Abstract:
A comparative study was done using Bear 5 conventional nebulizing cascade system or HCH in the mechanical ventilator circuit. The humidification capacity was nearly the same in both systems although the conventional one originated significantly more "plugs" than the HCH. The circuit contamination was highly more significant in the nebulizer group (63.6%) than in HCH' (8%) (p = 0.0011). The cost of HCH use is less than half of the nebulizing one (US $ 221.64 versus US $ 537.30 per each month.
