Case Report

Combined Negative- and Positive-Pressure Ventilation for the Treatment of ARDS

Figure 3

Patient with ARDS in the chamber respirator. CENPV has been discontinued and the chamber opened to enable better access for nursing procedures. The PEEP was elevated before opening the chamber to compensate for discontinuation of end-expiratory negative chamber pressure, and the patient is breathing spontaneously while receiving pressure support from the conventional ventilator. The separate pump unit (bottom right) was manufactured by Coppa S.r.l. (Biella, Italy) and was usually integrated into a tank respirator.
