- Screw the top of the nebulizer back on.
- Connect the nebulizer to the mask.
- Dispose of sharps in a safety box.
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.
Monitoring
- 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.
