Latent class growth analysis of dynamic PaCo2 patterns and clinical outcomes in acute brain injury [PDF]
Scientific ReportsTo analyze dynamic patterns of arterial carbon dioxide partial pressure (PaCO₂) using latent class growth analysis in acute brain injury patients and investigate their associations with 28-day ICU mortality and 60-day in-hospital mortality.

Control of Cerebral Blood Flow by Blood Gases
Frontiers in Physiology, 2021 Cerebrovascular reactivity can be measured as the cerebrovascular flow response to a hypercapnic challenge. The many faceted responses of cerebral blood flow to combinations of blood gas challenges are mediated by its vasculature’s smooth muscle and can ...

Hyperventilation in Adult TBI Patients: How to Approach It?
Frontiers in Neurology, 2021 Hyperventilation is a commonly used therapy to treat intracranial hypertension (ICTH) in traumatic brain injury patients (TBI). Hyperventilation promotes hypocapnia, which causes vasoconstriction in the cerebral arterioles and thus reduces cerebral blood

Natural high ambient temperature-induced respiratory hypocapnia without activation of the hypothalamic-pituitary-adrenal axis in lactating goats [PDF]
Veterinary World, 2022 Background and Aim: Activation of breathing, the hypothalamic-pituitary-adrenal (HPA) axis, and plasma antioxidant defense are adaptive mechanisms in lactating dairy goats fed during the summer season.

The Effects of Hypocapnia on Brain Tissue Pulsations
Brain Sciences, 2020 Hypocapnia is known to affect patients with acute stroke and plays a key role in governing cerebral autoregulation. However, the impact of hypocapnia on brain tissue pulsations (BTPs) is relatively unexplored.

Physiological assessment of orthostatic intolerance in chronic fatigue syndrome
Journal of Translational Medicine, 2022 Background Orthostatic intolerance-OI is common in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome-ME/CFS. We used a 10-min passive vertical lean test as orthostatic challenge-OC and measured changes in vitals and end tidal CO2 (eTCO2).

Hypocapnia is an independent predictor of in‐hospital mortality in acute heart failure
ESC Heart Failure, 2023 Aims Acute heart failure (AHF) poses a major threat to hospitalized patients for its high mortality rate and serious complications. The aim of this study is to determine whether hypocapnia [defined as the partial pressure of arterial carbon dioxide ...

Frontiers in Physiology, 2020 BackgroundThere is still an urgent clinical need to develop non-invasive diagnostic tests for early ischemic heart disease because, once angina occurs, it is too late. Hypocapnia has long been known to cause coronary artery vasoconstriction.
