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 ...

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).

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

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.

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 ...
