  When the inhalation gas supply system 10B determines that the user's breathing has stopped, the management server 20 provides the doctor terminal 30, the nurse terminal 40, and the family terminal 50 as breathing state determination information. By transmitting the respiratory stop state data, the doctor, nurse, and family are informed that “the user's breathing has stopped”.

According to this embodiment, there are the following effects.
That is, the management server 20 transmits the breathing state determination information from the inhalation gas supply system 10B to a predetermined one of the doctor terminal 30, the nurse terminal 40, and the family terminal 50 according to the breathing state of the user. did. For this reason, a user's respiratory state can be alert | reported to an appropriate thing among a doctor, a nurse, and a family.

<Modification>
It should be noted that the present invention is not limited to the above-described embodiment, and modifications, improvements, etc. within a scope that can achieve the object of the present invention are included in the present invention.
For example, the sensor unit 114 is configured by the carbon dioxide partial pressure sensor 114A, the internal pressure sensor 114B, and the flow rate sensor 114C, but is not limited thereto, and may further include a temperature sensor. According to this, by measuring the temperature data related to the temperature of the exhaust gas discharged by the user with the temperature sensor and using it when estimating the user's breathing state, the user's breathing state can be estimated more accurately. .
Further, the tube portion 115 is provided such that one end is connected to the tube insertion device 13 and the other end is inserted through the inside of the inhalation gas supply conduit 119 and the mask portion 111 so as to be inserted from the user's nasal cavity to the trachea. However, the other end may be provided so as to be inserted from the user's larynx to the trachea through the inside of the inhalation gas supply conduit 119 and the mask portion 111.
