  • Publication number: 20190282772
    Abstract: A positive airway pressure apparatus is disclosed and includes a mask, a micro pump and a processor. The mask is fastened on a user's face and is spatially corresponding to an airway opening of the user, so as to form a closed space. The micro pump is assembled with the cover and is in fluid communication with the exterior of the mask. The processor transmits an actuation control signal to the micro pump so as to actuate the micro pump. Consequently, air is transported into the closed space from the exterior of the mask, and a positive pressure airflow is formed and flows into the airway of the user. A pressure sensor is disposed within the closed space to detect the pressure of the closed space, so that the processor can determine the respiratory state of the user and control the air pressure output of the micro pump correspondingly.

    Abstract: A VOC detecting and warning method is provided. Firstly, an actuating-and-sensing module having a gas transportation actuator and a gas sensor is provided. Then, the gas transportation actuator is enabled to guide a specific amount of gas to the gas sensor in each monitoring time interval, so that each monitored value of a VOC in the specific amount of the gas corresponding to each monitoring time interval is acquired. A plurality of the monitoring time intervals define a time unit. Then, the monitored values during the time unit are added up to obtain a metabolism comparison value. If the metabolism comparison value is larger than a warning threshold value that is defined according to an upper limit of the VOC that a human subject inhales per time unit, the actuating-and-sensing module issues an emergency call, thereby providing a user with a protective measure.
