Your understanding about eflow rapid snd Pulmozyme is not correct. FDA approwed eflow for use with P. You should check what kind of informations you are sharing.In the past when traveling I've used a Pari Trek S for both Hypersal and Pulmozyme. The battery was good for up to five treatments, depending on the treatment time.
I've also used a Pari eFlow for Hypersal, keeping separate Altrea handsets just for that purpose. My understanding is the eFlow should not be used for Pulmozyme because it can damage the Pulmozyme molecules.
