  • Non-invasive estimation of arterial blood gases
    Patent number: 6251082
    Abstract: A non-invasive system and procedure for deriving the blood gas content for a patient. The system measures the carbon dioxide concentration of the expiratory breath relative to volume. This data is then processed to derive arterial blood gas levels of carbon dioxide. If data sampling is in the time domain, the processing shifts the data from the time domain to the volume domain. The processing also iteratively assesses the significance of numerous variables. The resulting relationship provides a fast and accurate measure of blood gas content for both healthy and diseased lung patients.
    Type: Grant
    Filed: August 27, 1998
    Date of Patent: June 26, 2001
    Assignee: NTC Technology, Inc.

  • Non-invasive estimation of arterial blood gases
    Patent number: 5632281
    Abstract: A non-invasive system and procedure for deriving the blood gas content for a patient. The system measures the volume and carbon dioxide concentration of the expiratory breath and discerns breath volumetric rate and gas content. This data is then processed to derive arterial blood gas levels of carbon dioxide. The processing shifts from the time to the volume domain and iteratively assesses the significance of numerous variables. The resulting relationship provides a fast and accurate measure of blood gas content for both healthy and diseased lung patients.
