The concentration of 02 delivered-21% mixes with room air
Delivers the highest concentration of o2- 100%
Not affected by clients breathing pattern cuz valve is already set for a certain amount
Delivers most accurate Fi02
Effective for delivering 02 at 2L/min
Run 02 at 8-10 L, never use with <5L/min
has a higher concentration than nasal cannula
Simple face mask
used on a patient who is in sever respiratory distress, bag must remain at 2/3 full
Delivers 75-90% o2
Which o2 mask is good for COPD
What's the primary goal of 02 therapy?
prevention or treatment of hypoxia, and hypoxemia
Which reduces myocardial effort and the bodys work of breathing
What about o2 in an emergency?
You can administer 02 in an emergency, but if it isnt an emergency you need a doctors order
Nursing intervention to promote a safe environment for receiving 02
- no smoking or electrical equipment
- make sure gauge is on correct setting
- make sure portable tanks is secure
- check nares for irritation
- use water soluble lubricant only (petroleum jelly)
What the purpose of pulse ox?
It measures Sa02 which is the arterial oxygen saturation
Ratio of HGB to total HGB
Adults vs. elderly
- >95% adults
- 93-94% elderly
When getting a pulse ox what's important
- verify capillary refill at site using
- if peripheral circulation is questionable, use an ear lobe or nasal site
- Assess site q4-8 hours and change as needed
Goal of IS
- to reach maximum tidal volume, how much air goes in and out with each insp/exp
Put pt in semi or high fowlers
How do you assess for CSM?
Circulation-color, pulse, temp, cap refill
Sensation-ask pt if they can feel my touch, any tingling or numbness?
Motion/movement-ask pt to move, wiggle fingers and toes
O2 masks Percentage of delivery set 1:
T piece 24-100%
02 masks Percentage of delivery set 2:
Simple Rebreather 40-60%
Partial Rebreather 60-75%
Non Rebreather 80-95%
Minimum flow rate with a simple face mask that ensures flushing of Co2?
Which is more comfy...simple face mask or nasal cannula?
What's important with a partial rebreather mask?
It must remain inflated
The client will rebreathe up to 1/3 of exhaled air together with room air.
What does complete deflation of the reservoir bag during INSPIRATION with a partial re breather mask cause?
Co2 build up
Which mask delivers the highest o2 concentration?
Non rebreather mask
Which mask delivers the most precise oxygen concentration?
What's an aerosol mask?
fits loosely around the face and neck and can provide oxygen to pt. who dont tolerate masks well.
Also good for pt with facial trauma, burns and or thick secretions.
HUMIDIFICATION WITH O2
used for clients with tracheostomies, laryngectomies or endotracheal tubes
has a humidifier
When does a nasal canula need a humidifier?
With flow rates of 4L/min and above
