    Abstract: There is provided a computing device comprising: at least one processor; and a memory comprising instructions that, when executed by the at least one processor, cause the at least one processor to: receive data indicative of a gas characteristic in a sealed space formed by a face of the wearer and a negative pressure reusable respirator; determine performance of a respirator seal check by the wearer; determine that the negative pressure reusable respirator is being worn by a wearer; perform one or more actions in response to determining that the respirator is being worn by the wearer and the wearer has not performed a respirator seal check that satisfies one or more safety rules; and alter the one or more actions in response to determining that the negative pressure reusable respirator is being worn by the wearer and the wearer has performed a respirator seal check that satisfies one or more safety rules. There is also provided a system using such computing device.

    Abstract: A device and a system for monitoring usage of a respirator, and a method of monitoring the respirator are disclosed. The device includes one or more sensors and a computing unit. The one or more sensors generate sensor data during use of the respirator. The sensor data is indicative of one or more parameters associated with the respirator. The computing unit is communicably coupled to the one or more sensors. The computing unit includes a first processor, a first memory communicably coupled to the first processor, and a first communication module communicably coupled to the first processor. The first memory includes at least a first instruction that, when executed by the first processor, causes the first communication module to transmit the sensor data to an external computing device during the use of the respirator.

    IPC: A62B27/00

    Abstract: In some examples, a system includes a respirator; a sensor operatively coupled to the respirator comprising: an electric circuit configured to determine a change in at least one electrical characteristic of a sensing element, wherein the change in the at least one electrical characteristic is based at least in part on detection of a particulate matter; and a computing device configured to: output for display at least one graphical element in a set of graphical elements; in response to receiving the data that is based at least in part on the change in the at least one electrical characteristic of the sensing element, determine, without counting particles of the particulate matter, whether the fit test was satisfied; and in response to the determination whether the fit test was satisfied, perform at least one operation that is based at least in part on the determination whether the fit test was satisfied.
