C[O.sub.2] (pC[O.sub.2]) [6, 17, 32].
In contrast to mammals, however,
hypocapnia in birds does not cause a decrease in CBF.
Compensatory
hypocapnia is the expected physiological response to situations of metabolic acidosis, and this response serves to correct acidemia and maintain the blood pH within physiological limits (CARLSON & BRUSS, 2008).
Brain cell swelling during
hypocapnia increases with hyperglycemia or ketosis.
There were no significant differences in the measured physiological parameters between anesthesia groups and the control group, and no incidences of hypoxia, hypercapnia,
hypocapnia, hypotension, hypothermia, or hyperthermia [Table 1].{Table 1}
