Objective: To obtain optimal titration of positive end-expiratory pressure (PEEP) during mechanical ventilation with functional residual capacity and ventilation homogeneity measurements.

The system works in both positive and negative pressure modes and HEPA filters both supply and exhaust air. The Institute of Occupational Medicine recently tested this product and found it to be ...
