Final Week Review- Oxygen Delivery systems
My take on what you sent me...

low flow
provides some of the patients inspiratory needs
Reservoir
May meet inspiratory needs if no leaks occur
High Flow
always exceeds patients inspirtatory needs
why nasal cannula is the most common
well tolerated, easy to use, simple, low cost, disposable. can be used by all ages
attach cannula to a bubble humidifier
flows are greater than 4L/min and or with infants and children
maximum flow for infants
2L/min
Confused patient removes mask
Restrain Patient
Humidifier pop off activated
find obstruction,omit humidifier
Mask causes claustrophobia
use another device
Bag collapses on inspiration
increase flow
Bag fully inflated on inspiration
correct leak/fix or replace mask as needed
Air Entrainment systems
provide high flow Oxygen
designed to run at 6L/min
Nasal Cannula
nasal sores
disadvantage of a nasal cannula
advanced through the nasal cavity into the oropharynx
nasal catheter
Advantages of Nasal Catheter
Secure placement (infants and toddlers)
Disadvantages of nasal catheter
Painful to insert, can migrate to esophagus, requires routine changes
% of oxygen in atmosperic air
21%
Tidal volume
The volume of air inspired or expired in a single breath during regular breathing. expressed
ml/sec, needs to convert to l/min
has a higher flow of Oxygen than other low flow devices- but not the highest
Simple face mask
used with a bubble humidifier always
Simple face mask
Highest flow of Oxygen possible with low flow delivery
non-rebreathing mask
NRB
Non rebreathing mask
Reservoir of NRB
600-800ml
carries a risk of aspriration of vomitus
Non- Rebreathing mask and partial rebreathing mask
Low Flow device that requires adjustment of flow to meet patient needs
Non rebreathing mask, partial rebreathing mask
When all air flow comes from the device
high flow device
Entrainment
whne one gas sucks another gas out of the way
Gas flow equals
Pressure/gradient airway resistance
Flow
the bulk movement of a volume of liquid per unit of time
velocity
measure of linear distance traveled by a fluid in a unit of time
viscous shearing
the means by which a moving fluid id mixed with a stationary fluid
the smaller the jet orifice
the faster the gas moves
