Q

How do you assess the airway?

A

Protect cervical spine if an injury is possible
Look inside the mouth and remove objects/dentures
Assess for signs of obstruction
○ Use wide-bore suction under direct vision if secretions are present
If vocalising, can assume airway is patent
Listen for stridor, snoring or gurgling
Establish a patent airway using:
○ Manoeuvres (e.g. chin lift, jaw thrust)
○ Adjuncts (e.g. oropharyngeal airway (Guedel))
If airway still impaired –> CALL ARREST TEAM (2222)

Q

How do you assess breathing?

A

Look for chest expansion (equal? Fogging of mask?)
Listen for air entry (equal?)
Feel for expansion and percussion (equal?)
Start 15 L oxygen via a non-rebreather
Use a bag valve mask if there is poor or absent respiratory effort
Monitor SaO2 and RR
Check for tracheal deviation and cyanosis
If NO respiratory effort –> CALL ARREST TEAM (2222)
