📖 About BHOC
BHOC (Biological Hemoglobin Oxygen Carrier) is a hemoglobin-based oxygen carrier platform focused on supporting oxygen delivery beyond the conventional red blood cell transfusion model.
The central concept is Precision Oxygen Therapeutics: focusing on oxygen delivery at the tissue level rather than on blood hemoglobin concentration alone.
BHOC is intended as a complementary approach to the oxygen-delivery function of blood, while recognizing that blood performs many other essential physiological functions.
🎯 Precision Oxygen Therapeutics
Precision Oxygen Therapeutics focuses on four fundamental questions:
- 📍 WHERE — Where is oxygen needed?
- ⏰ WHEN — When is additional oxygen delivery required?
- 📊 HOW MUCH — How much oxygen is required to support tissue demand?
- 🎮 CONTROL — How can oxygen delivery be supported in a controlled and continuous manner?
The objective is to move the focus from simply increasing circulating hemoglobin toward understanding and supporting oxygen availability at the tissue level.
🫁 Tissue-Level Oxygen Delivery
Systemic measurements such as hemoglobin concentration and arterial oxygen saturation are important indicators of oxygen transport.
However, tissue oxygenation is influenced by multiple physiological processes, including:
- Oxygen content
- Cardiac output
- Microcirculation
- Oxygen extraction
- Diffusion
- Tissue oxygen demand
- Cellular oxygen utilization
BHOC research and development is centered on the broader question of how hemoglobin-based oxygen transport can contribute to oxygen availability at the tissue level.
🔄 How Oxygen Delivery Works
A simplified oxygen-delivery pathway can be represented as:
Oxygen Loading → Transport → Distribution → Oxygen Unloading → Tissue Availability → Cellular Utilization

🩸 BHOC and Blood
Blood performs many essential physiological functions, including:
- Oxygen carrier transport and distribution
- Cellular and protein components that are critical to osmotic pressure fluid balance
- Carbon dioxide transport
- Coagulation
- Immune system management functions
- Acid-base regulation as well as ionic balance
- Signaling and other biological functions
BHOC focuses specifically on the cooperative oxygen-delivery and distribution function.
Therefore, BHOCs have been developed and evaluated as an immediate and complementary oxygenation support, rather than as a substitute for all functions of blood.
🔬 Research Areas
BHOC is relevant to cellular regeneration research across many areas of life function support and "oxygen therapeutics" where transfusion and perfusion sciences are critical:
- Hemoglobin-Based Oxygen Carriers (HBOCs)
- Oxygen Therapeutics
- Precision Oxygenation
- Tissue Oxygenation

🏥 Potential Applications
Research (applied) and development may explore applications where oxygen delivery is compromised, delayed, limited, and/or pressure limited and requires additional support.
Potential areas include:
- Trauma and acute blood loss
- Prehospital and emergency medicine
- Surgery
- Organ preservation and transplantation
- Machine perfusion
- Ischemia and reperfusion
- Veterinary medicine and all animal health regardless of species
- Blood-supply constrained environments
- Resource-limited healthcare settings
Applications must be evaluated according to the available scientific and clinical evidence. Animal health models and experience can prescreen logistics and value of immediate intervention.

🧬 Scientific Principles — Oxygen Pathway
The development of Precision Oxygen Therapeutics requires understanding the relationship between:
Oxygen Supply (lung and membrane oxygenation and anti-oxidation control)
↓
Oxygen Transport (rheology and diffusion support, ECMO)
↓
Microvascular Distribution (perfusion and concentration)
↓
Tissue Oxygen Availability (extraction and control)
↓
Cellular Oxygen Utilization
The ultimate biological objective of oxygen delivery is not simply the presence of oxygen in the circulation, but its exchange with tissues and cells.
🌟 BHOC Vision
The long-term objective is to advance a scientific framework in which systemic and organ and tissue oxygen delivery can be regenerative as a therapeutic function:
- 📍 Where oxygen is needed
- ⏰ When oxygen is needed
- 📊 In the amount oxygen is needed
- 🎯 Continuously and controllably at the cell and mitochondrial level
