IPV - adjuvant therapy in COPD exacerbations ?

A study of 33 patients, published from france last year on acute exacerbation of COPD. Inclusion and exclusion criteria were established (see reference). Patients were randomly assigned to receive either standard treatment (control group) or standard treatment plus Intrapulmonary percussive ventilation (IPV group).

The IPV group underwent two daily sessions of 30 minutes performed by a chest physiotherapist through a full face mask. Thirty minutes of IPV led to a significant decrease in respiratory rate, an increase in PaO2 and a decrease in PaCO2. Exacerbation worsened in 6 out of 17 patients in the control group versus 0 out of 16 in the IPV group. Therapy was tagged successful when both worsening of the exacerbation and a decrease in pH to under 7.35, which would have required non-invasive ventilation, were avoided. Also, the hospital stay was significantly shorter in the IPV group.

IPV is essentially a very effective technique to assist patients to clear retained endobronchial secretions and the resolution of diffuse patchy atelectasis.
