Abstract: A self-assessment system for assessing risk for experiencing abnormal airflow during sleep. A preferred embodiment of the system includes a cannula for sampling nasal airflow of a user. A data recording and communication device includes a sensor to receive airflow from the cannula, a converter to convert breathing airflow to an electronic signal, a recorder to record electronic signal data, and a transmitter to wirelessly transmit said electronic signal data. A mobile device includes a receiver to receive said electronic signal data transmitted from the recording and communication device, a database to store the electronic signal data, an interface to obtain questionnaire data from the user, a transmitter to wirelessly transmit the electronic signal and questionnaire data, and a mechanism to store or access instructional video information.
