Pregnancy, Sickle Cell Disease and oxygen delivery

TAPS2 feasibility randomised trial. Blood Advances. DOI: 10.1182/bloodadvances.2024012923.

A small feasibility trial examines prophylactic transfusion in pregnancy with Sickle Cell Disease. The study helps separate possible aims of transfusion: reducing HbS, increasing oxygen-carrying capacity and preventing defined maternal or fetal complications.

AABB 2025: RBC transfusion thresholds, clinical context and oxygen delivery

Saifee NH, Andrews J, Berg M, et al. Transfusion. 2026. DOI: 10.1111/trf.70381.

AABB review showing that restrictive versus liberal RBC transfusion effects vary by clinical context, while shelf life, volume and processing constraints can directly limit RBC availability. The analysis connects these findings with the question of oxygen-delivery function.

Prehospital blood transfusion: physiology, oxygen delivery and time

O’Byrne H, Krohmer J, Schaefer R, et al. Trauma Surgery & Acute Care Open. 2026;11(3):e002134.

PHBTC framework showing how prehospital transfusion decisions are driven by hemorrhagic-shock physiology, with restoration of oxygen delivery before critical ischemia as an explicit goal and time-to-treatment linked to outcome.

Severe acute inflammation, microcirculation and tissue oxygenation

Nimmo A, Younsi A. Oxygen. 2026;6(3):22.

Reviews how severe inflammation, endothelial dysfunction, edema and impaired microcirculation can disrupt tissue oxygenation, providing pathophysiological context for Precision Oxygenation Therapeutics and BHOC/HBOC research.

Defining and quantifying oxygen delivery potency of blood products

Rogers SC, Brummet M, Tobin KV, et al. Blood Red Cells & Iron. 2026;2(2):100054.

Introduces the L-TOF framework for comparing oxygen-delivery potency and examines how storage age changes the volume of red-cell products required to match fresh blood.

Nitric oxide scavenging, vasoconstriction and tissue oxygenation

Zhang R, Hess DT, Qian Z, et al. PNAS. 2015;112(20):6425-6430.

Shows why oxygen-carrying capacity alone cannot define effective oxygen delivery: hemoglobin-linked NO bioactivity, hypoxic vasodilation and microcirculatory blood flow are part of the tissue-oxygenation equation.
