Oxygen mask respirometer
Devices, systems, and methods for monitoring respiration using surface temperature, humidity, air pressure, carbon dioxide gas sensors, pulse oximetry sensors and electromyography sensors, and/or acceleration sensors to obtain information related to respiration rate (RR), exhalation/inhalation strength, exhalation/inhalation volume, exhalation/inhalation acceleration, and/or exhalation/inhalation regularity.
1 . A device for monitoring one or more respiratory attributes of a user, comprising:
a housing;
a fastener on an outer surface of the housing, wherein the fastener is capable of attaching the housing to an oxygen mask;
two or more sensors located within the housing,
wherein the two or more sensors comprise a temperature sensor configured to detect a surface temperature of the user's skin covered by the oxygen mask when the oxygen mask is placed over the mouth of the user;
one or more processors located within the housing, said one or more processors configured to execute machine executable code causing the one or more processors to:
receive a set of data comprising two or more datasets output from the two or more sensors;
perform an autocorrelation on each of the two or more datasets to determine autocorrelation results;
compare the autocorrelation results with a potential respiratory attribute pattern to determine an average peak correlation for each dataset;
select the dataset with the highest average peak correlation for further analysis;
analyze the selected dataset to determine one or more respiratory attributes;
detect one or more respiratory events based on the determined one or more respiratory attributes;
and
generate an output identifying the detected one or more respiratory events; and
a digital display located within the housing, wherein the machine executable code further causes the one or more processors to display the output on the digital display.
