A low flow delivery system does what? - answer✔Delivers air through a nasal cannula or a
simple mask that does not fit tightly against the childs face.
Low flow systems provide how much inspired O2 concentration?
Who uses them? - answer✔22- 60%
Used for stable children who require a low inspired O2 concentration, such a when a child is not
in severe respiratory distress or shock
Examples of low flow systems? - answer✔Nasal cannula and simple mask
O2 flow rate for nasal cannula - answer✔0.25 to 4 L/min
Simple mask flow rate? - answer✔6-10 L/min Inspired O2 concentration of 35- 60%
Why cant the simple mask deliver inspired O2 concentration greater than 60%? -
answer✔Because room air enters between the mask and face during inspiration
high flow O2 delivery systems do what? Flow rate?
When should they be used?
Most common example of High flow O2 system? - answer✔Deliver O2 concentration 60% or
greater (95%) . Flow rate is 10L.
Used in emergency situations whenever the child has respiratory distress or shock
Nonrebreathing mask valves do what? - answer✔A valve in 1 or both exhalation ports to prevent
room air from entering during inspiration
Valve between reservoir bag and mask to prevent flow of exhaled gas into reservoir
How do you prevent bag collapse in nonrebreather? - answer✔Adjust O2 flow rate into mask.
Greater than 10L
During inspiration how much O2 is drawn by the child with a nonrebreather? - answer✔100%
from the reservoir bag and O2 inflow
High Flow nasal cannula - answer✔O2 can be adjusted from 4 L in infants up to 40 L or more in
adolescents. Deliver a combo of room air and oxygen.
Gas flow for nebulizer? How long? - answer✔5-6L/min
8-10 min
Does skin pigment affect accuracy or function of the pulse oximeter? - answer✔False
What must you confirm with a pulse ox? - answer✔Confirm validity of oximeter data by
evaluating Childs appearance. Also compare HR displayed by pulse ox with HR displayed by the
bedside monitor
respiratory arrest - answer✔The absence of respirations (apnea) with detectable cardiac activity.
Must provide rescue breathing to prevent cardiac arrest
When should endotracheal intubation be considered? - answer✔If the child is unstable to
maintain effective airway, oxygenation, or ventilation despite initial intervention.
