The Nox T3 Device
The Nox T3 device records signals from five external sensors and three built-in sensors. The external
sensors that can be used with the device are abdominal and thoracic respiratory effort sensors,
oximeter, and two leads of the following: ECG, EMG, EEG or EOG. The built-in sensors include a
pressure transducer allowing either recording of nasal pressure or mask pressure, a three dimensional
acceleration sensor for measure of patient’s position and activity, and a microphone for measuring of
snoring and true audio recording capabilities. The arrangement of sensors will be determined by the
type of study being performed. The device is worn on the patient’s chest by snapping it to the thoracic
respiratory sensor and securing its position with the clip straps. The device is powered with one AA
battery. The device has a display for status indication, signal integrity and preliminary results, and
buttons for control and event marking.
Interfaces
The Nox T3 device interface consists of a display, buttons, sensor inputs/connections and a USB
connector. The USB connector is placed under the locked battery lid making it inaccessible and tamper
prove for children, and connects to the USB cable for device configuration and data download. See the
figures and tables below for detailed description.
