Identify and explain
Compression of a self-inflating bag delivers gas through a valve and a patient interface when a suitable seal and airway are established.
- Compressible bag
- Valve assembly
- Face mask or patient connection
Prepare
Check function, correct size and appropriate oxygen accessories.
Monitor
Ventilation effectiveness and over-ventilation risks require trained assessment.
At the viva table
Try answering aloud, then open the suggested answer. Examiner questions vary.
01 / Does squeezing the bag guarantee effective ventilation?
No. Airway patency, seal, technique and patient factors matter.
02 / What does the valve do?
It directs gas flow and separates inspiratory and expiratory pathways as designed.
03 / Is one mask size suitable for every person?
No. Choose an appropriate interface.
04 / Why avoid excessive ventilation?
It can cause harm, including gastric inflation and adverse physiological effects.
