pCO2 values in asphyxiated infants under therapeutic hypothermia after tailored respiratory management: a retrospective cohort study

open access: yesFrontiers in Pediatrics
BackgroundHypoxic-ischemic encephalopathy (HIE) represents one of the major causes of neonatal death and long-term neurological disability. Both hypoxic-ischemic insults and therapeutic hypothermia (TH) can affect respiratory function.

Non-pulsatile blood flow is associated with enhanced cerebrovascular carbon dioxide reactivity and an attenuated relationship between cerebral blood flow and regional brain oxygenation

open access: yesCritical Care, 2019
Background Systemic blood flow in patients on extracorporeal assist devices is frequently not or only minimally pulsatile. Loss of pulsatile brain perfusion, however, has been implicated in neurological complications.

Hyperventilation and seizures in an adolescent female

open access: yesMonaldi Archives for Chest Disease, 2015
A 16 year-old girl was admitted after suffering from recurrent episodes of dyspnea and stridor, cyanosis, loss of contact, stiffening of all four limbs, clenching of the jaw and eye retroversion that lasted for a few seconds to a minute, followed by slow

Knowledge Gaps and Controversies on Cardiopulmonary Exercise Testing in the Assessment of Pulmonary Vascular Disease: An Official Statement of the Pulmonary Vascular Research Institute Exercise and Right Ventricular Function Task Force

open access: yesPulmonary Circulation, Volume 16, Issue 1, January 2026.
ABSTRACT Exercise testing has long been essential for evaluating diagnosis, prognosis, and functional status in pulmonary hypertension (PH). Recent advances have clarified its role in defining reference values and prognostic markers. Nonetheless, substantial knowledge gaps persist regarding the implementation of invasive cardiopulmonary exercise ...

A comparison of dynamic cerebral autoregulation across changes in cerebral blood flow velocity for 200 seconds

open access: yesFrontiers in Physiology, 2014
Objectives: The dynamic interaction between blood pressure (BP) and cerebral blood flow velocity (CBFV) is not fully understood, especially for CBFV changes lasting longer than 50 s.

Human hypoxia models in aerospace medicine: Potential applications for human pharmacological research

open access: yesBritish Journal of Clinical Pharmacology, Volume 92, Issue 1, Page 58-72, January 2026.
Aerospace medicine required controlled terrestrial models to investigate influences of altered atmosphere conditions, such as hypoxia, on human health and performance. These models could potentially be expanded to encompass disease conditions or treatment targets regulated through hypoxia or hypercapnia.

AltitudeOmics: Spontaneous Baroreflex Sensitivity During Acclimatization to 5,260 m: A Comparison of Methods

open access: yesFrontiers in Physiology, 2019
IntroductionBaroreflex sensitivity (BRS) is essential to ensure rapid adjustment to variations in blood pressure (BP). Spontaneous baroreflex function can be assessed using continuous recordings of blood pressure.
