Other Assessment Notes

1. Management algorithm
Describe management for different eventualities:
*Awake, alert, breathing, effective cough - encourage coughing +/- O2
*Ineffective cough (indicates significant obstruction) but conscious
- Up to 5 Back blows, position dependent on size of child, ideally head down
- Alternate 5 back blows, 5 chest thrusts (sharper than CPR) assessing for relief each time
- Abdominal thrusts (Heimlich) not recommended d/t intra-abdo injury
- Attempt visualisation, removal with suction, Magill forceps. Advise against finger sweep d/t injury
- May be able to ventilate with BVM
*Obstruction, hypoxia or apnoea, unconscious
- Commence CPR 15:2, check for FB dislodgement prior to each breath
- High pressure BVM ventilation
- Proceed to RSI and intubation
- If able, remove under direct vision
- Else can push into right main bronchus for bronchoscopic retrieval
- Ventilation in this case of single lung - watch volumes/pressures

2. Teaching technique
- Clear and detailed explanations
- Explore experience and knowledge
- Demonstrate techniques and then critique student's performance of same
- Identify clear learning objectives
- Develop learning plan and actions for student

should the ratio not be 15:2 given that it would not be a lay person doing the CPR in the child
