US 2024/0390622 A1 · SENSOR-BASED SYSTEM FOR RESPIRATORY MONITORING AND AUTOMATED ADJUSTMENT OF OXYGEN DELIVERY

Abstract

A sensor-based system for monitoring a person's breathing automatedly detects respiratory distress, and automatedly adjusts oxygen delivery to mitigate the distress. The system preferably uses non-invasive touchless sensors, such as a camera/imagine device or microphone, or low-touch sensors, such as a wearable pulse oximeter, heart rate sensor or respiration rate sensor configured with low-tack adhesive or straps. The wearable sensors may transmit data wirelessly without associated cables that could damage the person's skin. A non-invasive oxygen delivery system includes a control module operable to control a flow of oxygen from an oxygen source via the oxygen delivery appliance (wearable nasal cannula/mask) as a function of data gathered by the sensors, e.g., to increase a concentration, flow rate or pressure of oxygen delivered to the person when the person is determined to be in respiratory distress, until the distress abates, at which time oxygen delivery may be further adjusted.

Dependent claims

A sensor-based system for monitoring a person's breathing to automatedly detect a respiratory distress state, and for automatedly adjusting oxygen delivery to the person to mitigate the respiratory distress state, the system comprising:

a monitoring system comprising:
at least one non-invasive sensor configured to gather data associated with at least one aspect of a person that is indicative of the respiratory distress state;
and
a respiratory assessment module operable to process data gathered by said at least one non-invasive sensor to determine whether the person is in the respiratory distress state;
and
an oxygen delivery control module operable to transmit a control signal configured to control a flow of oxygen from an oxygen source as a function of data gathered by said at least one sensor of said monitoring system.

3 more elements

A method for monitoring a person's breathing to automatedly detect a state of respiratory distress, and for automatedly adjusting oxygen delivery to the person to mitigate the respiratory distress state, the method comprising:

monitoring a person for a state of respiratory distress with a non-invasive sensor configured to capture sensor data associated with the person;
processing the sensor data to determine whether the person is currently in the respiratory distress state;
and
if the person is currently in the state of respiratory distress, then:
transmitting a first control signal to an oxygen flow control module to control a flow of oxygen from an oxygen source to the person by increasing at least one of an oxygen concentration in a gas flow, a gas flow rate, and a gas flow pressure of the gas flow.
