Assessing cerebrovascular reactivity by the pattern of response to progressive hypercapnia

Sign Up to like & get
recommendations! Published in 2017 at "Human Brain Mapping"

DOI: 10.1002/hbm.23598

Abstract: Cerebral blood flow responds to a carbon dioxide challenge, and is often assessed as cerebrovascular reactivity, assuming a linear response over a limited stimulus range or a sigmoidal response over a wider range. However, these… read more here.

recommendations! Published in 2022 at "Pediatric Pulmonology"

DOI: 10.1002/ppul.26108

Abstract: In adults, permissive hypercapnia reduces mortality and ventilation duration. However, in preterm infants, the findings from past research regarding the efficacy and safety of permissive hypercapnia are controversial. read more here.

DOI: 10.1007/s00134-022-06696-z

Abstract: We read with great interest the systematic review and meta-analysis by Gendreau and colleagues [1] examining the relation between hypercapnia and mortality in patients affected by acute respiratory distress syndrome (ARDS). We would like, however,… read more here.

DOI: 10.1016/j.cbpa.2020.110672

Abstract: Fossorial giant Zambian mole-rats are believed to live in a hypoxic and hypercapnic subterranean environment but their physiological responses to these challenges are entirely unknown. To investigate this, we exposed awake and freely-behaving animals to… read more here.

DOI: 10.1016/j.ebiom.2019.03.029

Abstract: Background It is increasingly evident that perturbations to the diversity and composition of the gut microbiota have significant consequences for the regulation of integrative physiological systems. There is growing interest in the potential contribution of… read more here.

DOI: 10.1016/j.envres.2017.10.035

Abstract: ABSTRACT Environmental hypercapnia in shallow coastal marine ecosystems can be exacerbated by increasing levels of atmospheric CO2. In these ecosystems organisms are expected to become increasingly subjected to pCO2 levels several times higher than those… read more here.

DOI: 10.1016/j.margen.2019.01.007

Abstract: Transcriptional regulation constitutes a rapid response of marine organisms facing stressful environmental conditions, such as the concomitant exposure to warming, ocean acidification and hypoxia under climate change. In previous studies, we investigated whole-organism physiological patterns… read more here.

Lesion of Serotonergic Afferents to the Retrotrapezoid Nucleus Impairs the Tachypneic Response to Hypercapnia in Unanesthetized Animals

recommendations! Published in 2021 at "Neuroscience"

DOI: 10.1016/j.neuroscience.2020.11.005

Abstract: Hypercapnia promotes an increase in pulmonary ventilation due to the stimulation of brainstem chemosensory cells that are connected to the respiratory network. Among these cells are the raphe serotonergic neurons which widely send projections to… read more here.

recommendations! Published in 2017 at "Neuromuscular Disorders"

DOI: 10.1016/j.nmd.2016.12.006

Abstract: In neuromuscular disease (NMD) patients, current guidelines recommend the initiation of home mechanical ventilation (HMV) in case of daytime hypercapnia or nocturnal desaturation as an indirect sign of hypoventilation. Transcutaneous capno-oximetry (TcCO2) enables the direct… read more here.

DOI: 10.1093/eurheartj/ehae666.1774

Abstract: The Targeted Therapeutic Mild Hypercapnia After Resuscitated Cardiac Arrest (TAME) trial found similar neurological outcomes between mild hypercapnia and normocapnia in resuscitated out-of- hospital cardiac arrest (OHCA) patients. Hypercapnic acidosis can cause pulmonary vasoconstriction and… read more here.

DOI: 10.1093/sleep/zsad077.0901

Abstract: Congenital central hypoventilation syndrome (CCHS) is a rare disorder of respiratory deficiency due to a mutation in the PHOX2B gene. Clinical presentation may be mild in certain individuals due to different levels of ventilatory dysregulation.… read more here.
