Respiratory alkalosis and primary hypocapnia
in Labrador retrievers participating in field trials in high-ambient-temperature conditions.
Role of cerebrospinal fluid pH in normalization of flow in chronic hypocapnia
23,24) In some cases, the abrupt opening of the upper airway because of a micro-arousal causes hyperventilation with subsequent hypocapnia
, leading to a reduction in PDM activity and a greater collapse of the upper airway.
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.
In contrast to mammals, however, hypocapnia
in birds does not cause a decrease in CBF.
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.
5) In addition, poor blood flow to the affected lung may result in alveolar hypocapnia
, leading to secondary bronchoconstriction and mucous trapping.
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].
Adult SBIFs in the first 24 hours (2003) Severe TBI postinjury: hypotension, Transport time < 2 hours hypoxia, hypercapnia, to level I trauma center hypocapnia
, HT, fever, metabolic acidosis, seizures, coagulopathy, hyperglycemia, and IICP SBIF was recorded during six periods: hours 1, 2, 3, 4, 5-14, and 16-24 Occurrence of each SBIF then correlated with outcome Author Outcomes Main Findings Thompson, Discharge and HT on admission correlated with: Kirkness, 6-month COS-E --Longer LOS (r = .
Nontraumatic causes of T-LOC include syncope, epileptic seizures, intoxication, vertebrobasilar transient ischaemic attack (TIA) and metabolic disorders, such as hypoglycaemia, hypoxia and hyperventilation with hypocapnia
Cerebral hemodynamic changes during sustained hypocapnia
in severe head injury: can hyperventilation cause cerebral ischemia?
