Airway management and ventilation Flashcards
How is airway obstruction noticed?
What are the different noises and where do they indicate the problem is?
Look for chest / abdo movement
(including paradoxical movement - see saw breathing, watching for recession, tug, posture)
Listen and Feel for air movement
Inspiratory stridor - Larynx or above
Expiratory wheeze - Lower airways
Gurgling - Liquid in the upper airways
Snoring - Pharynx is occluded by tongue or palate
What can be done to attempt to ventilate a trache that you cannot do with a larry?
Block a trache and ventilate via mouth
Revise the foreign body algo?
What are the common OPA sizes?
2, 3, 4 (small - large)
Are you better with a larger OPA or smaller?
Larger (but the properly sized one is the best)
What is the final resting place of OPA?
In pharynx with flat area against teeth / gums. It is inserted in upside down technique and rotated 180 degrees
With an OPA, what if a person gags on it?
remove it
Can you use a NPA in basal skull injury if oral airway is not possible?
Yes, provided, gentle insertion is done
What is NPA size for adults?
6-7mm
Insertion technique of NPA
LUBRICATE, safety pin, use twising motion, make sure tube does not blanch nose
What is the tidal volume calculation?
6-7ml / KG
What is the inspiratory time of a breath in ventilation?
~1second
What size of LMA for men vs women?
Men 5, Women 4
Size 4 for igel is suitable for most adults
What size ETT?
Size 4 Mac Blade
7mm for women
8mm for men
What clinical signs are used for ETT insertion confirmation?
