  • SYSTEM AND METHOD FOR MONITORING A BLOOD FLOW THAT DOES NOT INTERACT WITH VENTILATED LUNGS OF A PATIENT
    Publication number: 20210315469
    Abstract: A method and a system to monitor the progression of a pulmonary ailment in patients who are mechanically ventilated or spontaneously breathing. By delivering specific gases to the patient and monitoring the release of those gases over various timescales, the system monitors the progression of pulmonary shunt. No invasive procedures are required, and the system is able to operate through the sole delivery and monitoring of respiratory gases.

  • Method and system for estimating the efficiency of the lungs of a patient
    Patent number: 11000209
    Abstract: The present disclosure relates to methods and systems for estimating an efficiency of lungs of a patient receiving respiratory care. A blender has a primary input port for receiving a first gas to be delivered to the patient and one or more secondary input ports for receiving a second gas to be delivered to the patient from one or more gas sources. A patient-side port of the blender delivers the first and second gases to the patient. A gas composition sensor measures a fraction of the first gas and a gas flow sensor measures a flow of the first gas. A controller causes a sequential delivery of the first and second gases to the patient and estimates a functional residual capacity of the patient based on measurements from the gas composition sensor and from the gas flow sensor. The controller may also estimate a cardiac output of the patient.
