The EMST150 is the most clinically validated expiratory muscle trainer and has been proven to be effective in addressing weakened respiratory muscles that in turn cause shortness of breath; medically referred to as Dyspnea.
Dyspnea, or shortness of breath, may be sudden or experienced on a long-term basis and is typically related to a broad range of underlying conditions. It is important to state, if you are experiencing frequent shortness of breath and have not been diagnosed, you should consult a qualified medical professional.
