– Screw the top of the nebulizer back on.
– Connect the nebulizer to the mask.

Administering the aerosol
– Explain the procedure to the child and the person accompanying him: the inhalation lasts about 10 minutes; keep the mask on and breathe slowly and deeply the entire time.
– Have the parents hold the child in a half-seated position.
– Clear the nose, if necessary.
– Attach the tubing to the compressor.
– Start the compressor. Make sure there is mist coming out of the mask.
– Place the mask over the child’s mouth and nose; secure it in place with the strap.
– The inhalation should last no longer than 10 to 12 minutes. Stop the compressor after 10 to 12 minutes (or sooner, if all of the medicine has been nebulised).
– Record the procedure in the patient’s chart.
– Before nebulization: heart rate, respiratory rate and, if possible, SpO2.
– During the nebulization and for 4 hours afterward:
• general condition, level of consciousness, respiratory rate, and SpO2;
• signs of improvement: decreased stridor and improvement in ventilation, level of consciousness and SpO2;
• alert the doctor in case of pallor, tachycardia, arrhythmia, or drop in SpO2 (< 90%).
– Record the monitoring data in the patient’s chart.
16.4 After using the equipment
– Discard the tubing and mask.
– Disassemble the nebulizer and clean all of the parts in soapy water, taking care not to damage the jet (do not use a brush).
– For equipment maintenance (jet, compressor air filter), refer to specific protocol.
