Abstract:
1. A method for tracking the observance of an oxygen-therapy treatment by measuring the duration of treatment of the patient, wherein the method comprises the steps of: a) providing a device for detecting the observance of an oxygen-therapy treatment with feeding of oxygen to a patient via a cannula delivering oxygen to the airways of the patient, the device allowing the recording of the data of the treatment and the transmission of the data, the device comprising two sensors of absolute pressure, one for measuring the pressure in the cannula, the other for measuring the atmospheric pressure, or a differential pressure sensor; a micro-processor implementing an algorithm capable of transforming the pressure measurements into respiratory frequencies of the patient and of deducing therefrom the duration of the daily oxygen-therapy treatment; a memory chip making it possible to record the data; a radiofrequency antenna making it possible to ensure the wireless transmission of the data; and a battery allowing the system to operate in complete autonomy; b) detecting an oxygen flow rate by measuring a pressure in the cannula supplying the patient's airways with oxygen, c) detecting the patient's respiration by measuring a pressure variation in the cannula, and d) when an oxygen-therapy treatment is detected, transforming the pressure values into respiratory frequency data with the aid of an algorithm and transmitting the respiratory frequency data with the radiofrequency antenna, wherein the method further comprises a step of determining a time period t
