What are the low-flow delivery devices for oxygen?
Nasal cannula, oxygen-conserving cannula, simple face mask, partial
and nonrebreather masks.
What is the FiO2 range delivered by a nasal cannula?
24%-44% at 1-6 L/min.
What are the advantages of using a nasal cannula?
Safe and simple; easily tolerated; effective for low concentrations;
does not impede eating or talking; inexpensive, disposable.
What are the disadvantages of a nasal cannula?
Unable to use with nasal obstruction; drying to mucous membranes;
can dislodge easily; may cause skin irritation.
What is the FiO2 range delivered by an oxygen-conserving cannula?
8 L/min up to 30%-50%
What are the advantages of using an oxygen-conserving cannula?
Indicated for long-term O2 use in the home; allows increased O2
concentration at lower flow.
,What are the disadvantages of using an oxygen-conserving cannula?
Cannula cannot be cleaned; more expensive than standard cannula.
What is the FiO2 delivered by a simple face mask?
35%-50% at 6-12 L/min.
What are the advantages of using a simple face mask?
Useful for short periods such as patient transportation.
What is a major contraindication for using a simple face mask?
It is contraindicated for patients who retain CO2.
What is the FiO2 delivered by a partial and nonrebreather mask?
increased FiO2 (60%-90%) for short periods.
What are the advantages of partial and nonrebreather masks?
Useful for short periods; delivers increased FiO2; easily humidifies O2;
does not dry mucous membranes. Can irritate skin.
What must be maintained for a nonrebreather mask to function
properly?
The reservoir bag must always remain partially inflated.
What are high-flow delivery devices?
venturi masks and high flow nasal cannulas
What is the FiO2 range for a Venturi mask?
24%-60% at 4-12 L/min.
What are the advantages of using a venturi mask?
, Provides a specific amount of
oxygen with humidity added;
administers low, constant O2.
What are the disadvantages of using a venturi mask?
Mask and added humidity may irritate skin; therapy interrupted with
eating and drinking; specific flow rate must be followed.
What are the advantages of using a high-flow nasal cannula?
Adjustable FiO2 (0.21-1) with modifiable flow up to 60 L/min. Can be
used on any age group.
What are the disadvantages of using a high-flow nasal cannula?
FiO2 dependent on patient
respiratory pattern and input flow; risk for infection.
What is a noninvasive ventilation method?
CPAP and BiPAP
what percentage of FiO2 is delivered with a CPAP and BiPAP?
21-100%
What is the primary use of CPAP and BiPAP?
Use for obstructive sleep apnea.
*Avoid the use of an artificial airway in patients with acute respiratory
distress, respiratory failure, or neuromuscular disorders.
what oxygen delivery device do we start with?
The nasal cannula is the lowest-flow, least invasive device on the
table; safe and simple, easily tolerated, effective for low
concentrations, and the only one that does not impede eating or
talking.
