Sub-cortical and brainstem sites associated with chemo-stimulated increases in ventilation in humans [PDF]
, 2010 We investigated the neural basis for spontaneous chemo-stimulated increases in ventilation in awake, healthy humans. Blood oxygen level dependent (BOLD) functional MRI was performed in nine healthy subjects using T2weighted echo planar imaging.

THE FOOTPRINT OF HYPERCAPNIA ON INFLAMMATORY PATHWAYS DURING BACTERIAL INFECTION
Open Respiratory ArchivesIntroduction: 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.

Hypercapnia: An Aggravating Factor in Asthma
, 2020 Asthma is a common chronic respiratory disorder with relatively good outcomes in the majority of patients with appropriate maintenance therapy. However, in a small minority, patients can experience severe asthma with respiratory failure and hypercapnia ...

Biventricular Pressure‐Volume Loop Analysis in an LVAD Patient Optimized With Impella RP Flex
Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT Right ventricular (RV) failure after left ventricular assist device (LVAD) implantation is a serious complication which may necessitate temporary mechanical support in refractory cases. Here we describe a 63‐year‐old man with end‐stage ischemic cardiomyopathy and severe combined pre‐ and post‐capillary pulmonary hypertension who developed ...

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

Chronic hypercapnia inhibits hypoxic pulmonary vascular remodeling
, 2000 Chronic hypercapnia is commonly found in patients with severe hypoxic lung disease and is associated with a greater elevation of pulmonary arterial pressure than that due to hypoxia alone.
