QUESTIONS GUARANTEED PASS
◉ What are the low-flow delivery devices?
Answer: Nasal Cannula, Face Mask (Partial Rebreather Mask and
Nonrebreather Mask)
◉ What are the high-flow delivery devices?
Answer: Venturi Mask, Aerosol Mask, Tracheostomy Collar, T-Piece
Adapter, Face Tent, and High-Flow Nasal Canal
◉ Nasal Cannula flow rate and use?
Answer: Delivers 24% (1L/min) to 44% (6L/min) and used in all
care settings and the home. It is the most common, most
comfortable, mobile and least expensive
◉ Simple Face Mask flow rate and use?
Answer: Delivers flow rate 5 to 10 L/min or 40% to 60% and used
for short term use and helpful for transportation
◉ Partial Rebreather Mask flow rate and use
,Answer: Delivers flow rate of 8 to 10 L/min or 50% to 75% oxygen
to patient and used for moderate to high concentration of oxygen
and allows patient to rebreather a portion of exhaled air
◉ Nonrebreather Mask flow rate and use
Answer: Delivers flow rate of 10 L/min or 90% oxygen to patient
and used for high concentrations of oxygen and prevents
rebreathing of CO2
◉ Venturi Mask flow rate and use
Answer: Delivers flow rate of 2 to 15 L/min or 24% to 60% oxygen
and is used for most accurate oxygen concentration using colored
adapters for selecting flow rates
◉ Aerosol Mask use
Answer: Indicated for high humidity oxygen concentration, used for
post-extubation, upper airway surgery and thick secretions
◉ Tracheostomy Collar use
Answer: Used for patients with tracheostomy and requires
humidified oxygen and it can deliver supplemental oxygen
◉ T-Piece Adapter use
, Answer: Used to wean patients off ventilator and used for
spontaneous breathing trials
can be used with endotracheal, nasotracheal or tracheostomy tube
◉ Face Tent use
Answer: Used for facial trauma, burns or upper airway surgery
without putting too much pressure to face and can deliver oxygen
with mixed mist
◉ High-Flow Nasal Cannula use
Answer: Used for air-oxygen blender (blends O2 with compressed
air), active humidifier, single heated tube, and nasal cannula to
deliver heated and humidified medical gas up to 60 L/min
◉ What are the contraindications to oxygen administration?
Answer: Hypercapnia and Hypercarbia (both are terms for high
levels of CO2 in blood)
◉ What are indications for supplemental oxygen?
Answer: Pa02 <60mmHg
Sa02 <90%
Increased need for oxygen (fever, infection, anxiety, and anemia)
