Cough Skill Training
During cough skill training, participants will be seated in front of a computer with real-time visualization of their cough waveform. A target line will be provided, and participants will be instructed to perform a single voluntary cough so that their peak flow is within the target's range. Participants will be instructed to continue the cough training regardless of initial accuracy.
