Confined spaces in space: Cerebral implications of chronic elevations of inspired carbon dioxide and implications for long‐duration space travel

Experimental Physiology, EarlyView.
Abstract Cerebrovascular regulation is critically dependent upon the arterial partial pressure of carbon dioxide (PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_{\mathrm{2}}}}}$), owing to its effect on cerebral blood flow, tissue PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_{\mathrm{2}}}}}$, tissue proton concentration, cerebral metabolism and cognitive and neuronal ...

Cerebral oxygen extraction across different exercise intensities: Role of arterial PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_2}}}$

Experimental Physiology, EarlyView.
Abstract Stability in cerebral oxygen extraction fraction (OEF) is typically determined by alterations in cerebral blood flow (CBF). At rest, arterial partial pressure of carbon dioxide (PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_2}}}$) and OEF exhibit a strong inverse relationship owing to the powerful influence of PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_2}}}$

Hypercapnea and Acidemia despite Hyperventilation following Endotracheal Intubation in a Case of Unknown Severe Salicylate Poisoning

Case Reports in Critical Care, 2017
Salicylates are common substances for deliberate self-harm. Acute salicylate toxicity is classically associated with an initial respiratory alkalosis, followed by an anion gap metabolic acidosis.

The Basic Principles of Acid-Base Regulation [PDF]

, 1973
In summary, arterial gas studies including pH determinations can be vitally important in the diagnosis and management of patients with a variety of serious medical problems. These studies should be interpreted in the light of clinical and other necessary

Mimicry and well known genetic friends: molecular diagnosis in an Iranian cohort of suspected Bartter syndrome and proposition of an algorithm for clinical differential diagnosis. [PDF]

, 2019
BACKGROUND: Bartter Syndrome is a rare, genetically heterogeneous, mainly autosomal recessively inherited condition characterized by hypochloremic hypokalemic metabolic alkalosis.

Early acclimatization to high altitude: Acid–base and fluid balance dynamics during the first 2 days at 3100 m

Experimental Physiology, EarlyView.
Abstract Immediate responses to hypoxia at high altitude are hyperventilation and successive respiratory alkalosis. Alkalosis, in turn, can affect cerebrospinal fluid pH and ventilatory control. The kidneys compensate metabolically for respiratory alkalosis.

Assessment of Blood pH and pCO2 as Predictors of Febrile Seizures in Paediatric Patients: A Cross-sectional Study [PDF]

Journal of Clinical and Diagnostic Research
Introduction: Febrile seizures commonly occur in the age group of six months to five years. Hypocarbia and alkalosis are known to enhance neuronal excitability and promote epileptiform activity.

Continuous carbon dioxide monitoring in the exhaled breath of mechanically ventilated rats

Experimental Physiology, EarlyView.
Abstract In small animals, carbon dioxide monitoring is either limited by the need to take blood samples for gas analysis, or it interferes with respiratory efficiency and lung mechanics analysis. We introduced a novel approach for continuous monitoring of CO2 in the expiratory limb of the breathing circuit.

Fetal Metabolic Alkalosis Resulting from Maternal Vomiting

American Journal of Perinatology Reports
We describe a pregnant patient with severe compulsive water ingestion and vomiting that lead to metabolic alkalosis and preterm delivery. A 21-year-old patient was hospitalized multiple times throughout pregnancy for symptoms initially thought to be ...
