Hypoxic Burden in Children With Sleep‐Disordered Breathing: Determinants and Correlates

open access: yesJournal of Sleep Research, Volume 35, Issue 2, April 2026.
ABSTRACT Hypoxic burden (HB) is an emerging metric for quantifying intermittent hypoxia associated with sleep apnea, offering potential advantages over traditional measures such as the apnea‐hypopnea index (AHI). This study evaluated the distribution and clinical significance of non‐respiratory event‐specific HB in children and adolescents with ...

α‐Adrenergic blockade impairs ductus venosus shunting during an acute period of fetal hypoxaemia without further deficits to cerebral oxygen delivery

open access: yesExperimental Physiology, Volume 111, Issue 4, Page 1796-1807, 1 April 2026.
Abstract The fetal circulation has unique shunts, including the ductus venosus (DV), the tone of which dictates how much substrate‐rich blood returning from the placenta is streamed preferentially away from the liver and instead towards the heart. Herein, we aimed to use clinically relevant MRI techniques in sheep to measure indirectly induced changes ...

Interpreting peripheral oxygen saturation variability in critical illness: A directional framework adjusted for hypoxia severity

open access: yesExperimental Physiology, Volume 111, Issue 4, Page 2334-2347, 1 April 2026.
Abstract Peripheral oxygen saturation (SpO2${S_{{\mathrm{p}}{{\mathrm{O}}_2}}}$) exhibits a complex pattern of fluctuations during hypoxia, which can be quantified using entropy measures. SpO2${S_{{\mathrm{p}}{{\mathrm{O}}_2}}}$ entropy analysis provides insights into dynamic physiological regulation by non‐invasively reflecting the body's capacity to ...

Cardiovascular, respiratory and splenic responses to rebreathing and apnoea during exercise

open access: yesExperimental Physiology, Volume 111, Issue 4, Page 1971-1987, 1 April 2026.
Abstract We investigated integrative physiological responses to eupnoeic exercise (EX), rebreathing exercise (RB), dynamic apnoea (DA) and dynamic apnoea with cold‐water face immersion (DAFI) in 20 healthy participants. Trials involved non‐steady‐state cycle exercise at 60 W for an average duration of 66 s.

Oxygen and glucose supplementation increases rates of linear growth and cell proliferation in growth‐restricted fetal sheep

open access: yesThe Journal of Physiology, Volume 604, Issue 7, Page 2778-2795, 1 April 2026.
Abstract figure legend Effects of sustained oxygen and glucose supplementation on growth and cellular proliferation in growth‐restricted fetuses. This study evaluated whether supplemental oxygen and glucose could improve growth rates in sheep fetuses with established fetal growth restriction (FGR). Following the induction of placental insufficiency and
