Respirogen micron-scale Oxygen Microbubble (OMB) technology will provide improved compositions and methods for blood oxygenation as well as improved methods for producing and delivering these oxygen delivery compositions to patients and explanted cells, tissues, or organs. Every cell in the body requires oxygen to maintain correct homeostasis, and hypoxic conditions can quickly lead to irreversible organ damage or death. OMB technology has demonstrated the ability to deliver oxygen to the blood stream independent of the lungs.
Tight control of the size and composition allows for microbubbles to carry oxygen, other gases, or therapeutic agents to targeted physiology: well characterized; easy to transport; stable; inexpensive to produce.
Targeted delivery will increase delivery effectiveness while reducing side effects compared to systemic infusions: oxygen can be retained within the microbubble until it encounters a hypoxic environment, facilitating targeted oxygen delivery to ischemic tissue and organs; lipid retention after delivery shows positive oncotic properties, increasing the blood volume and offering reduced morbidity in events of hemorrhage.
Delivery of oxygen by defined protocols: ability to deliver a quantified oxygen concentration over a defined time period to a specified anatomical region of interest; potential for a portable oxygen delivery therapy kit in first response or remote situations.
Peritoneal oxygenation - oxygen uptake without the lungs - has been validated in vivo in a small animal model
