What is the range of flow rate for nasal cannula
1 to 6 lpm
Why is nasal cannula flow rate below 6
Nares adn mucosa dry out when the rate is higher than this - must add humidifier
What are the benefits of a nasal cannula
Can eat, drink, talk still, quiet
But are easily dislodged
How often should nasal canula be changed

Clients wearing a face mask may
Feel claustrophobic
Difference between venturi mask and regular face mask
Venturi allows the nurst to control how much room air is in with the oxygen
Venturi is always used
With COPD because specific O2 concentration should be noted
A partial rebreather look like a facemask with
A reservoir bag attached to it
Partial rebreather allows
Room air to mix with pure oxygen
Reservoir bag should be inflated on a partial rebreather when?
At ALL times - partially inflate before applying
Nonrebreather doesn’t allow
room air to be inhaled
how would you assess to see if oxygens deliver is effective
Pulse ox reading
Respiration rate and pattern
ABG
What shouldn’t be used with oxygen
Petroleum jelly - MUST be water soluble because it can burn a clients face
Do you need a prescription for oxygen
