The role of hypercapnia in acute respiratory failure

Intensive Care Medicine Experimental, 2019
The biological effects and physiological consequences of hypercapnia are increasingly understood. The literature on hypercapnia is confusing, and at times contradictory.

Effects of Acute Systemic Hypoxia and Hypercapnia on Brain Damage in a Rat Model of Hypoxia-Ischemia. [PDF]

PLoS ONE, 2016
Therapeutic hypercapnia has the potential for neuroprotection after global cerebral ischemia. Here we further investigated the effects of different degrees of acute systemic hypoxia in combination with hypercapnia on brain damage in a rat model of ...

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).

Hypercapnia as a preventative therapeutic strategy: Unveiling the neuroprotective potential and mechanisms

Brain Disorders
Hypercapnia, an increase in carbon dioxide (CO2) in the bloodstream, has been historically considered purely a pathological condition. However, based on several publications evaluating the adverse outcome of certain conditions with an additional ...

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

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.

Interactions of chemostimuli at the single cell level: studies in a model system [PDF]

, 2004
The responses of afferent chemosensory fibres of the carotid body to individual chemostimuli have long been established. However, the mechanisms underlying the multiplicative interactions of these stimuli (i.e.
