1. A resuscitation management system for a manual resuscitator, the system comprising:
a first accelerometer configured to be mounted on a first side of an outer surface of a resuscitation bag of the manual resuscitator, the first accelerometer configured to measure a first acceleration vector for the first side, the first acceleration vector comprising a first acceleration magnitude as a function of time and a first spatial direction of acceleration;
a second accelerometer configured to be mounted on a second side of the outer surface of the resuscitation bag of the manual resuscitator, the second accelerometer configured to measure a second acceleration vector for the second side, the second acceleration vector comprising a second acceleration magnitude as a function of time and a second spatial direction of acceleration, wherein the second side is opposite the first side along a first axis perpendicular to a longitudinal axis of the resuscitation bag; and
a processing unit coupled to the first accelerometer and the second accelerometer, the processing unit comprising:
at least one processor; and
at least one memory coupled to the at least one processor, the at least one memory storing executable instructions to urge the at least one processor to:
receive the first acceleration vector from the first accelerometer;
receive the second acceleration vector from the second accelerometer;
obtain a resultant acceleration vector by subtracting the second acceleration vector from the first acceleration vector, the resultant acceleration vector comprising an acceleration magnitude as a function of time and a spatial acceleration direction;
calculate a speed of compression/decompression of the resuscitation bag as a function of time for a time interval by integrating the acceleration magnitude as a function of time over the time interval; and
calculate an extent of compression/decompression of the resuscitation bag as a function of time for the time interval by integrating the speed of compression/decompression as a function of time over the time interval.
