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?
ETCO2, bilateral axilla auscultation, epigastric auscultation
Will ETCO2 help with bronchial vs trachea placement confirmation?
No
