Claim of US Patent No. 9,439,577

1. A non-invasive method for measuring cardiac output, comprising
administering to a subject a hyperbaric or hypobaric gas and measuring changes in central or peripheral oxygen saturation
with time using pulse oximetry at a peripheral body site representative of central circulation times, wherein time is measured
from the time of administration of the hyperbaric or hypobaric gas to the measurement taken at the peripheral body site.
