Multicenter Study Comparative Study
Iron lung vs mask ventilation in the treatment of acute on chronic respiratory failure in COPD patients: a multicenter study.
Evaluation of the effectiveness of negative-pressure ventilation (NPV) with the use of the iron lung vs noninvasive positive-pressure ventilation (NIPPV) in the treatment of COPD patients with acute on chronic respiratory failure. ⋯ These data suggest that both ventilatory techniques are equally effective in avoiding EI and death in COPD patients with ARF. Prospective trials are needed to confirm these preliminary results.
