100% Correct 2025/2026.
What are the three low flow oxygen therapies?
Nasal Cannula
Partial Non-rebreather
Non-rebreather
What does low flow device mean?
Delivers low concentration of oxygen
Characteristics of nasal cannula
Low flow oxygen therapy
Light weight & portable
Disadvantage to NC?
nasal mucosal drying
skin break down behind ear, cheeks, generalized edema
If the flow is higher than 4L/min for NC- what needs to be done?
Needs to be humidified
When is NC sometimes ordered?
patients post op 24 hours
Characteristics of a partial non-rebreather?
Low flow oxygen
Moderate oxygen concentration
Oxygen flows into bag
NO VALVE- which allows client to rebreathe up to one third of exhaled air together with RA.
disadvantage to Partial NB?
Warm, poorly fitted, must remove to eat
Use with CAUTION for clients who have high risk for aspiration or airway obstruction.
Characteristics of Non-rebreather?.
Low flow oxygen
Delivers highest concentration of oxygen (excpet for intubation)
Also has a bag
Disadvantages of NB?
, Poorly fitting
** Watch for skin breakdown
Valve and flap on the mask must be intact and functional during each breath.
Poorly tolerated by clients who have anxiety or claustrophobia.
Eating, drinking, and talking are impaired.
Also Use with CAUTION for clients who have high risk for aspiration or airway obstruction.
Non-rebreathers have additional...
Valves, one way valves located at exhalation ports and prevent RA from entering
What are the three High flow oxygen therapies?
Aerosol mask
Face tent
Venturi Mask
Characteristics of Aerosol mask?
Hooked to medical air

Accurate FiO2
Disadvantages of aerosol mask?
uncomfortable to some patients
Characteristics of Face tent?
High flow oxygen
Good humidity
FAIRLY accurate FiO2
Disadvantages of Face tent?
bulky and cumbersome
Functional unit of the lung?
Alveoli
Characteristics of Venturi Mask?
High flow system
Provides low levels of supplemental O2
Has dials on it
Which of the three high flow oxygen therapies is the most reliable for delivering accurate levels
through a non-invasive method?
Venturi Mask
Disadvantages of Venturi Mask?
Must remove to eat
