Breathing With a Facemask Exercise Performance

Correlation between dyspnea as measured by the device and reported dyspnea by subjects

This study will determine the dyspnea response in chronic lung disease volunteers during
 treadmill walking with and without added inspiratory resistance. This study will also
 determine the level of dyspnea and exercise sense of effort in individuals walking on a
 treadmill when elevations occur. Comparisons will be made of a participant's exercise
 response with and without increased inspiratory resistance. In this study, exercise
 performance will be analyzed based on physiological and perceptual measures. The participant
 will undergo two sessions: one session will be a standard exercise walking test without an
 inspiratory resistance; the other session will be the same standard exercise walking test
 while breathing with an inspiratory resistance equal to a N95 facemask (R=10-15 cmH2O/L/sec).
 Performance will be determined by physiological measures. Perception will be determined by
 scores based on numerical scales and automatically with the forehead Vitality remote
 monitoring sensor.
