Measuring how well blood delivers oxygen.

Blood banks track how old each unit of blood is. OxyHeme is building a rapid test that shows how well it can still release oxygen.

Oxygen dissociation curve Hemoglobin saturation rises steeply as oxygen pressure increases, then levels off near full saturation. P50 marks the oxygen pressure at which hemoglobin is half saturated.
The oxygen dissociation curve. P50 is the oxygen pressure at which hemoglobin is half saturated.

About

Blood’s most important job is to deliver oxygen. Today, no routine test checks how well a unit of blood can do it.

Donated blood is screened for safety, matched to the patient and used before its expiration date. None of those steps measures how readily the blood will release oxygen, and that ability can vary, even among units that are safe and within date.

OxyHeme is developing a fast, scalable test that measures oxygen release directly, so blood can be judged by how well it works as well as how long it has been stored.

Founded by researchers at Case Western Reserve University. Based in Cleveland, Ohio.
