Mary Kiige: Biological Hemoglobin Oxygen Carrier as a Lifesaving Oxygen Bridge

Mary Kiige, Founder of Kikwetu Digital Solutions and Digital Innovation Strategist, has shared a post on LinkedIn:

“Can BHOC – Biological Hemoglobin Oxygen Carrier Replace Blood?
The short answer: No!

But here’s why that matters, and why it’s still revolutionary.
What BHOC cannot do:
It doesn’t replace platelets or plasma proteins.
It can’t provide clotting factors or immune cells.
It’s not a complete substitute for blood transfusion.

What BHOC can do:
Deliver oxygen instantly to tissues when red cells can’t.
Work for all blood types (no cross-matching needed).
Stay shelf-stable for 3+ years at room temperature.
Serve as a bridge therapy, buying time until blood or definitive treatment is available.

Real-world use:
Approved in South Africa since 2001.
Used under FDA Expanded Access in the U.S. for patients when blood was not an option.
Applied successfully in trauma, surgery, transplantation, and rare antibody cases.

The takeaway:
BHOC isn’t a blood replacement, it’s a lifesaving oxygen bridge.
When blood is scarce or unavailable, it creates the one thing medicine needs most: TIME!”
