Systems and methods for automated respirator

A computer-implemented method for operating a negative pressure reusable respirator configured to cover at least a mouth and a nose of a wearer to form a sealed space, the method comprising:

• receiving, from a first sensor, first sensor data indicative of a gas characteristic in the sealed space;
• receiving, from a second sensor, second sensor data indicative of a state of at least one valve of the respirator;
• determining comparative data by comparing the first sensor data and the second sensor data;
• based at least in part on the comparative data, determining at least one of:
• usage information related to the respirator or a physical state of the respirator;
• and
• performing at least one operation in response to the determining, the at least one operation comprising at least one of:
• generating an output perceptible by the wearer;
• and
• sending a message to another computing device.

An accessory apparatus configured to be removably attached to a negative pressure reusable respirator that, when worn by a wearer, forms a sealed space with a face of the wearer, the apparatus comprising:

• a housing;
• a communication unit configured to receive identification information from a contaminant capture device coupled to the respirator;
• a first sensor configured to generate first sensor data indicative of a gas characteristic within the sealed space;
• a second sensor configured to generate second sensor data indicative of a state of at least one valve of the respirator;
• an output interface configured to generate an audible, visual, or haptic output perceptible by the wearer;
• and
• a computing device comprising at least one processor and a memory storing instructions that, when executed, cause the processor to:
• determine, based at least in part on the identification information, whether the contaminant capture device is present, authentic, and appropriate for a work environment;
• determine, based at least in part on the first sensor data and the second sensor data, usage information comprising at least donning of the respirator, respiration through the at least one valve, and an occurrence and performance characteristic of a wearer seal check;
• and
• perform at least one operation selected from:
• generating an output at the output interface and sending a notification to another computing device.
