Acute Hypercapnia/Ischemia Alters the Esterification of Arachidonic Acid and Docosahexaenoic Acid Epoxide Metabolites in Rat Brain Neutral Lipids. [PDF]

, 2020
In the brain, approximately 90% of oxylipins are esterified to lipids. However, the significance of this esterification process is not known. In the present study, we (1) validated an aminopropyl solid phase extraction (SPE) method for separating ...

Effect of mild hypercapnia during the recovery period on the emergence time from total intravenous anesthesia: a randomized controlled trial [PDF]

Korean Journal of Anesthesiology
Background Intraoperative hypercapnia reduces the time to emergence from volatile anesthetics, but few clinical studies have explored the effect of hypercapnia on the emergence time from intravenous (IV) anesthesia. We investigated the effect of inducing

New insights in gill/buccal rhythm spiking activity and CO2 sensitivity in pre- and post-metamorphic tadpoles (Pelophylax ridibundus)

, 2013
Central CO2chemosensitivity is crucial for all air-breathing vertebrates and raises the question of itsrole in ventilatory rhythmogenesis. In this study, neurograms of ventilatory motor outputs recorded infacial nerve of premetamorphic and ...

Adaptation of Respiratory-Related Brain Regions to Long-Term Hypercapnia: Focus on Neuropeptides in the RTN

Frontiers in Neuroscience, 2019
Long-term hypercapnia is associated with respiratory conditions including obstructive sleep apnea, chronic obstructive pulmonary disease and obesity hypoventilation syndrome.

Hypercapnia in COPD: Causes, Consequences, and Therapy

Journal of Clinical Medicine, 2022
Chronic obstructive pulmonary disease (COPD) is a progressive respiratory disorder that may lead to gas exchange abnormalities, including hypercapnia. Chronic hypercapnia is an independent risk factor of mortality in COPD, leading to epithelial dysfunction and impaired lung immunity.

Optimization techniques in respiratory control system models [PDF]

, 2016
One of the most complex physiological systems whose modeling is still an open study is the respiratory control system where different models have been proposed based on the criterion of minimizing the work of breathing (WOB).

A retrospective study of the role of hypercapnia in patients with acromegaly

BMC Pulmonary Medicine, 2023
Background Acromegaly is a multisystemic disease characterized by an excessive release of growth hormone (GH) and insulin-like growth factor-1. Obstructive sleep apnea (OSA) is a common consequence of acromegaly, and hypercapnia is frequently observed in

Lung-Protective Ventilation Attenuates Mechanical Injury While Hypercapnia Attenuates Biological Injury in a Rat Model of Ventilator-Associated Lung Injury

Frontiers in Physiology, 2022
Background and Objective: Lung-protective mechanical ventilation is known to attenuate ventilator-associated lung injury (VALI), but often at the expense of hypoventilation and hypercapnia.

Detection of impaired cerebral autoregulation improves by increasing arterial blood pressure variability

, 2012
Although the assessment of dynamic cerebral autoregulation (CA) based on measurements of spontaneous fluctuations in arterial blood pressure (ABP) and cerebral blood flow (CBF) is a convenient and much used method, there remains uncertainty about its ...

THE FOOTPRINT OF HYPERCAPNIA ON INFLAMMATORY PATHWAYS DURING BACTERIAL INFECTION

Open Respiratory Archives
Introduction: Pneumonia frequently occurs under hypercapnic conditions. Previous studies in hypercapnic models have reported that elevated CO2 levels inhibit the NF-κB pathway, resulting in reduced inflammation.
