Regional oxygen uptake/perfusion measuring device and method

摘要

To assess regional oxygen uptake and/or perfusion in a patient, a volume of air inhaled by the patient is determined and, according to a method of electrical impedance tomography, a first regional lung volume is measured at a first time point of a breathold procedure. The first regional lung volume is compared to a second regional lung volume at a second time point of the breathold procedure.

主权项

1. A device comprising:
an electrical impedance tomography (EIT) device configured to measure a regional lung volume without use of a contrast marker, wherein the device is configured to:
measure with the EIT a first regional lung volume at a first time point of a breathold procedure and at a second time point of the breathold procedure;determine a change in the first regional lung volume; anddetermine a first regional oxygen uptake based at least in part on the change in the first regional lung volume.
