Q

What is a nasal cannula?
___ - ___ L/min
___ - ___%
humidification needed over ___%
advantages
disadvantages

A

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

Q

What is a simple face mask?
___ - ___ L/min
___ - ___% FI02
advantages
disadvantages

contraindicated for patients with ____

A

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

Q

What is a partial rebreather mask?
__ - __ L/min
__ - __ %
advantages -
disadvantages -

A

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

Q

What is a non-rebreather mask?
___-___ L/min
___-___%
advantages
disadvantages

A

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

Q

What is the difference between a partial and non-rebreather mask?
