SUMMARY OF THE INVENTION
An embodiment of the present invention comprises a self-contained breathing apparatus (SCBA) mask that incor- porates a series of physiologic sensors. These physiologic 10
sensors are mounted on the interior of the SCBA mask in
such a way as to contact the facial skin of an inpidual wearing the mask. The physiologic sensors monitor, among other things, heart rate and carbon monoxide and oxygen saturation levels. The SCBA mask also includes a local 15
processor that receives signals from the physiologic sensors
and creates a condition signal indicative of whether a hazard condition exists. The local processor sends the condition signal to a display integrated into the SCBA mask. The display indicates to the inpidual his physiologic status. The 20
display incorporates indicator lights that are integrated into
the mask of the SCBA to indicate, for example, when bottled air must be switched on, to indicate the emergency situation of the wearer and/or to indicate the direction that the wearer
of the SCBA is going. The physiologic sensors are also 25
connected to a transmitting apparatus attached to the SCBA.
The SCBA transmitter sends output data from the physi- ologic sensors to a remote processor. The SCBA transmitter also sends location information of the inpidual wearing the SCBA mask to the remote processor. The remote processor 30
compiles the physiologic and location data for the wearer of
the SCBA and transmits a signal back to the SCBA receiver which, in turn, sends a signal to the display. The remote processor associated with the transmitter also monitors groups of inpiduals wearing the SCBA masks. In this way, 35
the particular status of several inpiduals in the hazardous
environment can be monitored at once and their situation known over a period of time in the hazardous conditions. Specifically, the physiologic condition of the group can be monitored to track the changes in the group condition over 40
the time that the group is exposed to the hazardous envi-
ronment.
