Noninvasive Oxygen Delivery Methods Low Flow include what
- Nasal canula
- Simple face mask
- Partial rebreather mask
- Nonrebreather mask
Noninvasive Oxygen Delivery Methods Low Flow: Nasal Canula (Delivery, areas of use)
Delivers 24% (1L/min)-44% (6L/min)
Used in all care settings and the home
What is the most common delivery method of O2?
Nasal Canula
Benefits of the Nasal Canula?
Most common
Most comfortable
Mobile
Less expensive
Noninvasive Oxygen Delivery MethodsLow Flow: Simple Face Mask
(Flow rate or delivery); how often is it used? What is it used for?
Flow rates 5-10 L/min or 40%-60%
Used short term
Helpful for transport
Noninvasive Oxygen Deliver MethodsLow Flow: Partial rebreather mask
Simple mask with reservoir bag attached
Reservoir bag filled with oxygen
Noninvasive Oxygen Deliver MethodsLow Flow: Partial rebreather mask (Flow rate and delivery)
Flow rate of 8-10L/min
50%-75% oxygen to patient
Noninvasive Oxygen Delivery MethodsLow Flow: Nonrebreather Mask
One-way valves between mask and bag
One-way valves on side of mask
Prevents rebreathing of CO2
