CoughAssist by Phillips Respironics Inc. is a noninvasive therapy that safely and consistently removes secretions in patients with an ineffective ability to cough (peak cough flow <270 l/m).

The Frequencer^TM V2X designed for hospital use is a digitally controlled airway clearance device that utilizes acoustic waves to promote bronchial drainage by inducing vibrations (via acoustic waves) in the chest wall of a patient. The device provides a gentler, less painful form of therapy for patients than the traditional “clapping” method of postural drainage therapy and is less demanding for physiotherapists responsible for providing this therapy.
