Oxygen Delivery Devices (Review from Lab) Flashcards
What is a nasal cannula?
___ - ___ L/min
___ - ___%
humidification needed over ___%
advantages
disadvantages
1-6 L/min: 24-44%
Typically humidification is needed if flow rate = or > than 4 L/min (due to drying)
Advantages: Safe & simple, easily tolerated, effective for low concentrations, does not impede talking or eating, inexpensive & disposable
Disadvantage: Drying to mucous membranes, dislodges easily, may cause skin irritation/breakdown around ears & nares, patient’s breathing pattern (mouth vs nasal) affects exact FiO2
What is a simple face mask?
___ - ___ L/min
___ - ___% FI02
advantages
disadvantages
contraindicated for patients with ____
6-12 L/min: 35-50% FI02
Advantages: Useful for short periods such as patient transportation
Disadvantages: Contraindicated for patients who retain CO2, may induce feelings of claustrophobia, therapy interrupted with eating & drinking, increased risk for aspiration
What is a partial rebreather mask?
__ - __ L/min
__ - __ %
advantages -
disadvantages -
10-15 L/min: 60%-90%; reservoir bag should remain partially inflated AAT
Advantages: Useful for short periods, delivers increased FiO2 than simple face mask, easily humidifies O2, does not dry mucous membranes
Disadvantages: Hot & confining, may irritate skin, tight seal necessary, interferes with eating & talking, bag may twist or kink, should not totally deflate
What is a non-rebreather mask?
___-___ L/min
___-___%
advantages
disadvantages
10-15 L/min: 70%-90%; reservoir bag should remain partially inflated AAT
Contains one-way valves with reservoir; exhaled air does not enter reservoir bag
Advantages: Useful for short periods, delivers increased FiO2 than simple face mask, easily humidifies O2, does not dry mucous membranes
Disadvantages: Hot & confining, may irritate skin, tight seal necessary, interferes with eating & talking, bag may twist or kink, should not totally deflate
What is a Venturi (Venti) mask?
___-___%
advantages
typically used for patients with ___ who need ___ and ____ oxygen concentrations
24-60%
Provides specific amount of oxygen; high-flow & precise. Typically used for patients with COPD who need low, constant oxygen concentrations.
What is the difference between a partial and non-rebreather mask?
Partial rebreathers use the reservoir bag to capture some exhaled gas for rebreathing whereas non-rebreathers have a valve that prevents exhaled air from entering the reservoir bag
What is a high-flow nasal cannula?
up to ___ L/min
used to treat ____
Adjustable Fi92 (0.21-1) with modifiable flow (up to 60 L/min)
Can humidify & warm.
Used to treat respiratory failure.
