Abstract
An method and system for supplemental gas delivery that enables the identification of a need of therapeutic attention for patient receiving the supplemental gas (20) by detecting an onset of an exacerbation of a medical condition. Such a detection is performed by detecting audible events using a microphone (60) that is in fluid communication with a cannula (28) that is used to communicate the supplemental gas (20) with the airways of the patient (8). The audible event may be, for instance, a cough in the patient. A change in the relative frequency of coughs in the patient may be identified by the routines as being indicative of an onset of an exacerbation.
Claims14
A method of indicating a need of therapeutic attention for a patient receiving a flow of supplemental gas, the method comprising:
- providing a flow of supplemental gas to a patient through a cannula in fluid communication with an airway of the patient;
- detecting within at least a portion of the cannula a plurality of audible events occurring over a period of time that include a current audible event using a microphone operatively coupled to the cannula;
- processing the current audible event to determine from the current audible event whether the frequency over time of such audible events has increased and, if so, making a determination that the patient is experiencing an onset of an exacerbation of a medical condition;
- and
- responsive to the determination, providing to a caregiver or to the patient an output indicative of a need of therapeutic attention for the patient.
7-8. (canceled)
Supplemental gas supply system comprising:
- a processing system comprising a processor and a storage;
- a source of supplemental gas;
- a cannula in fluid communication between the source and an airway of the patient;
- a sensor apparatus operatively coupled to the cannula, the sensor apparatus comprising a pressure sensor, and a microphone both in fluid communication with at least a portion of the cannula, the sensor apparatus being connected with the processor apparatus;
- the processing system further comprising a processor adapted to perform operations comprising:
- detecting a plurality of audible events occurring over a period of time that include a current audible event based on the output of the microphone;
- determining from the current audible event whether the frequency over time of the audible events has increased and, if so, making a determination that the patient is experiencing an onset of an exacerbation of a medical condition based on the current audible event;
- and
- responsive to the determination, providing to a caregiver or to the patient an output indicative of a need of therapeutic attention for the patient.
