Abstract: Systems and methods for breathing training and methods to monitor their use are disclosed. According to an aspect, a breathing training monitoring system may include a gas passageway that is occluded or connected to a RMT device for receipt of input from a patient. Further, the system may include a gas pressure transducer configured to measure gas pressure within the gas passageway. The system may include a breathing activity monitor configured to determine whether a breathing activity has been accomplished based on the measure of gas pressure. The breathing activity monitor may also present an indication that the breathing activity has been accomplished in response to determining that the breathing activity has been accomplished.

Abstract: Breathing training device adapters and associated methods are disclosed herein. According to an aspect, a breathing training device adapter includes a housing comprising a first end and a second end that each define an opening. The housing defines an interior space that extends between the first end and the second end to enable gas flow between the opening of the first end and the opening of the second end. The adapter may include a first connector configured to operatively connect the opening of the first end to a breathing training mouthpiece as well as a gas valve operatively connected to the housing to provide controlled gas flow between the interior space of the housing and outside the housing. Further, the adapter may include a second connector configured to operating connect the opening of the second end to a breathing training device.
