Schematic flow curve of mechanical insufflation-exsufflation: with bulbar dysfunction the flow flattens early during insufflation and collapses after the peak during exsufflation, compared with the dashed normal course.

Bulbar Dysfunction in ALS: When Mechanical Insufflation-Exsufflation Reaches Its Limits

Mechanical insufflation-exsufflation (MI-E) is an established technique for cough augmentation in neuromuscular disease. In bulbar dysfunction, however, the upper airway can become the limiting factor. Why more pressure does not always mean more effect.

Schematic pressure curve of a BiWaze Cough cycle: pause with positive pressure maintained, insufflation with positive pressure, immediate switch to negative pressure during exsufflation, then another pause above zero.

PAP on Pause: Why the BiWaze Cough doesn't simply drop to zero between cough cycles

Between two cough cycles, the BiWaze Cough maintains a positive airway pressure during the pause phase. What this function is based on, how it fits into the therapy cycle and what the technical data actually show.

BiWaze Cough vs. BiWaze Clear: Two Different Jobs in Secretion Management

Both devices are used with patients who have secretion problems, but they do fundamentally different things: one supports a missing cough, the other loosens and mobilises secretions. Mixing them up means picking the wrong device at the bedside.

Dual Lumen Breathing Circuit: now CE-marked in Europe

One circuit, two paths: the Dual Lumen Breathing Circuit for BiWaze Cough & BiWaze Clear separates inhaled and exhaled air within a single set. This article explains what that means for everyday use at the device.

BiWaze Clear now available: what the device does

BiWaze Clear carries CE marking and is now available in Europe. It combines lung expansion, secretion mobilisation and aerosol delivery in one closed circuit. A short overview of how it works.

Therapy cycle with CoughCue: inspiratory flow rises in an S-curve and levels off into a plateau. At the end of the plateau, CoughCue detects the end of inspiration and switches over. The curve drops steeply through the zero line into a deep, narrow peak – a higher peak cough flow – and then slowly returns to zero.

CoughCue: synchronising exsufflation with the patient’s own breathing

CoughCue detects the moment the lungs are full on the BiWaze Cough and starts exsufflation exactly then. How the two trigger types work, what the inspiratory hold time does, and how CoughCue differs from the inspiratory trigger.
