self inflating manual resuscitators

Question 1

bagger use

Answer 1

CPR cases 
trauma 
critically ill pts transportation 
ventilation of the anesthetic pt 
*any situation requiring initial manual ventilatory support non-invasively or with advance airway

Question 2

bagger

Answer 2

creates positive pressure - makes lung inflate (chest rise) and pushes diaphragm down

Question 3

two types of baggers

Answer 3

self -inflate and flow inflate

Differentiated by how the bagger re-inflates itself during patient exhalation

Question 4

two types of self-inflating baggers

Answer 4

laerdal and ambu

Question 5

components of a self inflating bagger

Answer 5

• pt valve assembly ( three types)
• bag reservoir
• 02 inlet
• gas valve
• optional reservoir

Question 6

non breathing valve

Answer 6

prevents the patient from re inhaling exhaled CO2.
spring loaded
duck bill
leaf
all function similar. closes valve to create a blocking system for the exhaled air to scape so it doesn’t go into bagger reservoir. during exhalation it creates a neg pressure in bag allowing gas to move into bag (inflating).

Question 7

FiO2 when using bagger

Answer 7

can vary when ventilating the pt 
affecting FI02
use of optional reservoir 
oxygen flow
refill time on reservoir bag
re-inflation time 
depends on- rate and volume deliver

Question 8

BVM (bag valve mask)

Answer 8

do not use peep
pressure check device before attach 02
size mask
make a seal use EC clamp technique

Question 9

what to do if the chest does not rise q

Answer 9

re-position mask 
reposition head ( manual manipulations) 
check if obstruction is present (need of an OPA or NPA)
suction 
2 hand technique instead of EC clamp

Question 10

once ventilating you need to continually check for

Answer 10

Chest rise
Adequate ventilation
Patient ventilatory efforts
Patient compliance with ventilation
Change in chest wall compliance or resistance
Vomit or secretions
Ensure adequate respiratory rate
Pt vital signs
