  • Face mask for gas monitoring during supplemental oxygen delivery
    Patent number: 7004168
    Abstract: A face mask including a gas monitoring capability for improved patient management in combination with improved efficiency of supplemental oxygen delivery to the patient is provided. The face mask of the present invention is configured to direct substantially all of the inspiratory and expiratory gas streams to and from the patient through a gas measuring device and to efficiently deliver supplemental oxygen. As such, the face mask permits measurement of both oral and nasal gas exchange.
    Type: Grant
    Filed: August 29, 2002
    Date of Patent: February 28, 2006
    Assignee: Respironics, Inc.
    Inventors: Leslie E Mace, David R Rich, Randall J Terry, John A Triunfo, Jr., Anthony T Pierry, Michael J. R. Polson

  • Method of measuring the oxygen saturation in pulsating blood flow
    Patent number: 5448991
    Abstract: An improved pulse oximeter for the measurement of oxygen saturation in the blood, which is faster and more accurate than conventional pulse oximeter. Improved speed and accuracy is attached by elimination of normalization and feedback circuitry and the use of analog to digital converting devices having a wide dynamic range along with a sophisticated computer analysis. The instant invention eliminates inaccuracies resulting from channel matching errors, and detects and eliminates aberrant input data.
