Be sure nebulizer has been sterilized before use. Don't compromise
sterility in handling.
Don't overfill reservoir. Use single-distilled (not just sterile)
O2 flow is limited by the nebulizer jet. Two
nebulizers may be needed to meet inspiratory demand with high O2
Don't connect aerosol to patient before heater has fully warmed up.
Check mist temperature regularly at patient end of tubing using a
continuous, in-line thermometer.
Don't let accumulated moisture in aerosol tubing drain into the
patient or contaminate the reservoir. Position tubing carefully, and
drain periodically from patient end. When possible, use condensation
If the nebulizer does not produce a visible mist, check for blocked
gas or liquid orifice; clear with fine wire.
Never fully immerse heaters during cleaning or disinfection. Follow
