When can oxygen support create time?
Define the window in which immediate oxygen-carrying support may bridge to hemorrhage control, surgery, disease-specific therapy, compatible blood or endogenous erythropoiesis.

Regulatory and publication evidence
BHOC-platform Veterinary Regulatory & Science
Return to the Veterinary section for Oxyglobin regulatory records, FDA and EMA sources, and the indexed veterinary publication archive.
FDA primary evidence · Canine field trial
95% treatment success vs 32% control
Efficacy population: Oxyglobin 20/21 vs control 9/28; p≤0.001. Intent-to-treat: 73% (22/30) vs 29% (10/34).
FDA endpoint: no additional oxygen-carrying support required for 24 hours. This is a treatment-success endpoint, not survival.
Historical canine archive · Interpretation layer
From 885 reports to three research questions.
Oxyglobin Solution - Case Listing Book II is a manufacturer-collected descriptive archive, not a controlled efficacy trial. It contains 885 veterinary reports from 1998-1999 and 146 selected printed canine vignettes. Its recurring clinical pattern is oxygen-carrying support used as a bridge while definitive treatment addressed the cause.

Which endpoints capture function?
PCV measures red-cell volume, not plasma hemoglobin. Total hemoglobin, circulation, unloading, tissue demand and clinical physiology must be considered together.
What can translate beyond dogs?
Canine history can define research questions. It cannot establish formulation, dose, rate, safety, efficacy or approval in another species.
Evidence boundary: descriptive, product-specific and selection-prone. The archive is separate from the controlled FDA field trial and is not evidence of BHOC efficacy. The full scan is not republished while redistribution rights remain unconfirmed.
Evidence portal taxonomy
One entry point. Clear evidence boundaries.
Oxyglobin regulatory evidence
Dog indication, FDA endpoint, product history and primary regulatory sources. Approval must not be transferred to other species or BHOC.
Feline evidence
Cat donor-blood constraints, case literature and clearly labelled off-label or translational oxygen-carrier evidence.
Equine medicine
Equine surgery, hemorrhage, transfusion logistics, oxygen physiology and species-specific safety questions.
Camelids
Camel and camelid oxygen biology, distinctive erythrocyte physiology and evidence gaps relevant to development.
Avian, raptor & parrot
Avian respiratory physiology and evidence requirements for birds, falcons, raptors and parrots.
Wildlife & conservation
Zoo, wildlife, marine and endangered-species care with independent biodiversity sources and no endorsement claims.
Publications & safety
Publication taxonomy for efficacy, dosing, NO scavenging, vasoconstriction, methemoglobin, renal and immunologic safety.
Veterinary blood systems
Animal blood banks, donor availability, crossmatching, storage, wastage and the multifunctional role of donor blood.
Oxyglobin & HBOC studies
Six directly relevant historical publications with original sources. The complete bibliography remains in the central BHOC catalogue.
BHOC development
BHOC means Biological Hemoglobin Oxygen Carrier. It is a developing product category with an emerging evidence base, not a transferred approval claim.
Concepts & Questions
Developing veterinary questions, hypotheses and pre-publication analysis kept separate from established evidence. First concept: donor welfare, feline blood donation and an additional oxygen-delivery layer.
Hemoglobin & other oxygen-carrying pigments
Nature uses more than one hemoglobin strategy.
Hemoglobin
Iron-containing heme protein and the central oxygen carrier across almost all vertebrate life.
Hemocyanin
Copper-based oxygen carrier found in many molluscs and arthropods.
Hemerythrin
Non-heme iron oxygen-binding protein found in several marine invertebrate groups.
Chlorocruorin
Greenish extracellular respiratory pigment found in certain marine polychaete worms.
Erythrocruorin
Large extracellular hemoglobin complex found in annelids and some other invertebrates.
Antarctic icefish
A notable vertebrate exception: adult crocodile icefish lack functional hemoglobin and rely on specialized cold-water physiology.
Nature Is a Great EngineerHeme and chlorophyll are built on closely related tetrapyrrole chemistry. Their molecular architecture follows the same fundamental biological design, but with a remarkable change at the center: Different metals. Related molecular architecture. Different functions.
The same extraordinary engineering logic of nature.
