Advocacy Voices
& Field Notes

We listen to the people this work is for, share their questions and answer them openly.

People waiting for a transplant. People living with one. Families and care partners who stay beside them. Their experience belongs in the conversation about oxygen delivery and organ sustainability.

Jeff Parke

Founder and Executive Director
Cold Ischemia Foundation

Jeff brings personal experience of kidney transplantation and a background in clinical research. He asks what patients and care partners need to understand about the technologies being developed for them.

His Foundation has published an introduction to BHOC and a series of Field Notes. We link to his original pages so readers can hear his perspective directly.

Field Notes

Two places to begin.

Independent essays that open useful questions about oxygen delivery and how outcomes are measured.

01 / Temperature

Cold Oxygen

Jeff explores how cooling changes the conditions for oxygen delivery to an organ, and what that means for oxygen-carrier research.

02 / Measurement

How Do You Know It Worked?

An essay on measurement, surrogate endpoints and the questions behind a claim of improved oxygen delivery.

These are independent external essays, presented as perspectives for discussion. They do not establish BHOC-specific clinical outcomes. Scientific findings are reviewed separately in our Evidence section.
