Artificial Intelligence in Neonatal Care: The Breadth of Promise, the Depth of Challenge—An Overview

Journal of Paediatrics and Child Health, EarlyView.
ABSTRACT Artificial intelligence (AI) is becoming an integral tool in clinical care. The recent position statement by the Royal Australasian College of Physicians (RACP) provides a timely practical blueprint on implementing and monitoring the use of AI in clinical practice.

Impact of Hypoxemia Severity on Cardiac Autonomic Regulation in Children With Sleep‐Disordered Breathing: A McGill Oximetry‐Based Analysis

Journal of Sleep Research, EarlyView.
ABSTRACT Sleep‐related breathing disorders (SRBD) represent a significant paediatric health concern. Traditional polysomnographic indices, such as the apnoea–hypopnoea index, may not fully capture the physiological burden of paediatric SRBD, highlighting the need to better characterise the impact of nocturnal hypoxemia on cardiac autonomic regulation ...

Cerebral oxygen extraction across different exercise intensities: Role of arterial PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_2}}}$

Experimental Physiology, EarlyView.
Abstract Stability in cerebral oxygen extraction fraction (OEF) is typically determined by alterations in cerebral blood flow (CBF). At rest, arterial partial pressure of carbon dioxide (PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_2}}}$) and OEF exhibit a strong inverse relationship owing to the powerful influence of PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_2}}}$

The Various Oximetric Techniques Used for the Evaluation of Blood Oxygenation

Sensors, 2020
Adequate oxygen delivery to a tissue depends on sufficient oxygen content in arterial blood and blood flow to the tissue. Oximetry is a technique for the assessment of blood oxygenation by measurements of light transmission through the blood, which is ...

Carotid artery dissection linked to intermittent apnoeic swimming: A case–control study

Experimental Physiology, EarlyView.
Abstract Internal carotid artery (ICA) dissection is a rare and potentially devastating cause of cerebral ischaemia, initiated by an intimal tear or rupture of the vasa vasorum, that can lead to an intraluminal thrombus, vascular stenosis, occlusion, or dissecting aneurysm formation.

The effects of anaesthesia induction with propofol or ketofol on cerebral oxygenation in patients above 60 years of age

Medicine Science, 2020
Side effects such as hypotension and cerebral perfusion disorder may be encountered after anaesthesia induction, especially in elderly patients. Some studies have attempted to determine whether hypotension during induction and associated organ perfusion ...

A comparison of normobaric and hypobaric hypoxia effects on cerebrovascular response pre and post maximal exercise

Experimental Physiology, EarlyView.
Abstract A lack of consensus remains on whether normobaric hypoxia (NH) and hypobaric hypoxia (HH) may differentially impact physiological factors affecting cerebrovascular regulation, particularly with an additional strenuous exercise component. We sought to compare the acute effects of NH and HH on global cerebral blood flow (gCBF) at an altitude ...

Prediction of acute mountain sickness occurring at 4554 m using overnight pulse oximetry from lower altitude: A pilot study

Experimental Physiology, EarlyView.
Abstract Acute mountain sickness (AMS) affects many individuals ascending to high altitude annually, carrying potential morbidity and mortality risks (e.g., high‐altitude cerebral oedema). The objective of this pilot study was to record overnight pulse oximetry during ascent to 4554 m and determine whether: (1) extracted overnight biomarkers had any ...

The contributions of nocturnal hypoxaemia and sleep disturbances to acute mountain sickness

Experimental Physiology, EarlyView.
Abstract Acute mountain sickness (AMS) is common after ascent to altitude, yet individual susceptibility remains difficult to predict and diagnosis relies on subjective report. Sleep disturbances and nocturnal hypoxaemia at altitude may provide insight, but their relationship to AMS is incompletely understood.
