It has been hypothesised that a higher peak expiratory flow rate, tidal volume and airway pressure would be more efficient in secretion removal and reversing atelectasis in an intubated patient (Kim et al 1986, King et al 1992, Maxwell and Ellis 1998).

In the recent collaboration with the Koto Hospital in Tokyo, the company has confirmed that a long-time ingestion (at least 6 months) of tomato juice helps alleviate the subjective symptoms of BA while improving the peak expiratory flow rate, an index of BA.
