Abstract

We have developed different portable tools based on phosphorescence lifetime and intensity measurements to be used together with syringes, needles, and catheters to measure oxygen partial pressure deep inside tissue with the aim to improve the assessment of acute compartment syndrome (ACS). Due to their portability and universality, the tools will also be useful in other hypoxia-related conditions such as vascular diseases, diabetic wounds, cancer, and traumatic injuries. We will present designs as well as results from in vivo porcine model studies.
